- Issue started after the following happened: After removing Pipewire to use ALSA
Reproduction Steps
- Open any live stream from twitch.tv.
- When 'Commercial break' page shows up (usually it pops up immediately when opening stream, try a few with a lot of viewers, otherwise leave it running for a bit) and this break stops playback will freeze, to unfreeze it you need to manually seek video to the end.
Expected Behavior
When using Pipewire playback continues playing, I expected same with ALSA.
Actual Behavior
Playback freezes.
Log File
Sample Files
I am unable to reproduce issue with downloaded stream so no sample file.
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.

Research direction
Start by reproducing the Twitch live-stream case with ALSA and compare it with Pipewire, using the attached out.txt log while the freeze is active. Investigate the playback behavior when the commercial break ends; done means playback continues automatically without manually seeking to the end.
