inverse tone mapping doesn't work for subtitles

[rainlycoris]

Even blend-subtitles = yes, the subtitles are very dark. Is there any way to solve them?

vo = gpu-next
gpu-context = macvk
hwdec = no

scale = ewa_hanning
scale-antiring = 0.5
cscale = catmull_rom
dscale = spline36
dither-depth = 10
correct-downscaling = yes
linear-downscaling = yes
sigmoid-upscaling = yes
hdr-compute-peak = yes
hdr-peak-percentile = 99.995
hdr-contrast-recovery = 0.30
allow-delayed-peak-detect = no
deband = yes
fbo-format = rgba32f
icc-profile-auto = yes

inverse-tone-mapping = yes 
tone-mapping = bt.2446a
target-colorspace-hint = yes
target-trc = pq
target-prim = bt.2020
target-peak = 1000

blend-subtitles = yes
sub-auto = fuzzy
fullscreen = yes

hidpi-window-scale = no

The screenshots of the hdr content are not very good, but you can still notice the captions which in the top left and bottom right are too dark.

Thanks.

This will probably help https://code.videolan.org/videolan/libplacebo/-/merge_requests/630

Thank you very much! But I don't know anything about it, so what can I do, do I need to recompile mpv or other?

Wait for it to be merged or compile mpv locally with that patch applied
