Mpv doesn't load the audio of a video format .PSS.

mpv Information

Hello. Mpv doesn't load the audio of a video format .PSS. A PlayStation 2 video format.
"MPEG sequence, v2, program multiplex"

The frames of the video loads correctly, but the audio doesn't.
This problem occurs in all .PSS files that I reproduced with mpv.

Thanks.

No response

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.

Start by reproducing the issue with a .PSS PlayStation 2 video using the reported latest mpv build, then inspect the linked log or output.txt. Compare the stream information for the video and audio portions; done means mpv loads and plays the audio from representative .PSS files, with a regression test or reproducible verification covering the format.
