warning: ‘tone_mapping_param’ is deprecated

Important Information

- mpv version: 0.38
- Platform version: Debian Testing/Sid
- Meson version: 1.5.1

Reproduction Steps

When building Debian's 0.38 version + the patch set from https://github.com/mpv-player/mpv/pull/14690 I noticed the following:

It isn't related to that PR though as I found the same issue in the log of the official Debian buildd: https://buildd.debian.org/status/fetch.php?pkg=mpv&arch=amd64&ver=0.38.0-1%2Bb1&stamp=1722255337&raw=0

I did find https://github.com/mpv-player/mpv/pull/12195 which also seems related to libplacebo deprecations, but possibly an earlier one?

BTW: I lied below about testing it with the latest version as PR 12195 is the most recent code change and that was part of 0.37 already.
Furthermore, the above warning is present in your own build logs too: https://github.com/mpv-player/mpv/actions/runs/10445387357/job/28921260649

Expected Behavior

Build without warnings

Actual Behavior

Build with warnings

Log File

mpv_0.38.0-3_amd64.build.zip

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

[X] I tested with the latest mpv version to validate that the issue is not already fixed.
[X] I provided all required information including system and mpv version.
[X] I produced the log file with the exact same set of parameters, and conditions used in "Reproduction Steps".
[X] I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
[X] I attached the full, untruncated log file.
