||||
### 🔧 Fixed
|
||||
- **Race Condition**: Fixed progress tracking goroutine race condition by using proper stderr pipes instead of shared buffer
|
||||
- **Progress Parsing**: Improved FFmpeg output parsing with better validation and error handling for format changes
|
||||
- **Flag Validation**: Fixed `--abr` flag to properly error when no bitrate value is provided
|
||||
- **Multiple Files Progress**: Fixed progress output for multiple files to prevent messy overlapping progress lines
|
||||
- **Container Compatibility**: Fixed `--tiny --nvhevc` to use MP4 container instead of WEBM
|
||||
- **Conflict Detection**: Added proper error handling for conflicting `--x264` and `--nvhevc` flags
|
||||
- **Stats System**: Completely rewrote to accumulate data properly:
|
||||
- `total_files` now properly increments instead of always showing "1"
|
||||
- `total_time` accumulates encoding time across sessions
|
||||
- `average_time` calculated correctly from accumulated data
|
||||
- Data persists across sessions for long-term tracking
|
||||
- **Error Handling**: Improved handling for missing flag values

**Purpose**: Caps video bitrate to control file size
|
||||
**Default**: Mode-specific (1500-3000 kbps)
|
||||
|
||||
**Why use it**:
|
||||
- Control file sizes
|
||||
- Meet platform requirements
|
||||
- Bandwidth limitations
|
||||
- Storage constraints
|
||||
|
||||
**Examples**:
|
||||
```bash
|
||||
./gwencoder --fast --maxrate 5000 # 5 Mbps max
|
||||
./gwencoder --web --maxrate 2000 # 2 Mbps max
|
||||
./gwencoder --tiny --maxrate 1000 # 1 Mbps max
|
||||
```
|
||||
|
||||
**Bitrate Guidelines**:
|
||||
- **500-1000 kbps**: Very low quality, tiny files
|
||||
- **1000-2000 kbps**: Low quality, small files
|
||||
- **2000-5000 kbps**: Good quality, medium files
|
||||
- **5000-10000 kbps**: High quality, large files
|
||||
- **10000+ kbps**: Very high quality, very large files

## Advanced Usage
|
||||
|
||||
### Combining Options
|
||||
|
||||
```bash
|
||||
# High-quality H.264 with custom settings
|
||||
./gwencoder --quick --x264 --maxrate 8000 --abr 128
|
||||
|
||||
# Web-optimized with hardware acceleration
|
||||
./gwencoder --web --nvhevc --maxrate 3000
|
||||
|
||||
# Tiny files with maximum compression
|
||||
./gwencoder --tiny --maxrate 1000 --abr 32
|
||||
```
|
||||
|
||||
### Batch Processing
|
||||
|
||||
GWEncoder automatically processes all supported video files in the current directory:
|
||||
|
||||
```bash
|
||||
# Process all videos in current directory
|
||||
./gwencoder --fast
|
||||
|
||||
# Process specific files (place in directory with only those files)
|
||||
mkdir batch_processing
|
||||
cp video1.mp4 video2.mkv batch_processing/
|
||||
cd batch_processing
|
||||
./gwencoder --web
|
||||
```
|
||||
|
||||
### File Naming Convention
|
||||
|
||||
Output files follow this pattern:
|
||||
```
|
||||
[original_name]-[CODEC]-[MODE]-GWELL.[extension]
|
||||
```
|
||||
|
||||
Examples:
|
||||
- `video.mp4` → `video-AV1-Fast-GWELL.mkv`
|
||||
- `movie.mkv` → `movie-H264-Web-Optimized-GWELL.mkv`
|
||||
- `clip.avi` → `clip-NVHEVC-Quick-GWELL.mkv`
|
||||
|
||||
### Supported Input Formats

## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### "FFmpeg not found"
|
||||
**Problem**: GWEncoder can't find FFmpeg
|
||||
**Solution**:
|
||||
```bash
|
||||
# Check if FFmpeg is installed
|
||||
ffmpeg -version
|
||||
|
||||
# Install FFmpeg if missing
|
||||
sudo apt install ffmpeg # Ubuntu/Debian
|
||||
brew install ffmpeg # macOS
|
||||
```
|
||||
|
||||
#### "No video files found"
|
||||
**Problem**: No supported video files in directory
|
||||
**Solution**:
|
||||
```bash
|
||||
# Check current directory
|
||||
ls -la *.mp4 *.mkv *.avi *.webm
|
||||
|
||||
# Move to directory with video files
|
||||
cd /path/to/video/files
|
||||
./gwencoder --fast
|
||||
```
|
||||
|
||||
#### "Permission denied"
|
||||
**Problem**: Can't execute gwencoder
|
||||
**Solution**:
|
||||
```bash
|
||||
chmod +x gwencoder
|
||||
```
|
||||
|
||||
#### "Out of memory" or "Encoding too slow"
|
||||
**Problem**: System resources insufficient
|
||||
**Solutions**:
|
||||
- Use `--tiny` mode for smaller files
|
||||
- Use `--x264` for faster encoding
|
||||
- Use `--nvhevc` if you have NVIDIA GPU
|
||||
- Close other applications
|
||||
- Process files one at a time
|
||||
|
||||
#### "NVIDIA NVENC not available"
|
||||
**Problem**: `--nvhevc` fails
|
||||
**Solutions**:
|
||||
- Check if you have NVIDIA GPU
|
||||
- Update NVIDIA drivers
|
||||
- Use `--x264` instead
|
||||
- Use default AV1 encoding
|
||||
|
||||
### Performance Optimization
|
||||
|
||||
#### For Speed:
|
||||
```bash
|
||||
# Use H.264 for fastest encoding
|
||||
./gwencoder --fast --x264
|
||||
|
||||
# Use hardware acceleration if available
|
||||
./gwencoder --fast --nvhevc
|
||||
|
||||
# Use tiny mode for smallest files
|
||||
./gwencoder --tiny
|
||||
```
|
||||
|
||||
#### For Quality:
|
||||
```bash
|
||||
# Use higher bitrates
|
||||
./gwencoder --quick --maxrate 8000
|
||||
|
||||
# Use higher audio bitrates
|
||||
./gwencoder --fast --abr 128
|
||||
|
||||
# Use AV1 for best compression
|
||||
./gwencoder --quick # (default AV1)
|
||||
```
|
||||
|
||||
#### For Compatibility:
|
||||
```bash
|
||||
# Use H.264 with MP4
|
||||
./gwencoder --web --x264
|
||||
|
||||
# Use AAC audio
|
||||
./gwencoder --fast --aac
|
||||
```
|
||||
|
||||
### Log Files
|
||||
|
||||
GWEncoder creates several log files for troubleshooting:
|
||||
|
||||
- **`gwencoder_log.txt`**: Successful encoding history
|
||||
- **`gwencoder_errors.txt`**: Error details and FFmpeg output
|
||||
- **`gwencoder_stats.json`**: Encoding statistics and performance data
|
||||
|
||||
Check these files if you encounter issues:
|
||||
```bash
|
||||
# View recent errors
|
||||
tail -20 gwencoder_errors.txt
|
||||
|
||||
# View encoding history
|
||||
tail -20 gwencoder_log.txt
|
||||
|
||||
# View statistics
|
||||
cat gwencoder_stats.json
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Technical Details
|
||||
|
||||
### Architecture
|
||||
|
||||
GWEncoder is built with a modular architecture:
|
||||
|
||||
```
|
||||
gwencoder/
|
||||
├── main.go # Main application logic
|
||||
└── gwutils/ # Shared utilities package
|
||||
├── common.go # Common functions
|
||||
└── config.go # Configuration structures
|
||||
```
|
||||
|
||||
### FFmpeg Integration
|
||||
|
||||
GWEncoder uses FFmpeg for all video processing:
|
||||
|
||||
- **Video Encoding**: libsvtav1, libx264, hevc_nvenc
|
||||
- **Audio Encoding**: libopus, aac
|
||||
- **Container Support**: MKV, MP4, WEBM
|
||||
- **Progress Parsing**: Real-time FFmpeg output analysis
|
||||
|
||||
### Performance Characteristics
|
||||
|
||||
#### Encoding Speed (relative):
|
||||
1. **NVIDIA NVENC HEVC**: Fastest (hardware accelerated)
|
||||
2. **H.264/x264**: Fast (software, optimized)
|
||||
3. **AV1**: Slower (software, high compression)
|
||||
|
||||
#### File Size (relative):
|
||||
1. **AV1**: Smallest files
|
||||
2. **HEVC**: Medium files
|
||||
3. **H.264**: Largest files
|
||||
|
||||
#### Quality (at same bitrate):
|
||||
1. **AV1**: Best quality
|
||||
2. **HEVC**: Good quality
|
||||
3. **H.264**: Good quality
|
||||
|
||||
### Memory Usage
|
||||
|
||||
- **Typical**: 200-500 MB RAM
|
||||
- **Peak**: 1-2 GB RAM (depending on video resolution)
|
||||
- **Recommendation**: 4+ GB RAM for 1080p, 8+ GB for 4K
|
||||
|
||||
### CPU Usage
|
||||
|
||||
- **AV1**: High CPU usage, benefits from many cores
|
||||
- **H.264**: Medium CPU usage, good single-core performance
|
||||
- **NVENC**: Low CPU usage (GPU does the work)
|
||||
|
||||
### Storage Requirements
|
||||
|
||||
- **Temporary**: ~2x input file size during encoding
|
||||
- **Output**: Varies by settings (typically 10-50% of input size)
|
||||
- **Logs**: Minimal (few MB per encoding session)
|
||||
|
||||

|
||||
|
||||
## Best Practices
|
||||
|
||||
### Choosing the Right Mode
|
||||
|
||||
1. **For Web Uploads**: Use `--web` mode
|
||||
2. **For Local Storage**: Use `--fast` or `--quick` mode
|
||||
3. **For Archival**: Use `--tiny` mode
|
||||
4. **For Compatibility**: Use `--x264` codec
|
||||
5. **For Speed**: Use `--nvhevc` if available
|
||||
|
||||
### File Size Management
|
||||
|
||||
1. **Large Files**: Use `--tiny` mode or lower `--maxrate`
|
||||
2. **Quality Priority**: Use `--quick` mode with higher `--maxrate`
|
||||
3. **Storage Optimization**: Use AV1 codec with appropriate CRF
|
||||
|
||||
### Batch Processing
|
||||
|
||||
1. **Organize Files**: Group similar content together
|
||||
2. **Test First**: Try one file before batch processing
|
||||
3. **Monitor Resources**: Watch CPU/memory usage
|
||||
4. **Backup Originals**: Keep source files safe
|
||||
|
||||
### Quality vs. Speed Trade-offs
|
||||
|
||||
1. **Speed Priority**: H.264 + fast preset
|
||||
2. **Quality Priority**: AV1 + quality preset
|
||||
3. **Balanced**: AV1 + balanced preset
|
||||
4. **Storage Priority**: AV1 + high CRF + low maxrate

||||
4. Documentation: Check `docs/` directory for all documentation
|
||||
|
||||
### Technical Details
|
||||
- No breaking changes to CLI interface or encoding functionality

|
||||
./build/gwencoder --fast --use-cc-extractor --embed-extracted-cc
|
||||
```
|
||||
|
||||
**Note**: Requires `ccextractor` in PATH. If unavailable, extraction is skipped with a warning.
|
||||
|
||||
## Video Options
|
||||
|
||||
### Bitrate Control
|
||||
|
||||
```bash

||||
Error: FFmpeg not available
|
||||
```
|
||||
**Solution**: Install FFmpeg and ensure it's in your PATH
|
||||
|
||||
**ccextractor not found**
|
||||
```
|
||||
⚠️ ccextractor not available in PATH, skipping CC extraction
|
||||
```
|
||||
**Solution**: Install ccextractor or disable CC extraction
|
||||
|
||||
## Supported Formats
|
||||
|
||||
### Input Formats
|
||||
- WMV, AVI, MP4, MKV, MPG, TS, WEBM
|
||||
|
||||
### Output Formats
|
||||
- MKV (default for most modes)
|
||||
- MP4 (for compatibility)
|
||||
- WEBM (for web distribution)
|
||||
|
||||
## Advanced Features
|
||||
|
||||
### Resolution-Aware CRF Adjustment
|
||||
|
||||
GWEncoder automatically adjusts CRF based on video resolution:
|
||||
- **4K (2160p)**: CRF +2 (higher quality needed)
|
||||
- **1080p**: No adjustment
|
||||
- **720p**: CRF -2 (lower quality acceptable)
|
||||
|
||||
### Smart Container Selection
|
||||
|
||||
Automatically switches to MP4 when:
|
||||
- Input is Apple/broadcast format (MP4/MOV)
|
||||
- Unsupported subtitle streams detected (EIA-608, CC_DEC, tx3g)
|
||||
|
||||
### Stream Filtering
|
||||
|
||||
Unsupported streams are automatically filtered for MKV output:
|
||||
- EIA-608 closed captions
|
||||
- CC_DEC streams
|
||||
- tx3g subtitles
|
||||

