Enhancement request : add GPU based yuv to rgba conversion

[RobertFlatt]

Video playback when the fails with missing codec when source was recorded on a GoPro:

10-08 10:08:25.493 27836 27869 I python  : [WARNING] [ffpyplayer  ] No decoder could be found for codec hevc

I suspect that wherever you got the linked ffmpeg from was built without libx265 support. Our wheels should have support for it.

[RobertFlatt]

yes, I was missing ffpyplayer_codecs. It now fails with

Which looks SDL2 related libsdl-org/SDL#7620

[RobertFlatt]

Fixed crash with

os.environ["SDL_AUDIODRIVER"] = "android"

Now it is too slow to use. Presumably:

Wow, this fixed the crash on my end too (when streaming audio). Thanks Bob, really appreciated!
