[FFmpeg-devel] [PATCH 01/20] fftools/ffmpeg_opt: move opening input files to ffmpeg_demux.c

Tue Oct 18 15:36:42 EEST 2022
This is similar to what was done before for output files and will allow
introducing demuxer-private state in future commits
Unlike for muxing, the code is moved to existing ffmpeg_demux.c rather
than to a new file. The reason is just file size - the demuxing code is
much smaller than muxing.
