PLUGINS HOW TO

1. Make sure you add a link to ffmpeg tools in a lib folder:

mkdir lib
cd lib
git rm -r ffmpeg
git submodule add https://github.com/Josh5/unmanic.plugin.helpers.ffmpeg ./ffmpeg

2. ffmpeg/stream_mapper.py does build the ffmpeg options in that order:

3. generic_options: before input -hide_banner -loglevel info -fflags +genpts

4. main_options: no idea what that is

5. advanced_options: default cache and experimental code banned (strict 2 = strict, goes all to way to -2 = anything possible) -strict 2 -max_muxing_queue_size 4096

-strict 2

In FFmpeg, the flag -strict 2 (which can also be written as -strict experimental) allows FFmpeg to use experimental encoders and decoders that are not yet considered fully stable or safe by the FFmpeg development team. FFmpeg enforces a strict compliance scale. By default, it will block you from using experimental codecs to prevent accidental audio/video corruption or unexpected crashes. Setting -strict 2 lowers that safety guardrail.

The -strict flag accepts numeric values or text aliases. Here is how they rank from safest to most experimental:

Value	Alias	What it does
2	very	Strictly conforms to all older, ultra-stable standards.
1	strict	Strictly conforms to standard specifications.
0	normal	Default. Allows normal, stable operations.
-1	unofficial	Allows unofficial experimental extensions.
-2	experimental	Allows experimental code (same as passing -strict 2 or -strict -2).

-max_muxing_queue_size 4096

The flag -max_muxing_queue_size 4096 allocates more memory to buffer audio and video data right before it is written into the final video file.

By default, FFmpeg uses a small queue size (often 128 packets). Increasing it to 4096 gives FFmpeg a massive safety cushion to prevent a common crash known as the "Too many packets buffered for output stream" error.

TODO

• where does gitmodules.txt come from and should I host it: comes from Unmanic official sources, can be ignored
• how do I list my repo to Community Repositories: repository index file must be registered into Unmanic's central database tracker
• registration process: https://docs.unmanic.app/docs/development/plugin_repos/creating_your_own_repo/
