If you use the afconvert that is installed on the system (/usr/bin/
afconvert) in Leopard, does that also fail in this way? In our
testing, etc, the afconvert in Leopard is writing M4A files with Apple
Lossless fine. So, maybe the best fix for this is to check to see if
afconvert is available on the system, and if so, use that and thus
only use the code that you have built in to your app when that is
false (which would be Tiger or previous systems)

Has anything changed in afconvert between Tiger and Leopard to cause
the following?
My 10.4 app converts AIFF/WAV files to Apple Lossless using the
afconvert tool linked into my Cocoa app. I use the command:
afconvert -f 'm4af' -d 'alac' <src> <dest>. This works perfectly in
Tiger, but my client has just switched to a 10.5 server and reports
that some (not all) files now produce 4k stubs instead of
proper .m4a files, and in testing it out I find the same.
I've recompiled everything (afconvert + my app) using the 10.5 SDK
to no effect. I get no error messages at all when it runs, but the
file that afconvert writes is essentially 'empty'.
Can anyone point me in the right direction, or suggest some
documentation to help me figure this out?
Thanks, Rob
