Comment (by tmm1):
Thanks. I forgot to specify that ffmpeg-devel is the preferred place for
patches, so they can be more widely reviewed.
As far as macOS compatibility, you can refer to how I added compatibility
checks for kCMVideoCodecType_HEVC here:
https://github.com/FFmpeg/FFmpeg/commit/3d4f8b9184a4693c577e0b73496e6cc1989c6bbf

If you feel so inclined, take a stab at adding compatibility using the
approach above and send the new patch to the ffmpeg-devel list. If not, I
will plan to pick this up in a few weeks and do the same. Thanks for your
contribution!
