SCAudioFill buffer help

Hi, i looked at the sample scaudiocompress, but a lot of things still confuse to me.

 

The fact is a can t do it work in my implementation, i have always kAudioConverterErr_InvalidInputSize except if the output format is uncompressed.

My app gives me 65536 samples (32bitfloat, 480000, stereo interleaved)repeatedly until the end of the stream, each time i’m called, i have to compress those samples and write it to the media

 

So i prepare the audio buffer list according to the output format, the probleme comes with the maxBytesPerPacket value, if i multiply this value with my number of sample , it’s too big to allocate buffer memory.

I saw the use of a variable named PullPackets, wich is not the sample count, but what is it ? why is it 5000 ? how according it with my samples ?

 

Hope you can help

 

Thanks.
