Decoding protected AAC requires QuickTime
so this means that I can't use the fileplayer (which expects audio
files) when I use the quicktime api for decoding those protected files ?
The 10.4.7 update was just released today -- do these problems
persist on 10.4.7?
ah good news! I've just upgraded and all of the problems seem to be
gone on PowerPC. this is great!!
I'll be able to do some testing on intel machines tomorrow. I'll let
you know...
thanks,
Karim

Hi,
I'm using the file player au in my app and I've experienced some
problems with certain file formats.
When I try to play these files with any of the common audio
applications it works fine.
so I was wondering why none of these them can be opened/played
with the fileplayer (or afinfo, afplay etc.) and if there's a work
around.
(by the way..is there a list of all formats supported (or not
supported) by the fileplayer somewhere... I couldn't find it in
the docs.)
Any file format that can be read by the AudioFile API, if it
contains a data format that can be decoded (if not PCM) by
AudioConverter. Trying building afconvert (from AudioFileTools) in
the CA examples and running it without arguments -- it will list
the supported file and data formats.
trying to open/play any of these files fails:
-protected AAC audio file (from the iTunes Music Store)
-> Error: open audio file ('typ?')
Decoding protected AAC requires QuickTime -- playing a file on an
unauthorized computer can lead to a dialog prompting you to go the
iTunes store and authorize your machine as I just was reminded...
-some mpeg-1, layer-3, 192 kbps, 44,1 khz, stereo files
-> Error: open audio file ('dta?')
-m4a files on intel core duo's
-> loading works, but resetting the fileplayer is not possible,
even caused AU lab crash (I've filed a bug report about this a
while ago)
The 10.4.7 update was just released today -- do these problems
persist on 10.4.7?