|
||||
| `Makefile` | Build automation |

|
||||
| `tests/artifacts/.gitkeep` | Preserve directory |
|
||||
| `tests/logs/.gitkeep` | Preserve directory |
|
||||
| `tests/outputs/.gitkeep` | Preserve directory |
|
||||
|
||||
## Import Path Changes
|
||||
|
||||
For developers modifying the code:
|
||||
|
||||
**Old import:**
|
||||
```go
|
||||
import "gwencoder/encoding"
|
||||
```
|
||||
|
||||
**New import:**
|
||||
```go
|
||||
import "gwencoder/pkg/encoding"
|
||||
```
|
||||
|
||||
## Build Command Changes
|
||||
|
||||
**Old build process:**
|
||||
```bash
|
||||
go build -o gwencoder
|
||||
./gwencoder --help
|
||||
```
|
||||
|
||||
**New build process:**
|
||||
```bash
|
||||
make build
|
||||
./build/gwencoder --help
|
||||
```
|
||||
|
||||
## Test Script Changes
|
||||
|
||||
Scripts now reference new paths:
|
||||
- Test media: `../tests/artifacts/testvid.webm`
|
||||
- Test results: `../tests/logs/test_results.txt`
|
||||
- Run from: `scripts/` directory
|
||||
|
||||
## Benefits of This Reorganization
|
||||
|
||||
1. **Standard Go Layout**: Follows Go community conventions
|
||||
2. **Separation of Concerns**: Clear boundaries between code, docs, tests, scripts
|
||||
3. **Git Hygiene**: Proper exclusion of binaries and artifacts
|
||||
4. **Documentation**: Organized by purpose (phases, reference, guides)
|
||||
5. **Build System**: Makefile simplifies common tasks
|
||||
6. **CI/CD Ready**: Standard structure for automated pipelines
|
||||
7. **Maintainability**: Easier to onboard new contributors
|
||||
8. **Scalability**: Room to add new packages and tools
|
||||
|
||||
## Quick Reference Commands
|
||||
|
||||
```bash
|
||||
# Build the project
|
||||
make build
|
||||
|
||||
# Run tests
|
||||
cd scripts && ./run_tests.sh
|
||||
|
||||
# Clean build artifacts
|
||||
make clean
|
||||
|
||||
# Install to system
|
||||
make install
|
||||
|
||||
# View help
|
||||
make help
|
||||
|
||||
# Run the binary
|
||||
./build/gwencoder --help
|
||||
```
|
||||
|
||||
## Rollback (If Needed)
|
||||
|
||||
If you need to revert to the old structure:
|
||||
1. Copy files from `.archive/` back to root
|
||||
2. Use `git checkout` to restore original file locations
|
||||
3. Note: This is not recommended as the new structure is superior
|
||||
|
||||
## Questions?
|
||||
|
||||
See `docs/PROJECT_STRUCTURE.md` for detailed documentation of the new layout.

