[FFmpeg-devel] [PATCH] WebVTT demuxer - save cue id and settings as side data

[Matthew Heaney]

OK, thanks for the tips.  I determined that there was indeed a small
problem: the webvtt demuxer must specify the AVFMT_FLAG_KEEP_SIDE_DATA flag
in order to prevent the side data from being merged into the packet data.
 This error didn't show up when copying a vtt input file to a webm output
file text track, but it did manifest when converting a vtt to an ass.
