The goal is to use this in conjunction with the previous patches in the set to deal with live broadcast streams coming off a tuner. The first patch sets the CORRUPT flag when the TEI bit is set in a TS packet (indicating that the tuner detected uncorrectable errors), the second clears the PTS and DTS in response to that flag (since a bit flip that causes a too-high timestamp can throw off the whole stream, since ffmpeg.c enforces monotonicity), and the third re-generates DTSs by interpolating from the previous packet's receipt time. > > Also, the timestamp would need to be filtered for scheduling > fluctuations. In my target use-case, being slightly off due to scheduling fluctuations isn't particularly problematic, since this is expected to only occur in the case of corruption anyway, so the whole thing is best-effort. > > Regards, > > -- > Nicolas George > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-devel _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
