Reproduction Steps

If performed playback on parakovsky.duckdns.org:8030/liq.ogg only displays the initial track name but not the ones that comes after.

Expected Behavior

If performed on another stream with the same container but with lossy compression method (ogg 320 kbps) metadata tags on track changes displays correctly test link parakovsky.duckdns.org:8030/lossy.ogg

Actual Behavior

After the initial track title displayed of the track playing at the moment of the stream mpv will keep displaying only one name as if it is continious even tho the track could be already changed. Was curious and talked with Icecast people who tested the stream and stuff and verified that the back frame configuration correct and trough ogginfo everything looks Gucci. So, having this ticket is the last resort for a poor operator to test the problem and to keep track of it.

Log File

Sample Files

No response

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.

I don't see the metadata update at all here, even your Icecast Dashboard doesn't have metadata for the lossless stream.

Actually, this is a ffmpeg issue. It's fixed by https://ffmpeg.org//pipermail/ffmpeg-devel/2023-April/308780.html and only specifically affects flac

edit:
v3 of the patch: https://ffmpeg.org//pipermail/ffmpeg-devel/2023-May/309603.html

YES! and to your point sometimes the library would play some sourced from youtube track or lekchur that don't have a metadata so..... it probably wouldn't display itself. and yes. i have ffmpeg 6.1 on the liquidsoap i don't think it works on ffmpeg 7 so far. wonder if my version is older than the patch and could i have been patching it independently somehow. thanks for your feedback. ps: foobar seems to display metadata correctly which probably means the patch is already there but not helping our beloved m.p.v to work it out. just saying.
