Comment (by danboid):
Thanks balling
I have got a bit closer to playing to the test file with ffmpeg using the
sdl2 demuxer but it says
"Unsupported pixel format 'nv12'"

I said previously that I didn't think my gpu supported opengl but when
using `-loglevel verbose` that is apparently what ffplay is using to play
the video although using `-f opengl -` doesn't work with ffmpeg:
