Hi everyone,
We recently installed the latest developer preview on one of the machines at work to test our application on 10.5 before it officially ships. Everything works as expected, except one part of the audio converter that converts compressed data. We're using AudioConverterFillComplexBuffer and it's working flawlessly under
10.3 and 10.4, but on 10.5 each call to this function yields the error code "561015652". Does anyone have any suggestions what we might be doing wrong?
561015652 == '!pkd'
AudioConverter.h
kAudioConverterErr_RequiresPacketDescriptionsError
= '!pkd',
You are passing a NULL AudioStreamPacketDescriptions pointer for a format whose AudioStreamBasicDescription has an mBytesPerPacket of zero.
Aha, didn't see that one. It has been working without flaws on 10.3 and 10.4, but 10.5 didn't let me convert anything unless I allocated an AudioStreamPacketDescription and filled it with the offset and current length, and then told the AudioConverterComplexInputDataProc's outDataPacketDescription about this. Thanks for the fast reply, now we're up and running again!
Regards / Mattias
What formats are you converting?
It's data in the mp3 format that's being decompressed. Should things behave differently in such a case?