# Resolution Preset Code Integration
|
||||
|
||||
## Quick Integration Steps
|
||||
|
||||
Since you have `main.go` open in your editor, here are the exact code additions needed:
|
||||
|
||||
### 1. EncodingOptions Struct
|
||||
Find `type EncodingOptions struct` and add:
|
||||
```go
|
||||
Resolution string // Resolution preset (480p, 720p, 1080p, original)
|
||||
```
|
||||
|
||||
### 2. Flag Parsing
|
||||
In `parseFlags()`, add with other flag definitions:
|
||||
```go
|
||||
resolution := flag.String("resolution", "", "Target resolution (480p, 720p, 1080p, original)")
|
||||
```
|
||||
|
||||
And in the `EncodingOptions` initialization:
|
||||
```go
|
||||
Resolution: *resolution,
|
||||
```
|
||||
|
||||
### 3. encodeFile() Integration
|
||||
Add this near the start of `encodeFile()`, before building FFmpeg command:
|
||||
|
||||
```go
|
||||
// Build scale filter for resolution preset
|
||||
scaleFilter := ""
|
||||
if opts.Resolution != "" {
|
||||
filter, err := encoding.BuildScaleFilter(file, opts.Resolution)
|
||||
if err != nil {
|
||||
fmt.Printf("⚠️ Warning: Could not build scale filter: %v\n", err)
|
||||
} else if filter != "" {
|
||||
scaleFilter = filter
|
||||
targetHeight := encoding.GetResolutionPresetHeight(opts.Resolution)
|
||||
fmt.Printf("📐 Scaling video to %dp\n", targetHeight)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Then when building FFmpeg args, add the scale filter if not empty:
|
||||
```go
|
||||
if scaleFilter != "" {
|
||||
ffmpegArgs = append(ffmpegArgs, strings.Fields(scaleFilter)...)
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Help Text
|
||||
In `printHelp()`, add:
|
||||
```go
|
||||
fmt.Println("\n📐 Resolution Options:")
|
||||
fmt.Println(" --resolution <preset> Scale to target resolution (480p, 720p, 1080p)")
|
||||
fmt.Println(" Only scales down, maintains aspect ratio")
|
||||
```
|
||||
|
||||
## Test Commands
|
||||
|
||||
After saving and rebuilding:
|
||||
```bash
|
||||
make clean && make build
|
||||
./build/gwencoder --help | grep -A 5 "Resolution"
|
||||
./build/gwencoder --fast --resolution 720p input.mp4
|
||||

## File Organization Principles
|
||||
|
||||
### 1. **Separation of Concerns**
|
||||
- **`cmd/`**: Application entry points only
|
||||
- **`pkg/`**: Reusable library code
|
||||
- **`docs/`**: All documentation grouped by purpose
|
||||
- **`scripts/`**: Executable helper scripts
|
||||
- **`tests/`**: Test data and outputs
|
||||
- **`logs/`**: Runtime artifacts
|
||||
|
||||
### 2. **Build Artifacts**
|
||||
- All compiled binaries go in `build/`
|
||||
- Git-ignored to keep the repository clean
|
||||
- Easily cleaned with `make clean`
|
||||
|
||||
### 3. **Documentation Categories**
|
||||
- **`phases/`**: Historical development records
|
||||
- **`reference/`**: Technical specifications
|
||||
- **`guides/`**: User-facing documentation
|
||||
|
||||
### 4. **Test Organization**
|
||||
- **`artifacts/`**: Input test media
|
||||
- **`logs/`**: Execution logs and results
|
||||
- **`outputs/`**: Encoded output files
|
||||
|
||||
### 5. **Legacy Code**
|
||||
- Old binaries archived in `.archive/`
|
||||
- Git-ignored but preserved for reference
|
||||
- Separated from active development
|
||||
|
||||
## Key Files
|
||||
|
||||
### Source Code
|
||||
| File | Purpose |
|
||||
|------|---------|
|
||||
| `cmd/gwencoder/main.go` | Main application entry point with CLI parsing, encoding orchestration |
|
||||
| `pkg/encoding/audio.go` | Audio stream analysis, codec selection, bitrate calculation |
|
||||
| `pkg/encoding/av1.go` | AV1 encoding parameters, CRF adjustment, quality control |
|
||||
| `pkg/encoding/streams.go` | Stream reordering, subtitle handling, CC extraction |
|
||||
|
||||
### Configuration
|
||||
| File | Purpose |
|
||||
|------|---------|
|
||||
| `go.mod` | Go module definition and dependencies |
|
||||
| `Makefile` | Build automation and common tasks |
|
||||
| `.gitignore` | Git exclusion rules for artifacts and binaries |
|
||||
|
||||
### Documentation
|
||||
| File | Purpose |
|
||||
|------|---------|
|
||||
| `README.md` | Main project documentation and quick start guide |
|
||||
| `docs/reference/FLAG_REFERENCE.md` | Complete CLI flag documentation |
|
||||
| `docs/guides/TROUBLESHOOTING.md` | Common issues and solutions |
|
||||
|
||||
## Build System
|
||||
|
||||
The project uses a Makefile for build automation:
|
||||
|
||||
```bash
|
||||
make build # Build the binary
|
||||
make clean # Remove build artifacts
|
||||
make test # Run tests
|
||||
make install # Install to GOPATH/bin
|
||||
make deps # Download dependencies
|
||||
make tidy # Tidy go.mod
|
||||
make help # Show available targets
|
||||
```
|
||||
|
||||
## Import Structure
|
||||
|
||||
The main application imports the encoding package:
|
||||
|
||||
```go
|
||||
import (
|
||||
"gwencoder/pkg/encoding"
|
||||
"gwutils" // External utility library
|
||||
)
|
||||
```
|
||||
|
||||
The `gwutils` package is a sibling module in the parent directory, referenced via `go.mod` replace directive.
|
||||
|
||||
## Git Ignore Strategy
|
||||
|
||||
The following are excluded from version control:
|
||||
- **Binaries**: `build/`, `.archive/`, `*.exe`, `*.so`, etc.
|
||||
- **Logs**: `logs/`, `tests/logs/`, `*.log`
|
||||
- **Test artifacts**: Large media files, encoded outputs
|
||||
- **IDE files**: `.vscode/`, `.idea/`, `*.swp`
|
||||
- **Temporary files**: `tmp/`, `*.tmp`
|
||||
|
||||
Empty directories are preserved with `.gitkeep` files.
|
||||
|
||||
## Development Workflow
|
||||
|
||||
1. **Edit source**: Modify files in `cmd/` or `pkg/`
|
||||
2. **Build**: Run `make build`
|
||||
3. **Test**: Execute scripts in `scripts/` directory
|
||||
4. **Document**: Update relevant docs in `docs/`
|
||||
5. **Commit**: Only source code and documentation
|
||||
|
||||
## Migration Notes
|
||||
|
||||
This structure was reorganized from the original flat layout to improve:
|
||||
- **Discoverability**: Easier to locate files by category
|
||||
- **Maintainability**: Clearer separation of concerns
|
||||
- **CI/CD**: Standard Go project layout for automated builds
|
||||
- **Documentation**: Grouped and categorized for better navigation
|
||||
- **Collaboration**: Conventional structure familiar to Go developers
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
Potential improvements to consider:
|
||||
- Add `internal/` package for non-exported code
|
||||
- Create `api/` directory if exposing a library interface
|
||||
- Add `examples/` directory with usage examples
|
||||
- Consider `docker/` directory for container builds
|
||||
- Add `ci/` directory for GitHub Actions or CI/CD configs

# Resolution Preset Implementation Guide
|
||||
|
||||
## Changes Required to cmd/gwencoder/main.go
|
||||
|
||||
Since `cmd/gwencoder/main.go` is in `.gitignore`, here's a guide for the manual changes needed:
|
||||
|
||||
### 1. Add Resolution field to EncodingOptions struct
|
||||
|
||||
Find the `EncodingOptions` struct (around the top of the file or where flags are defined) and add:
|
||||
|
||||
```go
|
||||
type EncodingOptions struct {
|
||||
// ... existing fields ...
|
||||
|
||||
// Resolution preset
|
||||
Resolution string // "480p", "720p", "1080p", or "original"
|
||||
|
||||
// ... rest of existing fields ...
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Add --resolution flag in parseFlags() function
|
||||
|
||||
Find the `parseFlags()` function and add this flag definition with the other flags:
|
||||
|
||||
```go
|
||||
func parseFlags() EncodingOptions {
|
||||
// ... existing flag definitions ...
|
||||
|
||||
// Resolution preset
|
||||
resolution := flag.String("resolution", "", "Target resolution (480p, 720p, 1080p, original)")
|
||||
|
||||
// ... rest of flag definitions ...
|
||||
flag.Parse()
|
||||
|
||||
// ... populate EncodingOptions struct ...
|
||||
opts := EncodingOptions{
|
||||
// ... existing fields ...
|
||||
Resolution: *resolution,
|
||||
// ... rest of fields ...
|
||||
}
|
||||
|
||||
return opts
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Update encodeFile() function to use resolution scaling
|
||||
|
||||
Find the `encodeFile()` function and add resolution scaling integration.
|
||||
|
||||
Look for where the FFmpeg command is being built (likely where video filters are added):
|
||||
|
||||
```go
|
||||
func encodeFile(file string, mode string, opts EncodingOptions) error {
|
||||
// ... existing code ...
|
||||
|
||||
// Build scale filter for resolution preset
|
||||
scaleFilter := ""
|
||||
if opts.Resolution != "" {
|
||||
filter, err := encoding.BuildScaleFilter(file, opts.Resolution)
|
||||
if err != nil {
|
||||
fmt.Printf("⚠️ Warning: Could not build scale filter: %v\n", err)
|
||||
} else if filter != "" {
|
||||
scaleFilter = filter
|
||||
targetHeight := encoding.GetResolutionPresetHeight(opts.Resolution)
|
||||
fmt.Printf("📐 Scaling video to %dp\n", targetHeight)
|
||||
}
|
||||
}
|
||||
|
||||
// ... when building FFmpeg command ...
|
||||
// If scaleFilter is not empty, it should be added to the FFmpeg command
|
||||
// Example: if there's already a video filter section, combine them
|
||||
// or if -vf doesn't exist yet, add the scaleFilter directly
|
||||
|
||||
// ... rest of encodeFile function ...
|
||||
}
|
||||
```
|
||||
|
||||
**Note**: The exact integration point depends on how the FFmpeg command is currently constructed. Look for where other video filters (like odd height handling) are added and follow that pattern.
|
||||
|
||||
### 4. Update printHelp() function
|
||||
|
||||
Find the `printHelp()` function and add documentation for the new flag in the appropriate section:
|
||||
|
||||
```go
|
||||
func printHelp() {
|
||||
// ... existing help text ...
|
||||
|
||||
fmt.Println("\n📐 Resolution Options:")
|
||||
fmt.Println(" --resolution <preset> Scale video to target resolution")
|
||||
fmt.Println(" Options: 480p, 720p, 1080p, original")
|
||||
fmt.Println(" Only scales down, never upscales")
|
||||
fmt.Println(" Maintains aspect ratio")
|
||||
|
||||
// ... rest of help text ...
|
||||
}
|
||||
```
|
||||
|
||||
## Testing the Changes
|
||||
|
||||
After making these changes, rebuild and test:
|
||||
|
||||
```bash
|
||||
# Rebuild
|
||||
make clean
|
||||
make build
|
||||
|
||||
# Test with resolution scaling
|
||||
./build/gwencoder --fast --resolution 720p input_1080p.mp4
|
||||
|
||||
# Test that it doesn't upscale
|
||||
./build/gwencoder --fast --resolution 1080p input_480p.mp4
|
||||
|
||||
# Test original (no scaling)
|
||||
./build/gwencoder --fast --resolution original input.mp4
|
||||
```
|
||||
|
||||
## Expected Output
|
||||
|
||||
When resolution scaling is applied, you should see output like:
|
||||
```
|
||||
📐 Scaling video to 720p
|
||||
```
|
||||
|
||||
When no scaling is needed (input already at or below target):
|
||||
```
|
||||
(no scaling message - continues with encoding)
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
If you encounter issues:
|
||||
|
||||
1. **Build errors**: Check that the `encoding.BuildScaleFilter`, `encoding.GetResolution PresetHeight` functions are being called correctly
|
||||
2. **Runtime errors**: Ensure ffprobe is available and the input file exists
|
||||
3. **No scaling**: Check that the scaleFilter is being added to the actual FFmpeg command
|
||||
|
||||
## Example FFmpeg Command
|
||||
|
||||
The final FFmpeg command should include the scale filter like:
|
||||
```
|
||||
ffmpeg -i input.mp4 -vf scale=-2:720 ... other_args ... output.mkv
|
||||
```
|
||||
|
||||
Where `-2` automatically calculates width based on height while maintaining aspect ratio and ensuring even dimensions.

## Merge Plan for Gwencoder Go Application
|
||||
|
||||
### Phase 1: Core Feature Integration
|
||||
|
||||
**Note on Codec Extensibility**: The architecture is designed to be extensible for future codec support (e.g., x264, VP9, etc.). The `encoding` package uses codec-specific parameter structures (e.g., `AV1AdvancedParams`) that can be extended with similar structures for other codecs. The main encoding pipeline in `encodeFile()` uses codec detection and dispatches to appropriate encoding functions. This modular design allows adding new codecs without major refactoring.
|
||||
|
||||
#### 1.1 AV1 SVT Advanced Parameters
|
||||
**Location**: `gwutils` package or new `encoding` package
|
||||
|
||||
**Future Codec Support**: The structure is designed to allow easy addition of other codec parameter types (e.g., `X264AdvancedParams`, `VP9AdvancedParams`) following the same pattern.
|
||||
|
||||
**New Structures**:
|
||||
```go
|
||||
type AV1AdvancedParams struct {
|
||||
CRF int // Default: 29
|
||||
Preset int // Default: 10
|
||||
Tune int // Default: 0 (VQ)
|
||||
SCD bool // Default: true
|
||||
AQMode int // Default: 2 (DeltaQ)
|
||||
Lookahead int // Default: -1 (auto)
|
||||
EnableTF bool // Default: true
|
||||
Threads int // Default: 0 (auto)
|
||||
Keyint int // Default: -2
|
||||
HierarchicalLevels int // Default: 4

||||
```
|
||||
|
||||
**Integration Points**:
|
||||
- Extend `EncodingMode` struct to include `AV1Advanced *AV1AdvancedParams`
|
||||
- Add resolution detection in `encodeFile()` for CRF adjustment
|
||||
- Build SVT-AV1 parameter string in FFmpeg command construction
|
||||
- Add maxrate cap logic with buffer size calculation
|
||||
|

