Important Information

Provide following Information:

• mpv version: mpv 0.34.1-dirty Copyright © 2000-2021 mpv/MPlayer/mplayer2 projects

• If known which version of mpv introduced the problem: don't know
• Window Manager and version: kwin 5.25.2

Reproduction steps

Open the sample TTA file with ID3v2 suffix using mpv. It is recommended to do this from the command line.

Expected behavior

mpv normally open the TTA audio file with ID3v2 tag and APEv2 tag.

Actual behavior

mpv can open the TTA file with APEv2 tag (or without tag) correctly, but it will consider the TTA file with ID3v2 tag to be an mp3 file.

Log file

Make a log file made with -v -v or --log-file=output.txt, paste it to https://0x0.st/ or attach it to the github issue, and replace this text with a link to it.

Open the TTA file with APEv2 tag: http://0x0.st/o11j.log Open the TTA file with ID3v2 tag: http://0x0.st/o11e.log Open the TTA file without any tag: http://0x0.st/o112.log

Sample files

TTA file with APEv2 tag: http://0x0.st/o11M.tta TTA file with ID3v2 tag: http://0x0.st/o11u.tta TTA file without any tag: http://0x0.st/o11S.tta

It looks like it's interpreting the TTA file as an mp3 file (which it isn't) because it's accepting the probescore of 48 from libavformat. Setting --demuxer-lavf-probescore=50 in the meantime can work around this. Unfortunately mp3 and ID3v2 is sort of a garbage format so I don't see an easy solution.

Thanks, it's work, and greatly alleviate this problem.

This is a bug in Firefox, stop using it. It renames http://0x0.st/o11M.tta file to .mp3, which is the bug.
