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. --- fftools/ffmpeg.h | 4 + fftools/ffmpeg_demux.c | 608 +++++++++++++++++++++++++++++++++++++++++ fftools/ffmpeg_opt.c | 606 +--------------------------------------- 3 files changed, 614 insertions(+), 604 deletions(-) diff --git a/fftools/ffmpeg.h b/fftools/ffmpeg.h index 91c5cfa3ab..085a775a43 100644 --- a/fftools/ffmpeg.h +++ b/fftools/ffmpeg.h @@ -678,6 +678,8 @@ extern int input_stream_potentially_available;
