[FFmpeg-devel] [PATCH v2] avformat/movenc: implicitly enable negative CTS offsets for ismv

2018-07-29 Thread Jan Ekström
ISMV lacks any sort of edit list support, as well as tfxd is effectively the PTS of the fragment for most intents and purposes. Thus, if b-frames are requested without negative CTS offsets you end up with N frames' worth of delay (tfxd PTS plus the CTS offset of the first sample). Negative CTS
