I don't see a big problem in adding stream (i.e. link-)-level side data to avfilter. We already do this for hwcontexts (which btw need to be better integrated into format negotiation). It also seems to me that video properties like stereo3D or spherical mapping are analogous to your MXF use case and they exist in side data. -- Anton Khirnov _______________________________________________ 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".
