Reproduction Steps

On a system without pipewire (it may apply to pulseaudio as well), use mpv to play a file and notice the warnings seen below (they are colored in yellow and red respectively).

I used the --no-config option (which I did not know until a few minutes ago) and the warnings showed up the moment the video started playing. When using my config, the warnings show up when I press "i" (statistics overlay) and only once, no matter how many times I may press it during the playback.

Last but not least, in case it is not mpv's fault but something else, e.g. ffmpeg, I want to add that I am getting the same lines on the terminal when using kodi (21), but they appear there even when the app just launches and does nothing at all. Mpv is built with the libs of ffmpeg 7.0.1, but kodi is built with the libs of ffmpeg 6.1.1.

$ mpv --no-config klama.mp4

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 did not think the issue would date back to mpv 0.35. On my end, it happened with the upgrade to 0.38, I did not have it before.

---edit
I do not know if it is visible in the debug log, but I do have ao=alsa in my config since ever.

Probably mpv was compiled without pipewire support before.

EDIT:

I do not know if it is visible in the debug log, but I do have ao=alsa in my config since ever.

In the log you provided there is

[   0.000][v][cplayer] Setting option 'audio' = 'no' (flags = 12)

so no audio is loaded/used.

But... I do hear audio even with the --no-config option! Here is the proof that I do have alsa as my audio device in my mpv.conf

$ head -5 .config/mpv/mpv.conf 
vo=gpu,xv
#vo=xv
hwdec=vaapi
ao=alsa

Is there a command line parameter that can silence these errors only?

I am also interested in a parameter that will silence errors which come from ffmpeg, like this one
