Correct, and the problem is well known. It's just that the shader based
decoding has a race condition when destroying surfaces.

If the surfaces are destroy before the decoder it works fine (like mplayer/mpv
does it), but if the surfaces are destroyed after the decoder is destroyed you
run into this crash.
