Sample Files

sample.zip

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 issue with mpv clip_pixabay_21156.ogg and the attached sample.zip, then compare the playback log with a longer audio file. No source file or test is named in the issue; done means the provided very short audio sample plays audibly without regressing normal audio playback.
