libplacebo Tonemap not working

[GeoffreyA]

When I try to use libplacebo in VapourSynth, I get the following error repeated for each frame:

Validation failed: !params->renderable || fmt_caps & PL_FMT_CAP_RENDERABLE (../subprojects/libplacebo/src/gpu.c:250)

Critical: Failed creating GPU textures!


from vapoursynth import core

clip = core.lsmas.LWLibavSource(r"4k.mkv")

clip = clip.fmtc.bitdepth(bits=16)

clip = clip.placebo.Tonemap(src_csp=1, dst_csp=0)

clip = clip.fmtc.bitdepth(bits=8)

clip.set_output()


libplacebo works in FFmpeg. The GPU is an Arc B580, but I used to get similar errors with the Radeon iGPU. Resample() works. Am I using Tonemap() correctly, or could this be a driver problem?

Which libplacebo do you use? (from: https://github.com/Lypheo/vs-placebo ? https://github.com/sgt0/vs-placebo ? https://github.com/Mikewando/vs-placebo ? Which version?)
Using https://github.com/sgt0/vs-placebo with:

core = vs.core
# Limit frame cache to 48473MB

sys.path.insert(0, os.path.abspath(scriptPath))

# setting color range to TV (limited) range.

# color adjustment using ToneMap (Placebo)
clip = core.placebo.Tonemap(clip=clip, src_csp=1, dst_csp=0, src_min=0.0050, src_max=1000.0000, dst_min=0.2023, dst_max=203.0000, dynamic_peak_detection=1, smoothing_period=100.00, gamut_mapping=0, tone_mapping_function=0, tone_mapping_param=0.000)

# set output frame rate to 25fps (progressive)
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# output
clip.set_output()
works fine here. (using my NVIDIA GPU)

I guess that "Failed creating GPU textures" is a driver problem or incompatibility.
Maybe increasing the log_level gives further details.
You could also try the other repositories I linked to.

Thank you, Selur.

I was using https://github.com/sgt0/vs-placebo, the latest version.

Trying the other repositories, it fails with different errors. Trying your script, with some lines commented out and changing the source plug-in, same. So, I reckon the problem is in the driver.