|
||||
Codec string // "aac" or "opus"
|
||||
SkipIfCompatible bool // Default: true
|
||||
BitratePerChannel int // Default: 80
|
||||
StereoBitrate int // Default: 160
|
||||
ChannelMode string // "preserve", "stereo", "mono"
|
||||
CreateDownmix bool // Default: false
|
||||
DownmixSingleTrack bool // Default: false
|
||||
ForceTranscode bool // Default: false
|
||||
QualityPreset string // "custom", "high_quality", "balanced", "small_size"
|
||||
// Opus-specific
|
||||
OpusApplication string // Default: "audio"
|
||||
OpusVBR string // Default: "on"
|
||||
}
|
||||
```
|
||||
|
||||
**Integration Points**:
|
||||
- Add audio stream analysis using ffprobe
|

|
||||
**Location**: New `streams` package
|
||||
|
||||
**New Structures**:

|
||||
- Add subtitle conversion (ASS/SSA/WebVTT → SRT)
|
||||
- Add subtitle extraction functionality
|
||||
- Integrate ccextractor support (optional dependency)
|
||||
|
||||

## Code Organization Recommendations
|
||||
|
||||
```
|
||||
gwencoder/
|
||||
├── main.go # CLI entry point
|
||||
├── encoding/
|
||||
│ ├── av1.go # AV1 encoding logic
|
||||
│ ├── x264.go # x264 encoding logic (future)
|
||||
│ ├── vp9.go # VP9 encoding logic (future)
|

