Reproduction Steps

I organize my music via symlinks. Only some of the symlinks (but always the same) will have trouble playing while the original file works fine.

• symlink song.ogg
• play symlink
• do that with a hundred songs, some will have

[ffmpeg/demuxer] ogg: Cannot identify new stream
[ffmpeg/demuxer] ogg: failed to create or replace stream
[lavf] error reading packet: Invalid data found when processing input.
[ffmpeg/demuxer] ogg: Cannot identify new stream
[ffmpeg/demuxer] ogg: failed to create or replace stream
[lavf] error reading packet: Invalid data found when processing input.

and fail after 50% to 70% playing.

• re-linking doesn't help.
• file only says that it is a symlink, nothing broken.
• File- and link name doesn't contain any special characters, except whitespace.

With --profile=fast and --no-config i get

[ffmpeg/demuxer] ogg: Codec not found
A: 00:00:03 / 00:00:04 (73%)
Exiting... (End of file)

Expected Behavior

Play audio file symlink normally; symlinks are considered transparent.

Actual Behavior

mpv sees (some) audio file symlinks as corrupted.

Log File

output.txt

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.

Start by reproducing the failure from the command line with the supplied sample files, comparing each symlink with its original while reviewing output.txt. The issue names no source file or test; done means the affected symlinked Ogg files play normally without the demuxer errors.
