Do you have some sort of log of the failure case, and ideally a log of a similar case where it doesn't crash?
from libplacebo.
Her are 2 debug files. The Failure file is with conversion from BT2020 to sRGB and the good file is with conversion from BT709 to sRGB. Of course the goodf file has the wrong conversion In both cases I play the same UHD HDR file.
from libplacebo.
So I noticed a number of operations that are only present in the failure case:
- BT.2020 -> BT.709 pimary conversion
- PQ linearization
- PQ ootf
- Tone mapping function
- HDR peak detection compute shader
Out of all of these, the overwhelmingly most likely candidate for the crash is the peak detection shader. Try disabling it (setting the HDR peak detection period to 0).
from libplacebo.
Yes the HDR peak detection shader is the culprit. I disabled it and now it works.
As this is not realy a libplacebo issue I will close it. Maybe you can look into the HDR peak detection shader and find another way to do it. But this is realy a Intel shader problem.
Thanks for your help.

I've run into the same issue and decided to disable compute shaders on Intel for now. I'll see if I can't get it fixed this week, maybe in mesa.
