Doing the same with mpv 0.40 compiled with the same ffmpeg version (7.1.1) on the same video, leads to an error:

Expected Behavior
The mpv command to tonemap succesfully like ffmpeg
Actual Behavior
MPV command failed
Log File
Sample Files
No response
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 files, parameters, and conditions used in "Reproduction Steps", with the addition of
--log-file=output.txt. - [x] I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
- [x] I attached the full, untruncated log file.
- [x] I attached the backtrace in the case of a crash.
