There's no videotoolbox support nor h265 encoding usable in myth.

Don't see the point of displaying those

[Craig Treleaven <ctreleaven@…>]

The ffmpeg resync from last November mentioned both VideoToolBox and HEVC:

​http://www.gossamer-threads.com/lists/mythtv/commits/591944

So, are you saying that we need additional MythTV code to make use of features that are in the version of ffmpeg being used? I thought we got most new ffmpeg features 'for free' in a resync. If that is not the case, I think the commit message ought to separate what Myth actually supports.

[Karl Egly]

I understood it as making x265 availability in mythffmpeg, e.g. for usage in nuvexport, visible.

I didn't think about videotoolbox. Maybe its good to know for mythffplay? If you prefer it removed I can remove it.

[JYA]

VideoToolbox was added to FFmpeg hwaccel API, it's not directly accessible to myth; we need to add support for hwaccel. Right now we use our own VDA playback. We don't use ffmpeg
