• ffmpeg bluray protocol documentation

You can access a Blu-ray directly using ffmpeg as long as you have the playlist number (which bluray_info can supply). Note that playlist must be the first option passed.

An example to simply remux a title:

ffmpeg -playlist 800 -i bluray:/dev/sr0 -codec copy bluray_playlist.mkv

Note that chapter support is broken in ffmpeg-7.1.1. No matter what argument you pass to chapter, it will always reset to the first one.
