[FFmpeg-devel] [PATCH] id3v2_read_ttag not 0-terminating string

[Reimar Döffinger]

Hello,
realized while debugging http://bugzilla.mplayerhq.hu/show_bug.cgi?id=1119
that id3v2_read_ttag might 0-terminate the string, proving once more
that id3 parsers are always buggy :-P.
One solution for fixing it (though there are thousands others):
