Unfortunately I have no way of testing the D3D11 stuff in there (and I
honestly wasn't a big fan of hacking it in like that in the first
place), so unless someone contributes ffmpeg_d3d11.c and
avutil/hwcontext_d3d11.c, there isn't much about a testing setup to
confirm whatever assumptions are made in the code.
