How are you allocating the buffer? I suspect that the problem is in
the way the ABL you are using is not-matching the client format (the
format you ask the ExtAF to give you data in). (It is a little tricky
to get right sometimes).
In the /Developer/Examples/CoreAudio/PublicUtility directory there is
an AUOutputBL class that might help you with this. There is also in
the SimpleSDK directory a version of the ConvertFile code that uses
ExtAF, so you could also perhaps start there and see if changing that
reproduces your problem...
But the short answer to your question is that there is no such
requirement on the client side

Hi,
When I use ExtAudioFileRead api to read data from an mp3 file, my
application crashes after reading some data from the file. The
crash happen in the ExtAudioFileRead api. I debugged the code and
found that, when I change my buffer size >= (1024 * 5) then, my
code is running fine. But when I change the buffer size < (1024 *5)
then ExtAudioFileRead starts crashing again.
So, my question are,
- Is there a way to find out the minimum buffer size require by
ExtAudioFileRead api?
- Has anybody else faced this problem? If yes, then, what solution
you used to solve this problem?
Thanks,
Pulkit
