README
# dynamic-crop.lua
Script to "cropping" dynamically, hard-coded black bars detected with lavfi-cropdetect filter for Ultra Wide Screen or any screen (Smartphone/Tablet).
## Status
It's now really stable, but can probably be improved to handle more case.
## Usage
Save `dynamic-crop.lua` in `~/.config/.mpv/scripts/` (Linux/macOS) or `%AppData%\mpv\scripts\` (Windows).
Or edit your `mpv.conf` file to add `script=`, use absolute path and don't add it if you already put it in directory `scripts`:
```
## Example
# Linux/macOS:
script=/home///dynamic-crop.lua
# Windows:
script=C:\Users\\\dynamic-crop.lua
# Android mpv-android:
script=/storage/emulated/0//dynamic-crop.lua
```
## Features
- 4 modes available: 0 disable, 1 on-demand, 2 one-shot, 3 dynamic-manual, 4 dynamic-auto.
- Support hardware decoding with *-copy variant only (read_ahead_mode=1/2 required ffmpeg patch to avoid color issue)
- Correction with trusted metadata for fast change in dark/ambiguous scene.
- Support asymmetric offset (Re-center video).
- Auto adjust black threshold (cropdetect=limit).
- Ability to prevent aspect ratio change during a certain time.
- Allows the segmentation of normally continuous data required to approve a new metadata.
- Handle seeking/loading and any change of speed handled by MPV.
- Read ahead cropdetect filter metadata, useful for videos with multiple aspect ratio changes (require ffmpeg master/6+).
## Shortcut
SHIFT+C do:
Cycle between ENABLE / DISABLE_WITH_CROP / DISABLE
## To-Do
- Improve documentation.
- Improve read_ahead.
## Troubleshooting
To collect the log, add to mpv.conf, `log-file=`
If the script doesn't work, make sure mpv is build with the libavfilter `crop` and `cropdetect` by starting mpv with `./mpv --vf=help` or by adding at the #1 line in mpv.conf `vf=help` and check the log for `Available libavfilter filters:`.
Make sure mpv option `hwdec=` is `no`(default) or any `*-copy` ([doc](https://mpv.io/manual/stable/#options-hwdec)), otherwise the script will fail.
Performance issue with mpv client or specific gpu-api (solved with [patch](https://github.com/FFmpeg/FFmpeg/commit/69c060bea21d3b4ce63b5fff40d37e98c70ab88f)):
- mpv.conf: Try different value for `gpu-api=` ([doc](https://mpv.io/manual/master/#options-gpu-api)).
- Script settings: Increase option `limit_timer` to slow down limit change, main source of performance issue depending on gpu-api used.
- JellyfinMediaPlayer settings: Try with `UseOpenGL`.
