# Implementation Plan - Misc Fixes "Megamix"

## Goal
Integrate functionality from `Migz1Remux`, `MigzImageRemoval`, and `lmg1_Reorder_Streams` into `Tdarr_Plugin_misc_fixes.js`.

## Proposed Changes

### 1. New Inputs
| Name | Type | Default | Description |
|------|------|---------|-------------|
| `target_container` | String | `mkv` | Output container (mkv/mp4) |
| `force_conform` | Boolean | `true` | Drop incompatible streams (e.g. mov_text in MKV) |
| `remove_image_streams` | Boolean | `true` | Remove MJPEG/PNG/GIF video streams |
| `ensure_video_first` | Boolean | `true` | Reorder streams: Video → Audio → Subtitles |
| `fix_ts_timestamps` | Boolean | `true` | (Existing) Fix TS timestamp issues |

### 2. Logic Flow

1.  **Load Inputs** & Defaults.
2.  **Determine Action Needed**:
    *   Compare `file.container` vs `inputs.target_container`.
    *   Check `fix_ts_timestamps` (TS/AVI/MPG).
3.  **Stream Analysis Loop**:
    *   **Image Removal**: IF `remove_image_streams`:
        *   Check `codec_name` (mjpeg, png, gif).
        *   Add `-map -0:idx` to drop list.
    *   **Conform**: IF `force_conform`:
        *   **MKV**: Drop `mov_text`, `eia_608`, `timed_id3`, `data` streams.
        *   **MP4**: Drop `hdmv_pgs_subtitle`, `eia_608`, `subrip` (srt?), `timed_id3`.
        *   *Note: Migz drops srt (subrip) for MP4? FFmpeg supports tx3g, maybe not srt in mp4 in older versions? I'll stick to Migz logic but allow srt if modern.* -> *Migz explicitly drops 'subrip' for MP4. I will follow Migz logic for safety but might note it.*
4.  **Construct Command**:
    *   **Pre-input args**:
        *   If TS/AVI/MPG: `-fflags +genpts`.
        *   If TS & `fix_ts_timestamps`: `-fflags +genpts+igndts -avoid_negative_ts make_zero`.
    *   **Mapping**:
        *   If `ensure_video_first`: `-map 0:v? -map 0:a? -map 0:s? -map 0:d? -map 0:t?`
        *   Else: `-map 0`
    *   **Drops**: Append `-map -0:idx` for all dropped streams.
    *   **Container**: Set output container to `target_container`.

### 3. Execution
*   Execute if:
    *   Container mismatch.
    *   Dropping streams (extraArguments > 0).
    *   Fixing timestamps (TS/AVI).
    *   Reordering needed? (Maybe always run if "Video First" is on and we want to enforce it).

## Verification Plan
*   Check TS files (ensure flags still apply).
*   Check MKV targets (ensure mov_text dropped).
*   Check MP4 targets (ensure pgs dropped).
*   Check image removal.
