It works fine on my end. I don't see any error in your log either.

If it got introduced recently, can you try bisecting it, please?

Can confirm the same issue. Log: mpvlog.txt

Maybe the problem is exclusive to intel. I don't have any intel hardware to test on, unfortunately.

Maybe @kkanungo17 can bisect it?

haasn avatar Jan 14 '23 12:01 haasn

Can also reproduce it on intel. Was not able to bisect. It seems that the issue happens IFF a polar filter is used. (And only on gpu-next with vulkan)

I'll try, but it's going to be a bit hard since it has been a while. At least for current libplacebo, mpv commit 70fa9502f3 still exhibits the same issue.

kkanungo17 avatar Jan 14 '23 17:01 kkanungo17

Yeah this is probably a graphics driver issue. Even with mpv commits going back to Feb 2022 and libplacebo v4.208 the problem persists.

It's weird that the same shaders seem to work with vo_gpu.

t-8ch avatar Jan 14 '23 18:01 t-8ch

For me this seems to work now,

t-8ch avatar Jan 18 '23 02:01 t-8ch

Yeah, works for me now as well. But so many things have updated since then I have no idea what fixed it.
