Description
Summary of the bug:
True Audio format supports metadata as being ID3v1, ID3v2 or APEv2.
But ffprobe doesn't detect any id3v2 metadata on the following file: http://towerofbabel.free.fr/test/music.id3.tta while mp3tag v2.55a can see that a cover art is embedded as id3v2.3.
How to reproduce:
% ffprobe.exe music.id3.tta

the complete demuxing failure is a regression since 55121f3fa92901a1917f035df534e8caa82e4f71

detection failure without .tta extension is caused by PROBE_BUF_MAX being too small

Maybe it would be more efficient when detecting ID3v2 tag to jump over ID3v2 content before starting the actual detection procedure. As ID3v2 tag are put before actual file content, it just add useless gibberish for the detection procedure.

File is not detected as tta1 at all and decodes nothing useful.
