Hi all, We're trying to make ffmpeg output a format tag of 'hvc1' for HEVC, since it seems that only hvc1 works in iOS 11 beta. We saw that '-tag:v hvc1' does the trick, but it only works in 'mov' format, and not in 'mp4' format (we're using mp4 format for all our videos) The reason is that ff_codec_movvideo_tags contains hvc1 while ff_mp4_obj_type does not. The question is - is this intentional? Would it make sense to submit a patch to add hvc1 to mp4?
Also, something that I don't understand - ff_codec_movvideo_tags has 4cc values for 'tag' while ff_mp4_obj_type has small integers values, so unless I'm missing something, any attempt to force a tag in mp4 format will fail. Can anyone explain why is that? Thank you! Eran _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
