Great to see that HEVC support is finally here and that the newer devices have hardware decoding support.
I've been able to play videos from x265.com but creating HEVC from ffmpeg do not play. I'm using ffmpeg version 3.3.1 with libx265 on macOS 10.12.5. I've also treid with an older version on a CentOS server.
I've tried transcoding an H.264 video with all of the preset options. They play fine on VLC but not on an iPhone 7 Plus (nor 2016 MBP) running Beta 1.
Anyone have any luck figuring out the correct options to get the playback to work?
Ugh ffmpeg tags it as hev1 and it is not supported. I cannot find how to get ffmpeg to tag the as hvc1 but I can confirm this method of extracting the track with MP4Box works.
