Hi list, I'm Chris, aka koying, from the XBMC team. Bear with me, I'm not a ffmpeg guru in any way ;)
I've created a PR on github (https://github.com/FFmpeg/FFmpeg/pull/79) regarding a remaining issue in h264 AnnexB conversion where "hiccups" are still to be seen if sps/pps are already in the stream. Pretty sure github PR's are not the proper way, but out of ignorance... It's a follow-up to http://ffmpeg.org/pipermail/ffmpeg-devel/2014-March/155911.html , which solved most of the issues but not all. See https://github.com/xbmc/xbmc/pull/5042 for the XBMC discussion. My best guess is that https://github.com/FFmpeg/FFmpeg/commit/289b149cecb381522cc9ccdf382825330169c655#diff-0e332ff3db7b093bfee7dda7ed82ce19 is flawed if non-idr pics have sps/pps of their own. Then ffmpeg adds extradata to non-idr pics, too. If the stream already has sps/pps of their own, I don't think there is an added value to re-add those from extradata, so this patch just don't prepend if they're already present. A sample of the issue can be seen here: http://www.semperpax.be/owncloud/public.php?service=files&t=a28e4f3e2305ba08837c45f42c4a3662 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
