Reproduction Steps

Download http://alternativlos.cdn.as250.net/alternativlos-52.mp3 (HTTPS has expired certificate)

$ wget http://alternativlos.cdn.as250.net/alternativlos-52.mp3
$ md5sum alternativlos-52.mp3
deda55e24d486e4c9ce3972216604a87  alternativlos-52.mp3

and run mpv alternativlos-52.mp3.

Expected Behavior

1. The logo (PNG) should be shown correctly, and OSD – for example when pressing key o – should be shown.
2. No errors should be logged to the console.

Actual Behavior

Just blue background and no OSD is shown, when pressing the key o. A lot of errors are printed to the console:

Log File

20250804--mpv-libplacebo.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.

Reproduce the failure with alternativlos-52.mp3 and review the attached log, then start at libplacebo's src/gpu.c:472 and the pl_tex_upload entry shown in the backtrace. Trace the mpv GPU video-output path that reaches this validation; done means the PNG logo and OSD render without validation errors on the reported setup.
