[1126/140740.373:ERROR:dxva_video_decode_accelerator_win.cc(1320)] DXVAVDA
fatal error: Could not load msmpeg2vdec.dll: Module not found. (0x7E)

Maybe this has something to do with it? Disabling hardware acceleration doesn't
help in my case, but maybe it still has something to do with it? I say this
because when it was working okay, when the output belches out the vulkan info
is when it would come up and start working normally. Now at that exact point I
get the error message above. Just a desperate wild stab.
