I think it would be better, but not sure if others agree. A well defined way for decoders/encoders to inform the generic code what to expect is imo nicer than it assuming that a given value in a frame means that it was not touched, even if said value is the default. Perhaps it could be simplified into a single codec cap to sell all pkt_* fields and other props (like size and duration), rather than one cap per field. And since it's all internal, it can be removed as easily and quickly as it was added. > > Thanks > > [...] > > > ___ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe". > ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
