Log file
Are those logs supposed to be when you run mpv --no-config?
[ 0.055][v][cplayer] Setting option 'hwdec' = 'dxva2-copy' (flags = 4)
Are those logs supposed to be when you run
mpv --no-config?
Oh sorry, I fixed the logs.
I am having what I think is the same problem, on a old laptop with GMA 4500 graphics running Win 7 64-bit.
The autoselected hwdec method in working versions is dxva2-copy. In newer mpv versions, if I specify --hwdec=auto (or press Ctrl+h), mpv silently crashes, but if I specify --hwdec=dxva2-copy it still works.
The last SourceForge build that doesn't crash is 0.34.0-468-gba81e4ed88. The first that does crash is 0.34.0-483-g56e24d535e.
Looking at the commit history between those versions I see a series of commits by @philipl related to hardware decoding: e50db4292795de511531e764d7e609c1a37a204f, 5629ed81eed90f95a04bb3d8ff64f135bd186651, 989d873d6ec57171a55f432d6f87a9e5a61a706c, 7b84e6fa8988f31e297cbc3adcd8a81e18e63bc8, f221666ade9a60195a37d809973fbc18391306ed. I would guess that one of those is the culprit.
The -v log of the crashing version ends abruptly after [vo/gpu] Loading hwdec driver 'd3d11va'. The next line in the working version says [vd] Could not create device. and it goes on to try other drivers.
As it seems like I cannot reproduce it on my Win10 system, would be interesting to see the gdb backtrace of these if there could be debug symbols available. For example with https://megumin.fushizen.eu/builds/gdb-8.0.1.7z .
See https://github.com/mpv-player/mpv/issues/9562#issuecomment-986292169 for an example of how to call gdb (you might have to utilize mpv.exe specifically as mpv.com is just a wrapper which outputs the logs).
