Hi,
my question has already been discussed earlier. cf. here:
http://lists.apple.com/archives/coreaudio-api/2007/Feb/msg00057.html
The problem is that AudioFileOpenWithCallbacks() fails with a 'typ?' error
on mp3s that do not have an ID3 tag. As soon as I append an ID3v1 tag
to the file, it is successfully opened by AFOWC().
Now my question: Will this be fixed in Leopard? Otherwise I could implement
a workaround by calling AFOWC() twice: If the first try fails and I see from
the ReadProc that the codec is seeking to 128 before EOF (the location of
a ID3v1 tag), I could simply set a flag, call AFOWC() a second time and have
AudioFile_GetSizeProc() return 128 bytes more, and have the ReadProc() return
a dummy ID3v1 tag from a static memory buffer. Then AFOWC() would be able
to load and play mp3s without a tag, too. But this is of course a little bit hacky,
so I'd like to know whether or not this issue will be fixed in Leopard, or if there's
something else I could do to make AFOWC() play 'tagless' mp3 files.
Tks
Andreas
