Reproduction Steps

Video file link: https://pixeldrain.com/u/jrrZBVTe

Around timestamp 21 seconds, the video freezes, but the audio plays fine.
Same with plays fine with other players, such as MPC-HC, which means the video file is fine.

Expected Behavior

The video should not freeze at around the 21-second timestamp.

Actual Behavior

Around 21 seconds into the video, it freezes, but the audio plays fine.

Log File

output.txt

Sample Files

I carefully read all instruction and confirm that I did the following:
  • I tested and confirmed that the issue exists with the latest release version or newer.
  • 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

Reproduce the linked sample in mpv on Windows and inspect output.txt around the 21-second timestamp, where buffering, EOF, and render-queue underrun are reported. Compare playback with the stated conditions and trace the relevant video playback path; done means the sample no longer freezes while audio continues.
