Comment (by JohnWarburton):
Using mpv linked to the FFmpeg libraries built using your patch and using
hardware decoding (I have checked for this in mpv's stdout report), the
problem is fixed on my test system.
But there is still a major problem using FFmpeg alone with hardware
decoding. Instead of a constantly green window, I am now seeing two or
three flashes per second of the correct picture, but much of the decoding
is still shown as a picture with randomly-changing blocks exhibiting
shades of green. The error message is still "hardware accelerator failed
to decode picture". So this is odd: mpv with the patched library works;
FFmpeg (opengl and SDL output, I tested both) is slightly better, but
still broken.
