While the H.264 and HEVC syntax and semantics for these coincide, the HEVC implementation of it is not completely spec-compliant with respect to its persistency: The persistence ends when the coded video sequence ends and if the new coded video sequence does not have these SEIs, then we would need to attach an AVMasteringDisplayMetadata and/or AVContentLightMetadata just to cancel the earlier values. I just don't want to enter this and this includes not extending it to H.264. Anyway, I have now rebased this patchset on top of master: https://github.com/mkver/FFmpeg/tree/h2645_sei (with no noteworthy conflicts; basically the only change is that the second to last commit now adds proper newlines to the newly created files). I intend to apply it in two days unless there are objections. - Andreas _______________________________________________ ffmpeg-devel mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