|
||||
└── ...
|
||||
```
|
||||
|
||||
**Codec Extensibility Pattern**: Each codec gets its own file (e.g., `av1.go`, `x264.go`) with:
|
||||
- Codec-specific parameter struct (e.g., `AV1AdvancedParams`, `X264AdvancedParams`)
|
||||
- Default parameter function (e.g., `DefaultAV1AdvancedParams()`)
|
||||
- Codec-specific build functions (e.g., `BuildSVTParams()`, `BuildX264Params()`)
|
||||
- Codec detection helpers (e.g., `IsAV1Codec()`, `IsX264Codec()`)
|
||||
|
||||
The main `encodeFile()` function uses codec detection to dispatch to the appropriate encoding logic.
|
||||
|
||||
---
|
||||
|
||||
## Migration Notes
|
||||
|
||||
### Backward Compatibility
|
||||
- All existing flags and modes should continue to work
|
||||
- New features should be opt-in via flags
|
||||
- Default behavior should match current implementation
|
||||
|
||||
### Codec Extensibility
|
||||
- Architecture supports adding new codecs (x264, VP9, etc.) without major refactoring
|
||||
- Each codec follows the same pattern: parameter struct, default function, build functions
|
||||
- Codec detection in `encodeFile()` dispatches to appropriate encoding logic
|
||||
- Future codecs can be added by:
|
||||
1. Creating new file (e.g., `encoding/x264.go`)
|
||||
2. Defining codec-specific parameter struct
|
||||
3. Implementing codec-specific build functions
|
||||
4. Adding codec detection in main encoding pipeline
|
||||
5. Adding CLI flags for codec-specific options
|
||||
|
||||
### Dependencies
|
||||
- No new external dependencies required (uses existing ffmpeg/ffprobe)
|
||||
- Optional: ccextractor for CC extraction (can be skipped if not available)
|
||||
|
||||
### Performance Considerations
|
||||
- Stream analysis adds minimal overhead (single ffprobe call)
|
||||
- Advanced AV1 features may slow encoding (expected)
|
||||
- Audio processing overhead is minimal
|
||||
|
||||

|
||||
|
||||
## Summary
|
||||
|
||||
The three Tdarr plugins provide:
|
||||
1. **Advanced AV1 encoding** with quality/speed controls
|
||||
2. **Comprehensive audio standardization** with codec/channel/bitrate options
|
||||
3. **Stream management** with reordering and subtitle handling
|
||||
|
||||
These features can be integrated into Gwencoder while maintaining its simple CLI interface and adding powerful options for advanced users. The modular design allows incremental implementation and testing.

# Troubleshooting Guide
|
||||
|
||||
Common issues and solutions for GWEncoder.
|
||||
|
||||
## Installation Issues
|
||||
|
||||
### FFmpeg Not Found
|
||||
|
||||
**Error**:
|
||||
```
|
||||
❌ FFmpeg: Not available
|
||||
```
|
||||
|
||||
**Solution**:
|
||||
1. Install FFmpeg for your system:
|
||||
- **Linux**: `sudo apt install ffmpeg` (Debian/Ubuntu) or `sudo yum install ffmpeg` (RHEL/CentOS)
|
||||
- **macOS**: `brew install ffmpeg`
|
||||
- **Windows**: Download from [ffmpeg.org](https://ffmpeg.org/download.html)
|
||||
2. Ensure FFmpeg is in your PATH
|
||||
3. Verify installation: `ffmpeg -version`
|
||||
|
||||
### FFprobe Not Found
|
||||
|
||||
**Error**:
|
||||
```
|
||||
❌ FFprobe: Not available
|
||||
```
|
||||
|
||||
**Solution**:
|
||||
- FFprobe is typically included with FFmpeg
|
||||
- If missing, install FFmpeg (see above)
|
||||
- Verify: `ffprobe -version`
|
||||
|
||||
### ccextractor Not Found
|
||||
|
||||
**Warning**:
|
||||
```
|
||||
⚠️ ccextractor not available in PATH, skipping CC extraction
|
||||
```
|
||||
|
||||
**Solution**:
|
||||
- This is optional - CC extraction will be skipped if ccextractor is unavailable
|
||||
- To enable CC extraction:
|
||||
- **Linux**: `sudo apt install ccextractor` or compile from source
|
||||
- **macOS**: `brew install ccextractor`
|
||||
- **Windows**: Download from [ccextractor.org](https://ccextractor.org/)
|
||||
- Verify: `ccextractor -version`
|
||||
|
||||
## Encoding Issues
|
||||
|
||||
### Odd Video Height Error
|
||||
|
||||
**Error**:
|
||||
```
|
||||
Error: Source Height must be even for YUV_420 colorspace
|
||||
```
|
||||
|
||||
**Solution**:
|
||||
- **Automatically handled** - GWEncoder detects and adjusts odd heights
|
||||
- The height is automatically rounded to the nearest even number
|
||||
- No user action required
|
||||
|
||||
### Unsupported Streams in MKV
|
||||
|
||||
**Warning**:
|
||||
```
|
||||
⚠️ Filtered X unsupported stream(s) for MKV compatibility
|
||||
```
|
||||
|
||||
**Solution**:
|
||||
- **Automatically handled** - Unsupported streams are filtered for MKV output
|
||||
- Streams like EIA-608, CC_DEC, tx3g are incompatible with MKV
|
||||
- Container is automatically switched to MP4 if needed
|
||||
- No user action required
|
||||
|
||||
### Container Switch Notification
|
||||
|
||||
**Message**:
|
||||
```
|
||||
📦 Switching to MP4 container for compatibility (Apple/broadcast streams detected)
|
||||
```
|
||||
|
||||
**Explanation**:
|
||||
- GWEncoder automatically switches to MP4 when:
|
||||
- Input is Apple/broadcast format (MP4/MOV)
|
||||
- Unsupported subtitle streams are detected
|
||||
- This prevents muxing errors
|
||||
- No user action required
|
||||
|
||||
### Encoding Fails with "Stream map matches no streams"
|
||||
|
||||
**Error**:
|
||||
```
|
||||
Stream map '' matches no streams
|
||||
```
|
||||
|
||||
**Solution**:
|
||||
- Usually caused by missing audio streams
|
||||
- GWEncoder handles this automatically with optional mapping (`-map 0:a?`)
|
||||
- If issue persists, check input file with: `ffprobe input.mp4`
|
||||
|
||||
### Low Encoding Speed
|
||||
|
||||
**Issue**: Encoding is very slow
|
||||
|
||||
**Solutions**:
|
||||
1. **Use faster preset**:
|
||||
```bash
|
||||
./gwencoder --fast --av1-preset 12
|
||||
```
|
||||
|
||||
2. **Disable advanced features**:
|
||||
```bash
|
||||
./gwencoder --fast --av1-disable-tf --av1-disable-scd --av1-disable-aq
|
||||
```
|
||||
|
||||
3. **Use hardware acceleration** (if available):
|
||||
```bash
|
||||
./gwencoder --fast --nvhevc
|
||||
```
|
||||
|
||||
4. **Use lower quality**:
|
||||
```bash
|
||||
./gwencoder --fast --av1-crf 35
|
||||
```
|
||||
|
||||
## Audio Issues
|
||||
|
||||
### Opus Incompatible Layout
|
||||
|
||||
**Warning**:
|
||||
```
|
||||
🔊 Converting incompatible layout to stereo for Opus compatibility
|
||||
```
|
||||
|
||||
**Explanation**:
|
||||
- Some channel layouts are incompatible with Opus
|
||||
- GWEncoder automatically converts to stereo
|
||||
- No user action required
|
||||
|
||||
### Audio Codec Mismatch
|
||||
|
||||
**Issue**: Audio codec doesn't match container
|
||||
|
||||
**Solution**:
|
||||
- GWEncoder automatically selects compatible codec:
|
||||
- MP4 → AAC
|
||||
- MKV/WEBM → Opus
|
||||
- Force specific codec if needed:
|
||||
```bash
|
||||
./gwencoder --fast --audio-codec aac # Force AAC
|
||||
./gwencoder --fast --audio-codec opus # Force Opus
|
||||
```
|
||||
|
||||
## Subtitle Issues
|
||||
|
||||
### Subtitle Extraction Fails
|
||||
|
||||
**Issue**: Subtitles not extracted
|
||||
|
||||
**Solutions**:
|
||||
1. Check if subtitles exist in input:
|
||||
```bash
|
||||
ffprobe -v error -select_streams s -show_entries stream=codec_name input.mp4
|
||||
```
|
||||
|
||||
2. Ensure extraction flag is set:
|
||||
```bash
|
||||
./gwencoder --fast --extract-subs
|
||||
```
|
||||
|
||||
3. Check file permissions in output directory
|
||||
|
||||
### Subtitle Conversion Issues
|
||||
|
||||
**Issue**: Subtitles not converted to SRT
|
||||
|
||||
**Solutions**:
|
||||
1. Only text-based subtitles can be converted (ASS, SSA, WebVTT)
|
||||
2. Image subtitles (PGS, VobSub) are copied, not converted
|
||||
3. Enable conversion explicitly:
|
||||
```bash
|
||||
./gwencoder --fast --convert-subs-srt
|
||||
```
|
||||
|
||||
## Performance Issues
|
||||
|
||||
### High CPU Usage
|
||||
|
||||
**Issue**: Encoding uses 100% CPU
|
||||
|
||||
**Explanation**:
|
||||
- This is normal for software encoding
|
||||
- AV1 encoding is CPU-intensive
|
||||
- Use hardware acceleration if available (`--nvhevc`)
|
||||
|
||||
### Large Output Files
|
||||
|
||||
**Issue**: Output file is larger than input
|
||||
|
||||
**Solutions**:
|
||||
1. **Use higher CRF** (lower quality, smaller files):
|
||||
```bash
|
||||
./gwencoder --fast --av1-crf 35
|
||||
```
|
||||
|
||||
2. **Use maximum compression mode**:
|
||||
```bash
|
||||
./gwencoder --tiny
|
||||
```
|
||||
|
||||
3. **Set bitrate cap**:
|
||||
```bash
|
||||
./gwencoder --fast --av1-maxrate 5000
|
||||
```
|
||||
|
||||
4. **Use lower audio quality**:
|
||||
```bash
|
||||
./gwencoder --fast --audio-quality small
|
||||
```
|
||||
|
||||
### Slow Encoding Speed
|
||||
|
||||
**Issue**: Encoding takes too long
|
||||
|
||||
**Solutions**:
|
||||
1. **Use faster preset**:
|
||||
```bash
|
||||
./gwencoder --fast --av1-preset 12
|
||||
```
|
||||
|
||||
2. **Disable quality features**:
|
||||
```bash
|
||||
./gwencoder --fast --av1-disable-tf --av1-disable-scd
|
||||
```
|
||||
|
||||
3. **Use hardware acceleration**:
|
||||
```bash
|
||||
./gwencoder --fast --nvhevc
|
||||
```
|
||||
|
||||
4. **Use faster mode**:
|
||||
```bash
|
||||
./gwencoder --fast # Instead of --hq or --slow
|
||||
```
|
||||
|
||||
## Quality Issues
|
||||
|
||||
### Poor Video Quality
|
||||
|
||||
**Issue**: Output quality is too low
|
||||
|
||||
**Solutions**:
|
||||
1. **Use lower CRF** (higher quality):
|
||||
```bash
|
||||
./gwencoder --hq --av1-crf 22
|
||||
```
|
||||
|
||||
2. **Use slower preset** (better quality):
|
||||
```bash
|
||||
./gwencoder --hq --av1-preset 4
|
||||
```
|
||||
|
||||
3. **Enable all quality features**:
|
||||
```bash
|
||||
./gwencoder --hq # Don't disable TF/SCD/AQ
|
||||
```
|
||||
|
||||
4. **Use high quality mode**:
|
||||
```bash
|
||||
./gwencoder --hq # Or --slow for best quality
|
||||
```
|
||||
|
||||
### Poor Audio Quality
|
||||
|
||||
**Issue**: Audio quality is too low
|
||||
|
||||
**Solutions**:
|
||||
1. **Use high quality preset**:
|
||||
```bash
|
||||
./gwencoder --fast --audio-quality high
|
||||
```
|
||||
|
||||
2. **Set custom bitrate**:
|
||||
```bash
|
||||
./gwencoder --fast --audio-bitrate-per-ch 128
|
||||
```
|
||||
|
||||
3. **Preserve original channels**:
|
||||
```bash
|
||||
./gwencoder --fast --audio-preserve
|
||||
```
|
||||
|
||||
## File Format Issues
|
||||
|
||||
### Unsupported Input Format
|
||||
|
||||
**Error**: File cannot be read
|
||||
|
||||
**Solution**:
|
||||
- GWEncoder supports: WMV, AVI, MP4, MKV, MPG, TS, WEBM
|
||||
- Convert unsupported formats first using FFmpeg
|
||||
- Check file with: `ffprobe input.file`
|
||||
|
||||
### Output Format Issues
|
||||
|
||||
**Issue**: Output file doesn't play
|
||||
|
||||
**Solutions**:
|
||||
1. **Try different container**:
|
||||
```bash
|
||||
./gwencoder --web # Uses WEBM
|
||||
./gwencoder --fast # Uses MKV
|
||||
```
|
||||
|
||||
2. **Use MP4 for compatibility**:
|
||||
```bash
|
||||
./gwencoder --tiny # Uses MP4
|
||||
```
|
||||
|
||||
3. **Check codec compatibility**:
|
||||
- Use H.264 for maximum compatibility: `--x264`
|
||||
- Use AV1 for modern players (default)
|
||||
|
||||
## Getting Help
|
||||
|
||||
### Check System Information

# Phase 4 Implementation Complete ✅
|
||||
|
||||
## Overview
|
||||
|
||||
Phase 4 implements the remaining missing features from Tdarr plugins, focusing on unsupported stream exclusion, container smart selection improvements, and CC extraction.
|
||||
|
||||
## ✅ Implemented Features
|
||||
|
||||
### 1. Unsupported Stream Exclusion ✅
|
||||
|
||||
**Status**: Fully Implemented
|
||||
**Location**: `encoding/streams.go`, `main.go`
|
||||
|
||||
**Changes**:
|
||||
- Added `FilterUnsupportedStreams()` function to filter unsupported streams before mapping
|
||||
- Unsupported streams are now filtered **before** reordering and mapping (not after)
|
||||
- Only filters when outputting to MKV (MP4 can handle these streams)
|
||||
- Improved logging to show how many streams were filtered
|
||||
|
||||
**How it works**:
|
||||
1. Analyze all streams from input file
|
||||
2. Filter out unsupported subtitle streams (EIA-608, CC_DEC, tx3g) if outputting to MKV
|
||||
3. Reorder remaining streams (English first)
|
||||
4. Build mapping arguments from filtered/reordered streams
|
||||
|
||||
**Impact**:
|
||||
- **Time**: Minimal (one-time filtering)
|
||||
- **Compression**: None
|
||||
- **File Size**: Slightly smaller (removed streams)
|
||||
- **Quality**: None
|
||||
- **Functionality**: Prevents muxing errors with problematic streams in MKV
|
||||
|
||||
**Code Changes**:
|
||||
- `encoding/streams.go`: Added `FilterUnsupportedStreams()` function
|
||||
- `main.go`: Updated stream processing to filter before reordering
|
||||
|
||||
---
|
||||
|
||||
### 2. Container Smart Selection Improvements ✅
|
||||
|
||||
**Status**: Enhanced and Verified
|
||||
**Location**: `encoding/streams.go`, `main.go`
|
||||
|
||||
**Improvements**:
|
||||
- Better detection of Apple/broadcast formats
|
||||
- Improved logging when container is switched
|
||||
- Integration with unsupported stream detection
|
||||
- Works with all encoding modes
|
||||
|
||||
**How it works**:
|
||||
1. Detect input container format using `GetContainerFormat()`
|
||||
2. Check for unsupported streams using `DetectUnsupportedStreams()`
|
||||
3. If MKV requested but has unsupported streams or Apple format, switch to MP4
|
||||
4. Log container switch with reason
|
||||
|
||||
**Impact**:
|
||||
- **Time**: None
|
||||
- **Compression**: None
|
||||
- **File Size**: None
|
||||
- **Quality**: None
|
||||
- **Functionality**: Prevents errors with Apple/broadcast streams
|
||||
|
||||

|
||||
|
||||
### 3. CC Extraction (ccextractor) ✅
|
||||
|
||||
**Status**: Fully Implemented
|
||||
**Location**: `encoding/streams.go`, `main.go`
|
||||
|
||||
**Features**:
|
||||
- Detects closed caption streams (EIA-608, CC_DEC)
|
||||
- Extracts CC to external `.cc.srt` file using `ccextractor`
|
||||
- Optional embedding of extracted CC as subtitle track
|
||||
- Checks for `ccextractor` availability in PATH
|
||||
- Skips extraction if output file already exists
|
||||
|
||||
**New Functions**:
|
||||
- `IsClosedCaption()` - Detects CC streams by codec name/tag
|
||||
- `GetCCStreams()` - Returns CC streams from stream list
|
||||
- `CheckCCExtractorAvailable()` - Checks if ccextractor is in PATH
|
||||
- `ExtractCC()` - Runs ccextractor to extract CC to SRT
|
||||
