## About ffmpeg-obs

# OBS Project actually patch FFmpeg to fix some issues and also add RIST support starting from 27.2.
# So I created ffmpeg-obs, a ffmpeg package that ensure that you have those.
# If you really want to use another ffmpeg package with obs-studio-tytan652:
# - Add cherry-pick from ffmpeg-obs except if you are using a git package.
# - Add obs-deps FFmpeg patches.
# - Add librist as an dependency and --enable-librist flag to the configure command except is you are using a full package.
# - Add ffmpeg-obs to the provided packages, so it acts like a drop-in replacement for ffmpeg-obs.
