I have no definite knowledge nor proof, but I would have thought these are persistent, IE it's legal to update some of them, their validity depending on something else. Wondering if the tested streams are thus conformant. But I don't know the actual rule. Maybe finding an EOB/EOS NUT? Related to some particular shape of a clean random access point, that would require retransmitting VPS/SPS/PPS/APS/... ? Asking Benjamin Bross might be a better option here. > _______________________________________________ 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".