- `GetCCOutputPath()` - Generates output path for CC file
|
||||
- `BuildCCEmbedArgs()` - Builds FFmpeg args to embed extracted CC
|
||||
|
||||
**CLI Flags**:
|
||||
- `--use-cc-extractor` - Enable CC extraction
|
||||
- `--embed-extracted-cc` - Embed extracted CC as subtitle track
|
||||
|
||||
**How it works**:
|
||||
1. Analyze streams to detect CC streams
|
||||
2. If `--use-cc-extractor` is set and ccextractor is available:
|
||||
- Extract CC streams to `{basename}.cc.srt`
|
||||
- Log extraction result
|
||||
3. If `--embed-extracted-cc` is set:
|
||||
- Add extracted SRT as input to FFmpeg
|
||||
- Map it as a subtitle stream
|
||||
|
||||
**Impact**:
|
||||
- **Time**: +5-10s per file with CC streams
|
||||
- **Compression**: None
|
||||
- **File Size**: +50-200KB (external SRT file)
|
||||
- **Quality**: None
|
||||
- **Functionality**: Extracts closed captions for accessibility
|
||||
|
||||
**Dependencies**:
|
||||
- `ccextractor` binary (optional, checked at runtime)
|
||||
- Gracefully handles missing ccextractor with warning
|
||||
|
||||
**Code Changes**:
|
||||
- `encoding/streams.go`: Added CC detection and extraction functions
|
||||
- `main.go`: Added CC extraction logic before encoding
|
||||
- `main.go`: Added CLI flags for CC extraction
|
||||
- `main.go`: Added CC embedding logic
|
||||
- `main.go`: Updated help text
|
||||
|
||||
---
|
||||
|
||||
### 4. StreamInfo Enhancement ✅
|
||||
|
||||
**Status**: Enhanced
|
||||
**Location**: `encoding/streams.go`
|
||||
|
||||
**Changes**:
|
||||
- Added `CodecTag` field to `StreamInfo` struct
|
||||
- Updated `AnalyzeStreams()` to extract codec tag information
|
||||
- Enables better CC detection (checks both codec name and tag)
|
||||
|
||||
**Why**:
|
||||
- Some CC streams are identified by codec tag (`cc_dec`) rather than codec name
|
||||
- Improves detection accuracy for closed captions
|
||||

### Phase 4: Missing Features
|
||||
|
||||
#### 4.1 CC Extraction (ccextractor) ⏳
|
||||
**Status**: NOT Implemented
|
||||
**Priority**: Low
|
||||
**Impact**:
|
||||
- **Time**: +5-10s per file with CC streams
|
||||
- **Compression**: None
|
||||
- **File Size**: +50-200KB (external SRT file)
|
||||
- **Quality**: None
|
||||
- **Functionality**: Extracts EIA-608/teletext captions to external SRT
|
||||
|
||||
**Details**:
|
||||
- Requires `ccextractor` binary (optional dependency)
|
||||
- Extracts closed captions from video streams
|
||||
- Creates external `.cc.srt` file
|
||||
- Optional: Embed extracted CC back into container
|
||||
|
||||
**Implementation Needed**:
|
||||
- Add `--use-cc-extractor` flag
|
||||
- Add `--embed-extracted-cc` flag
|
||||
- Implement `ExtractCC()` function in `encoding/streams.go`
|
||||
- Check for `ccextractor` availability
|
||||
- Run `ccextractor` before FFmpeg encoding
|
||||
- Optionally embed extracted SRT back into output
|
||||
|
||||
**Files to Modify**:

||||
|
||||
**Details**:
|
||||
- Excludes: EIA-608, CC_DEC, tx3g, bin_data streams
|
||||
- Only applies when outputting to MKV
|
||||
- MP4 can handle these streams
|
||||
|
||||
**Current Status**:
|
||||
- ✅ `DetectUnsupportedStreams()` exists in `encoding/streams.go`
|
||||
- ✅ `IsUnsupportedSubtitle()` exists
|
||||
- ⏳ Exclusion logic in FFmpeg command building needs verification
|
||||
- ⏳ Stream mapping needs to skip unsupported streams when outputting to MKV
|
||||
|
||||
**Implementation Needed**:
|
||||
- Verify unsupported streams are excluded from `-map` arguments when outputting to MKV
|
||||
- Add logging when streams are excluded
|
||||
- Test with files containing unsupported streams
|
||||
|
||||
**Files to Check/Modify**:
|
||||
- `main.go` - Verify stream mapping excludes unsupported streams for MKV output

**High Priority** (Do Next):
|
||||
1. Comprehensive testing with various flag combinations
|
||||
2. Verify unsupported stream exclusion works correctly
|
||||
3. Test container smart selection with real files
|
||||
|
||||
**Medium Priority**:
|
||||
4. Performance benchmarking
|
||||
5. Documentation updates
|
||||
6. Logging enhancements
|
||||
7. Error handling improvements
|
||||
|
||||
**Low Priority**:
|
||||
8. CC extraction (ccextractor) implementation
|
||||
9. Advanced logging features
|
||||
|
||||
---
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Immediate**: Run comprehensive tests with `testvid.webm` and various flag combinations
|
||||
2. **Short-term**: Verify unsupported stream exclusion and container selection
|
||||
3. **Medium-term**: Performance benchmarking and documentation
|
||||
4. **Long-term**: CC extraction (if needed)

# Plan Updates Summary
|
||||
|
||||
## Changes Made
|
||||
|
||||
### 1. Added Force Transcode Flag ✅
|
||||
|
||||
**Location**: `TDARR_MERGE_PLAN.md` - Phase 2, Section 2.1
|
||||
|
||||
Added `--force-transcode` flag to the AV1 advanced features section:
|
||||
|
||||
```bash
|
||||
--force-transcode # Force transcoding even if file is already in target codec
|
||||
```
|
||||
|
||||
**Status**:
|
||||
- ✅ Added to plan
|
||||
- ⏳ Implementation pending (will be added in Phase 2)
|
||||
- ✅ Code structure ready (ForceTranscode field exists in AV1AdvancedParams)
|
||||
|
||||
### 2. Codec Extensibility Architecture ✅
|
||||
|
||||
**New Document**: `CODEC_EXTENSIBILITY.md`
|
||||
|
||||
Created comprehensive documentation on how to add future codecs (x264, VP9, etc.):
|
||||
|
||||
- **Architecture Pattern**: Each codec follows the same modular pattern
|
||||
- **Step-by-Step Guide**: How to add a new codec
|
||||
- **Example Code**: x264 implementation example
|
||||
- **Integration Points**: How codecs integrate into main pipeline
|
||||
|
||||
**Key Points**:
|
||||
- Each codec gets its own file (e.g., `encoding/x264.go`)
|
||||
- Codec-specific parameter structs (e.g., `X264AdvancedParams`)
|
||||
- Shared infrastructure (audio, streams) works for all codecs
|
||||
- Main pipeline uses codec detection to dispatch
|
||||
|
||||
**Updated Files**:
|
||||
- `TDARR_MERGE_PLAN.md` - Added extensibility notes
|
||||
- `CODEC_EXTENSIBILITY.md` - New comprehensive guide
|
||||
|
||||
### 3. Updated Code Organization ✅
|
||||
|
||||
**Location**: `TDARR_MERGE_PLAN.md` - Code Organization section
|
||||
|
||||
Updated to show future codec files:
|
||||
```
|
||||
encoding/
|
||||
├── av1.go # AV1 encoding logic
|
||||
├── x264.go # x264 encoding logic (future)
|
||||
├── vp9.go # VP9 encoding logic (future)
|
||||
```
|
||||
|
||||
Added extensibility pattern documentation.
|
||||
|
||||
### 4. Updated Implementation Priority ✅
|
||||
|
||||
**Location**: `TDARR_MERGE_PLAN.md` - Implementation Priority
|
||||
|
||||
Added force transcode flag to high priority:
|
||||
```
|
||||
5. ⏳ Force transcode flag (`--force-transcode`)
|
||||
```
|
||||
|
||||
### 5. Code Cleanup ✅
|
||||
|
||||
**Location**: `main.go`
|
||||
|
||||
Removed hardcoded `ForceTranscode = true` and added comment:
|
||||
```go
|
||||
// ForceTranscode will be set via CLI flag (--force-transcode) when implemented
|
||||
// Default: false (skip files already in target codec)
|
||||
```
|
||||
|
||||
## Architecture Benefits
|
||||
|
||||
### Modularity
|
||||
- Each codec is self-contained
|
||||
- Easy to add new codecs without refactoring
|
||||
|
||||
### Consistency
|
||||
- All codecs follow the same pattern
|
||||
- Shared infrastructure (audio, streams)
|
||||
|
||||
### Future-Proof
|
||||
- Ready for x264, VP9, HEVC, etc.
|
||||
- Clear path for implementation
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Implement `--force-transcode` flag** (Phase 2)
|
||||
- Add flag parsing in `main.go`
|
||||
- Pass to `AV1AdvancedParams`
|
||||
- Test with existing AV1 files
|
||||
|
||||
2. **Future Codec Implementation** (When needed)
|
||||
- Follow pattern in `CODEC_EXTENSIBILITY.md`
|
||||
- Create codec-specific file
|
||||
- Integrate into main pipeline
|
||||
|
||||
## Files Modified
|
||||
|
||||
- ✅ `TDARR_MERGE_PLAN.md` - Updated with force transcode flag and extensibility notes
|
||||
- ✅ `CODEC_EXTENSIBILITY.md` - New comprehensive guide
|
||||
- ✅ `main.go` - Removed hardcoded force transcode, added comment
|
||||
|
||||
## Files Created

# Codec Extensibility Architecture
|
||||
|
||||
## Overview
|
||||
|
||||
The Gwencoder architecture is designed to be extensible for future codec support. The current implementation focuses on AV1, but the structure allows easy addition of other codecs (x264, VP9, HEVC, etc.) without major refactoring.
|
||||
|
||||
## Architecture Pattern
|
||||
|
||||
### Current Implementation (AV1)
|
||||
|
||||
```
|
||||
encoding/
|
||||
├── av1.go # AV1-specific logic
|
||||
│ ├── AV1AdvancedParams struct
|
||||
│ ├── DefaultAV1AdvancedParams()
|
||||
│ ├── BuildSVTParams()
|
||||
│ ├── BuildAV1QualityArgs()
|
||||
│ └── IsAV1Codec()
|
||||
```
|
||||
|
||||
### Pattern for Adding New Codecs
|
||||
|
||||
To add a new codec (e.g., x264), follow this pattern:
|
||||
|
||||
1. **Create codec-specific file**: `encoding/x264.go`
|
||||
|
||||
2. **Define parameter struct**:
|
||||
```go
|
||||
type X264AdvancedParams struct {
|
||||
CRF int // Default: 23
|
||||
Preset string // Default: "medium"
|
||||
Tune string // Default: "film"
|
||||
Profile string // Default: "high"
|
||||
Level string // Default: "4.1"
|
||||
ForceTranscode bool // Default: false
|
||||
// ... other x264-specific params
|
||||
}
|
||||
```
|
||||
|
||||
3. **Implement default function**:
|
||||
```go
|
||||
func DefaultX264AdvancedParams() X264AdvancedParams {
|
||||
return X264AdvancedParams{
|
||||
CRF: 23,
|
||||
Preset: "medium",
|
||||
Tune: "film",
|
||||
Profile: "high",
|
||||
Level: "4.1",
|
||||
ForceTranscode: false,
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
4. **Implement build functions**:
|
||||
```go
|
||||
func BuildX264Params(params X264AdvancedParams) string {
|
||||
// Build x264 parameter string
|
||||
}
|
||||
|
||||
func BuildX264QualityArgs(params X264AdvancedParams, finalCRF int) (string, string) {
|
||||
// Build FFmpeg quality arguments
|
||||
}
|
||||
```
|
||||
|
||||
5. **Add codec detection**:
|
||||
```go
|
||||
func IsX264Codec(codec string) bool {
|
||||
codec = strings.ToLower(codec)
|
||||
return codec == "h264" || codec == "libx264"
|
||||
}
|
||||
```
|
||||
|
||||
6. **Integrate into main pipeline**:
|
||||
- Add codec detection in `encodeFile()`
|
||||
- Dispatch to x264 encoding logic when detected
|
||||
- Use same audio/stream handling infrastructure
|
||||
|
||||
## Integration Points
|
||||
|
||||
### Main Encoding Function
|
||||
|
||||
The `encodeFile()` function uses codec detection to dispatch:
|
||||
|
||||
```go
|
||||
if useX264 {
|
||||
// Use x264 encoding logic
|
||||
x264Params := encoding.DefaultX264AdvancedParams()
|
||||
// ... configure x264 params
|
||||
// ... build x264 FFmpeg args
|
||||
} else if useNVHEVC {
|
||||
// Use NVENC HEVC logic (existing)
|
||||
} else {
|
||||
// Use AV1 encoding logic (current implementation)
|
||||
av1Params := encoding.DefaultAV1AdvancedParams()
|
||||
// ... configure AV1 params
|
||||
// ... build AV1 FFmpeg args
|
||||
}
|
||||
```
|
||||
|
||||
### Shared Infrastructure
|
||||
|
||||
All codecs share:
|
||||
- **Audio standardization**: `encoding/audio.go` (codec-agnostic)
|
||||
- **Stream reordering**: `encoding/streams.go` (codec-agnostic)
|
||||
- **Subtitle handling**: `encoding/streams.go` (codec-agnostic)
|
||||
- **Resolution detection**: Can be shared or codec-specific
|
||||
|
||||
## Future Codec Support
|
||||
|
||||
### Planned Codecs (Not Yet Implemented)
|
||||
|
||||
1. **x264/H.264**
|
||||
- File: `encoding/x264.go`
|
||||
- Parameters: CRF, preset, tune, profile, level
|
||||
- Uses: `libx264` encoder
|
||||
|
||||
2. **VP9**
|
||||
- File: `encoding/vp9.go`
|
||||
- Parameters: CRF, speed, tile-columns, etc.
|
||||
- Uses: `libvpx-vp9` encoder
|
||||
|
||||
3. **HEVC (Software)**
|
||||
- File: `encoding/hevc.go`
|
||||
- Parameters: CRF, preset, etc.
|
||||
- Uses: `libx265` encoder
|
||||
|
||||
### Adding a New Codec: Step-by-Step
|
||||
|
||||
1. **Create codec file**: `encoding/{codec}.go`
|
||||
2. **Define parameter struct** with codec-specific options
|
||||
3. **Implement default parameters** function
|
||||
4. **Implement build functions** for FFmpeg arguments
|
||||
5. **Add codec detection** helpers
|
||||
6. **Add CLI flags** for codec-specific options (optional)
|
||||
7. **Integrate into `encodeFile()`** with codec detection
|
||||
8. **Test** with sample files
|
||||
|
||||
## Benefits of This Architecture
|
||||
|
||||
1. **Modularity**: Each codec is self-contained
|
||||
2. **Maintainability**: Easy to update codec-specific logic
|
||||
3. **Extensibility**: New codecs don't require refactoring existing code
|
||||
4. **Shared Infrastructure**: Audio/stream handling works for all codecs
|
||||
5. **Consistent Interface**: All codecs follow the same pattern
|
||||
|
||||
## Example: Adding x264 Support (Future)
|
||||
|
||||
```go
|
||||
// encoding/x264.go
|
||||
package encoding
|
||||
|
||||
type X264AdvancedParams struct {
|
||||
CRF int
|
||||
Preset string
|
||||
Tune string
|
||||
Profile string
|
||||
Level string
|
||||
ForceTranscode bool
|
||||
}
|
||||
|
||||
func DefaultX264AdvancedParams() X264AdvancedParams {
|
||||
return X264AdvancedParams{
|
||||
CRF: 23,
|
||||
Preset: "medium",
|
||||
Tune: "film",
|
||||
Profile: "high",
|
||||
Level: "4.1",
|
||||
ForceTranscode: false,
|
||||
}
|
||||
}
|
||||
|
||||
func BuildX264Args(params X264AdvancedParams) []string {
|
||||
args := []string{
|
||||
"-c:v", "libx264",
|
||||
"-crf", strconv.Itoa(params.CRF),
|
||||
"-preset", params.Preset,
|
||||
"-tune", params.Tune,
|
||||
"-profile:v", params.Profile,
|
||||
"-level", params.Level,
|
||||
}
|
||||
return args
|
||||
}
|
||||
```
|
||||
|
||||
Then in `main.go`:
|
||||
```go
|
||||
if useX264 {
|
||||
x264Params := encoding.DefaultX264AdvancedParams()
|
||||
// Configure from mode or CLI flags
|
||||
x264Args := encoding.BuildX264Args(x264Params)
|
||||
args = append(args, x264Args...)
|
||||
}
|
||||
```
|
||||
|
||||
## Notes
|
||||
|
||||
- **Force Transcode**: All codecs should support `ForceTranscode` flag
|
||||
- **Codec Detection**: Use `GetVideoCodec()` to detect input codec
|
||||
- **Skip Logic**: Each codec can implement its own skip logic
|
||||
- **CLI Flags**: Codec-specific flags should follow pattern: `--{codec}-{option}`

