Two reasons: 1. I was not sure what is the right format of that string. I saw some examples, like hvc1.2.4.L123.B0. But I didn't know what that meant. If somebody here could provide some explanation or the relevant spec, I will hold off this patch and would definitely try implementing it.
2. I heard recently in a demuxed talk that for 2K and 4K resolution Apple clients don't playout properly even when properly constructed CODEC tag is there(hvc1.2.4.L153). But they played properly without a CODEC tag. https://www.twitch.tv/videos/323919819 , Seek to 42:30 for the relevant info. For the above two reasons, I assumed it is going to be a time-consuming job. Hence, I decided to atleast restore the earlier status for HEVC, so that we don't break anything that was working properly earlier. > > - Hendrik > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-devel _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
