We have a AV_SIDE_DATA_PARAM_CHANGE_DIMENSIONS flag to signal resolution changes, so both words seem to be used interchangeably. This also makes me think that the existing AV_CODEC_CAP_PARAM_CHANGE codec cap can be used for this already, without the need for a new one. It should a matter of using AV_PKT_DATA_PARAM_CHANGE packet side data afterwards in some form. _______________________________________________ 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".