# Defaults Comparison: Tdarr vs GWEncoder
|
||||
|
||||
## ⚠️ UPDATE: Default Transcoding Behavior
|
||||
|
||||
**GWEncoder Default Behavior (Updated)**:
|
||||
- ✅ **All codecs EXCEPT AV1 are transcoded by default** (H.264, HEVC, VP8, VP9, etc.)
|
||||
- ⏭️ **AV1 files are skipped by default** (use `--force` or `--force-transcode` to transcode them)
|
||||
- 🔄 **HEVC files are now transcoded by default** (SkipHEVC default changed from `true` to `false`)
|
||||
|
||||
This differs from Tdarr's behavior where HEVC files are skipped by default.
|
||||
|
||||

# Defaults Comparison: Tdarr vs GWEncoder
|
||||
|
||||
## AV1 Advanced Parameters
|

| SCD (Scene Change Detection) | 1 (enabled) | true (enabled) | ✅ |
|
||||
| AQ Mode (Adaptive Quantization) | 2 (DeltaQ) | 2 (DeltaQ) | ✅ |
|
||||
| Lookahead | -1 (auto) | -1 (auto) | ✅ |
|
||||
| Enable TF (Temporal Filtering) | 1 (enabled) | true (enabled) | ✅ |
|

|
||||
|
||||
**Result**: ✅ **All AV1 defaults match**
|
||||
|
||||

|
||||
|
||||
## Audio Standardization
|
||||
|
||||
| Parameter | Tdarr Default | GWEncoder Default | Match |
|
||||
|-----------|---------------|-------------------|-------|
|
||||
| Codec | "aac" | "opus" | ❌ **MISMATCH** |
|
||||
| Skip If Compatible | "true" | true | ✅ |
|
||||
| Bitrate Per Channel | "80" | 80 | ✅ |
|
||||
| Stereo Bitrate | "160" | 160 | ✅ |
|
||||
| Channel Mode | "preserve" | "preserve" | ✅ |
|
||||
| Create Downmix | "false" | false | ✅ |
|
||||
| Downmix Single Track | "false" | false | ✅ |
|
||||
| Force Transcode | "false" | false | ✅ |
|
||||
| Opus Application | "audio" | "audio" | ✅ |
|
||||
| Opus VBR | "on" | "on" | ✅ |
|
||||
| Quality Preset | "custom" | "custom" | ✅ |
|
||||
|
||||
**Result**: ❌ **One mismatch - Codec default**
|
||||
|
||||
**Issue**:
|
||||
- Tdarr defaults to **AAC**
|
||||
- GWEncoder defaults to **Opus**
|
||||
|
||||
**Reason for GWEncoder choice**:
|
||||
- GWEncoder uses container-based codec selection by default
|
||||
- Opus is used for MKV/WEBM (most modes)
|
||||
- AAC is used for MP4 (when needed)
|
||||
- This provides better compression while maintaining compatibility
|
||||
|
||||
**Recommendation**:
|
||||
- GWEncoder's approach is more flexible (container-aware)
|
||||
- If exact Tdarr parity is needed, default should be "aac"
|
||||
- Current behavior is intentional for better compression
|
||||
|
||||

|
||||
|
||||
## Stream Reordering
|
||||
|
||||
| Parameter | Tdarr Default | GWEncoder Default | Match |
|
||||
|-----------|---------------|-------------------|-------|
|
||||
| Include Audio | "Yes" (true) | true | ✅ |
|
||||
| Include Subtitles | "Yes" (true) | true | ✅ |
|
||||
| Standardize To SRT | "Yes" (true) | true | ✅ |
|
||||
| Extract Subtitles | "No" (false) | false | ✅ |
|
||||
| Remove After Extract | "No" (false) | false | ✅ |
|
||||
| Skip Commentary | "Yes" (true) | true | ✅ |
|
||||
| Custom Language Codes | "eng,en,english,en-us,en-gb,en-ca,en-au" | ["eng", "en", "english", "en-us", "en-gb", "en-ca", "en-au"] | ✅ |
|
||||
| Use CC Extractor | "No" (false) | false | ✅ |
|
||||
| Embed Extracted CC | "No" (false) | false | ✅ |
|
||||
|
||||
**Result**: ✅ **All stream reordering defaults match**
|
||||
|
||||
---
|
||||
|
||||
## Summary
|
||||
|
||||
### ✅ Matches (2/3 categories)
|
||||
- **AV1 Advanced Parameters**: 100% match
|
||||
- **Stream Reordering**: 100% match
|
||||
|
||||
### ❌ Mismatch (1/3 categories)
|
||||
- **Audio Standardization**: 1 mismatch (codec default)
|
||||
|
||||
### Overall: 95% Match
|
||||
|
||||
---
|
||||
|
||||
## Recommendation
|
||||
|
||||
The only difference is the audio codec default:
|
||||
- **Tdarr**: Always defaults to AAC
|
||||
- **GWEncoder**: Defaults to Opus (with container-aware fallback to AAC for MP4)
|
||||
|
||||
**Options**:
|
||||
1. **Keep current behavior** (recommended) - Better compression, container-aware
|
||||
2. **Change to match Tdarr** - Default to AAC for exact parity
|
||||
|
||||
**Current behavior is intentional** because:
|
||||
- Opus provides better compression (smaller files)
|
||||
- GWEncoder automatically uses AAC for MP4 containers (compatibility)
|
||||
- This provides the best of both worlds
|
||||
|
||||
If exact Tdarr parity is required, change `encoding/audio.go`:
|
||||
```go
|
||||
// Change from:
|
||||
Codec: "opus",
|
||||
|
||||
// To:
|
||||
Codec: "aac",
|
||||
```

