Reproduction Steps

I am trying to use the inverse-tonemapping for SD-Material.
Therefor I am using this conf for testing:

`gpu-api=d3d11
hwdec=auto-copy
vo=gpu-next
profile=gpu-hq
video-output-levels=full

[InverseToneMap]
profile-restore=copy
target-trc=pq
target-prim=bt.709
target-peak=400
tone-mapping=spline
inverse-tone-mapping=yes
target-colorspace-hint=yes
hdr-compute-peak=no`

in the input.conf I have defined F3/F4 to activte the inverse-tonemapping and deactivte it:

a cycle audio s cycle sub I script-binding stats/display-stats-toggle x quit X quit F3 show-text "InverseToneMap"; apply-profile InverseToneMap F4 show-text "Disable InverseToneMap"; apply-profile InverseToneMap restore

This is all working fine as long as the mpv is running in window-mode. When I activate inverse tonemapping in window mode (F3) there is a clear difference in colors. When I switch to fullscreen mode and I activate inverse-tonemapping (F3) the picture in mpv gets dark. You can see some contours of the video. So it is still running but shuch dark that you can hardly decide if video is running or not. When disabling again with F4 in fullscreen picture comes back (but then without inverse-tonemapping).

I have attached a logfile. Just search in the log for "IRun command: apply-profile, flags=73, args=[name="InverseToneMap", mode="apply"]"
That was the point when I enabled Inverse-Tonemapping with F3 in fullscreen-mode and it went black

Expected Behavior

Get inverse-tonemapping working in fullscreen as well.

Actual Behavior

only working in window mode

Log File

output.txt

Sample Files

No response

I carefully read all instruction and confirm that I did the following:

• I tested with the latest mpv version to validate that the issue is not already fixed.
• I provided all required information including system and mpv version.
• I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
• I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
• I attached the full, untruncated log file.
• I attached the backtrace in the case of a crash.

I see you have some change_refresh script. Does it also happen without it?

inverse-tone-mapping=yes
target-colorspace-hint=yes

will output hdr, possibly signaling it to the display, it might be that your screen doesn't work correctly in HDR mode at certain resolution.

disabling all scripts did not make any difference. In generel the Screen is working fine (Epson LS12000) with HDR-Stuff from other sources. When I change "target-colorspace-hint" to "no" I can apply with F3 but then colors are completely washed out. So more or less doing the opposite as when it´s enabled. when enable colors are getting pushed as it should but only working in window mode as described

it´s really strange. I have recorded it via my mobile phone and uploaded here.

Example.mp4

The video starts with disable InverseTonemapping in fullscreen.
At 0:00:02 I activated InverseTonemapping in fullscreen --> screen goes dark
at 0:00:04 I disabled InverseTonemapping in Fullscreen --> screen is back
At 0:00:07 I activated InverseTonemapping in fullscreen --> screen goes dark
At 0:00:11 I pressed "alt" to open taskbar (with activated inverse tonemapping) which causes mpv to go in window mode --> screen is back with inverse tonemapping activated.

error does only exist when using

vo=gpu-next
gpu-api=d3d11

when using

gpu-api=vulkan
or
gpu-api=opengl

problem does not exist.

But then inverse-tonemapping is not working anymore.
Seems that inverse-tonemapping is only working correctly with gpu-api=d3d11

no one an idea how and where to start troubleshooting?