# Default Transcoding Behavior
|
||||
|
||||
## Overview
|
||||
|
||||
GWEncoder now has updated default behavior for transcoding files:
|
||||
|
||||
### ✅ Transcode by Default
|
||||
- **H.264/x264** files → Transcode to AV1
|
||||
- **HEVC/H.265** files → Transcode to AV1 (changed from skip)
|
||||
- **VP8/VP9** files → Transcode to AV1
|
||||
- **All other codecs** → Transcode to AV1
|
||||
|
||||
### ⏭️ Skip by Default
|
||||
- **AV1** files → Skipped (already in target format)
|
||||
|
||||
## Force Transcoding
|
||||
|
||||
To force transcoding of AV1 files (or any file), use the `--force` or `--force-transcode` flag:
|
||||
|
||||
```bash
|
||||
# Force transcode an AV1 file
|
||||
./gwencoder --fast --force input.av1.mkv
|
||||
|
||||
# Force transcode with full flag name
|
||||
./gwencoder --fast --force-transcode input.av1.mkv
|
||||
```
|
||||
|
||||
## Changes Made
|
||||
|
||||
### 1. Default Parameters (`encoding/av1.go`)
|
||||
- **SkipHEVC**: Changed from `true` to `false`
|
||||
- HEVC files are now transcoded by default
|
||||
- **ForceTranscode**: Remains `false` (default)
|
||||
- AV1 files are skipped unless `--force` is used
|
||||
|
||||
### 2. Skip Logic (`encoding/av1.go`)
|
||||
- Only AV1 files are skipped by default
|
||||
- HEVC files are transcoded (unless `SkipHEVC` is explicitly set to `true`)
|
||||
- All other codecs are transcoded
|
||||
|
||||
### 3. CLI Flags (`main.go`)
|
||||
- Added `--force` as a shorter alias for `--force-transcode`
|
||||
- Both flags now work: `--force` and `--force-transcode`
|
||||
|
||||
### 4. Help Text (`main.go`)
|
||||
- Added "DEFAULT BEHAVIOR" section to help output
|
||||
- Clarified that AV1 files are skipped by default
|
||||
- Updated flag description for `--force`
|
||||
|
||||
## Examples
|
||||
|
||||
### Default Behavior (No Flags)
|
||||
```bash
|
||||
# H.264 file → Will transcode to AV1
|
||||
./gwencoder --fast input.h264.mkv
|
||||
|
||||
# HEVC file → Will transcode to AV1
|
||||
./gwencoder --fast input.hevc.mkv
|
||||
|
||||
# AV1 file → Will be skipped
|
||||
./gwencoder --fast input.av1.mkv
|
||||
```
|
||||
|
||||
### Force Transcoding
|
||||
```bash
|
||||
# AV1 file → Will transcode (forced)
|
||||
./gwencoder --fast --force input.av1.mkv
|
||||
|
||||
# Any file → Will transcode (forced)
|
||||
./gwencoder --fast --force input.any.mkv
|
||||
```
|
||||
|
||||
## Rationale
|
||||
|
||||
This behavior provides:
|
||||
1. **Efficiency**: Skips files already in the target format (AV1)
|
||||
2. **Completeness**: Transcodes all other codecs to AV1 for consistency
|
||||
3. **Flexibility**: `--force` flag allows re-encoding when needed (e.g., quality adjustments)
|
||||
|
||||
## Comparison with Tdarr
|
||||
|
||||
| Behavior | Tdarr | GWEncoder |
|
||||
|----------|-------|-----------|
|
||||
| AV1 files | Skip (unless force) | Skip (unless `--force`) ✅ |
|
||||
| HEVC files | Skip (default) | **Transcode (default)** ⚠️ |
|
||||
| H.264 files | Transcode | Transcode ✅ |
|
||||
| Other codecs | Transcode | Transcode ✅ |
|
||||
|
||||
**Note**: GWEncoder's default behavior is more aggressive in transcoding HEVC files compared to Tdarr, which skips them by default.

--fast --extract-subs --remove-subs-after-extract
|
||||
```
|
||||
|
||||
**With CC extraction**:
|
||||
```bash
|
||||
--fast --use-cc-extractor --embed-extracted-cc
|
||||
```
|
||||
|
||||
## Flag Precedence
|
||||
|
||||
When multiple flags affect the same setting, the order of precedence is:
|
||||
|
||||
1. **Explicit flags** (e.g., `--av1-preset 8`) override mode defaults
|
||||
2. **Mode defaults** apply when flags are not specified
|
||||
3. **Container-based defaults** apply for codec selection
|
||||
|
||||
## Notes
|
||||
|
||||
- All flags are optional except the encoding mode (`--fast`, `--web`, etc.)
|
||||
- Flags can be combined in any order
|
||||
- Some flags require values (e.g., `--av1-preset 8`)
|
||||
- Boolean flags don't require values (e.g., `--force-transcode`)
|
||||
- Default values are mode-dependent
|
||||
|
||||
## Examples
|
||||
|
||||

Features resolution-aware CRF, improved threading, and smart efficiency filtering.
|
||||
Includes capped CRF bitrate control for optimal bandwidth management.
|
||||
**High-speed, mid-high quality defaults**: Preset 10 (M10), CRF 29, tune 0 (VQ), SCD 1, AQ 2, lookahead -1, TF on, keyint -2, fast-decode 1, 8-bit.
|
||||
Use presets 3–6 and/or lower CRF for higher quality when speed is less important.

Looking at your gwencoder code, I can see a few areas that could use some attention, dude.
|
||||
Issues I spotted:
|
||||
|
||||
The progress tracking claims exist but aren't actually implemented - You get the total duration but never use it to show actual progress during encoding. The encoding just runs silently until completion.
|
||||
Error handling for the --abr flag could leave audioBitrate empty - If someone passes --abr as the last argument without a value, you'll skip it but won't handle the missing value gracefully.
|
||||
The stats system is pretty basic - It just overwrites the stats file each time instead of actually tracking cumulative data. Your "total_files" is always "1" (as a string, not even an int).
|
||||
Conflicting codec flags aren't handled - If someone passes both --x264 and --nvhevc, the last one wins silently. Should probably error out or at least warn.
|
||||
The FFmpeg stderr capture for progress is collected but not processed - You're capturing stderr into a buffer but only dumping it on errors. FFmpeg outputs progress info to stderr that you could parse.
|
||||
Container compatibility logic is scattered - The rules about which codecs work with which containers are spread throughout the code and could be centralized.
|
||||
|
||||
implement actual progress tracking using FFmpeg's stderr output parse the time codes and show a nice progress bar with ETA
|
||||
|
||||
that stats system could actually accumulate data properly to be useful to see your total encoding time over weeks/months.

|

|

cat << 'EOF'
|
||||
|
||||
STEP 1: Add Resolution field to EncodingOptions struct
|
||||
-------------------------------------------------------
|
||||
Find the EncodingOptions struct (search for "type EncodingOptions struct")
|
||||
Add this field:
|
||||
|
||||
Resolution string // Resolution preset (480p, 720p, 1080p, original)
|
||||
|
||||
|
||||
STEP 2: Add resolution flag in parseFlags() function
|
||||
----------------------------------------------------
|
||||
Find where flags are defined (search for "flag.String" or "flag.Bool")
|
||||
Add this line with the other flag definitions:
|
||||
|
||||
resolution := flag.String("resolution", "", "Target resolution (480p, 720p, 1080p, original)")
|
||||
|
||||
Then in the EncodingOptions initialization, add:
|
||||
|
||||
Resolution: *resolution,
|
||||
|
||||
|
||||
STEP 3: Integrate into encodeFile() function
|
||||
--------------------------------------------
|
||||
Find the encodeFile() function and locate where FFmpeg command is built.
|
||||
Add this code BEFORE building the FFmpeg command:
|
||||
|
||||
// Build scale filter for resolution preset
|
||||
scaleFilter := ""
|
||||
if opts.Resolution != "" {
|
||||
filter, err := encoding.BuildScaleFilter(file, opts.Resolution)
|
||||
if err != nil {
|
||||
fmt.Printf("⚠️ Warning: Could not build scale filter: %v\n", err)
|
||||
} else if filter != "" {
|
||||
scaleFilter = filter
|
||||
targetHeight := encoding.GetResolutionPresetHeight(opts.Resolution)
|
||||
fmt.Printf("📐 Scaling video to %dp\n", targetHeight)
|
||||
}
|
||||
}
|
||||
|
||||
Then when building the FFmpeg args array, if scaleFilter is not empty,
|
||||
add it to the command arguments (typically after video codec args).
|
||||
|
||||
|
||||
STEP 4: Update printHelp() function
|
||||
-----------------------------------
|
||||
Find the printHelp() function and add in the appropriate section:
|
||||
|
||||
fmt.Println("\n📐 Resolution Options:")
|
||||
fmt.Println(" --resolution <preset> Scale video to target resolution")
|
||||
fmt.Println(" Options: 480p, 720p, 1080p, original")
|
||||
fmt.Println(" Only scales down, never upscales")
|
||||

||||
|
||||

||||
