Help with CAmrToPcmDecoder

// PCM to AMR encoding example
// Use at own risk etc
// This API isn't well documented - I might have made a mistake in typing the below,
// made a mistake in working out what the parameters should have been or be barking
// up the wrong tree entirely.  If your house falls down because of using this code
// don't blame me!  However, I have had similar code working - so I think you should
// be okay ;)

// Need to link with amrdll.lib BTW
#include <amrcodec.h>

// PCM data (has to be 8000Hz, 16 Bit, mono)
byte *inputBuffer=blah;
// Length of data in input buffer
int inputBufferSize;

// Output buffer (AMR encoded)
byte *dest=User::Alloc(blah);
// Length of data written to output buffer
int outputBufferSize;
// Encoding parameters ...
TAmrEncParams encodeParams;
// Use defaults otherwise set the values below
// encodeParams.iMode=
// encodeParams.iDTX=

// Construct the encoder
CPcmToAmrEncoder *encoder=CPcmToAmrEncoder::NewL(encodeParams);

// Reset it (just in case we need to) - it not using default TAmrEncParams then
Reset(encodeParams)
encoder->Reset();

int inputUsed;
int outputUsed;
int inputOffset=0;
int outputOffset=0;
while(inputBufferSize>0) {
       inputUsed=inputBufferSize;
       outputUsed=outputBufferSize;
       encoder->Encoder(inputBuffer+inputOffset,inputUsed,outputBuffer+outputOf
fset,outputUsed);
       inputOffset+=inputUsed;
       outputOffset+=outputUsed;
       inputBufferSize-=inputUsed;
       outputBufferSize-=outputUsed;
}



And the header for the file I was talking about before - it should be #!AMR\n (any unix hackers out there will now go "hey - cool". For non unix people out there - these menas that if your AMR playing program is in your path and called AMR then you can execute a AMR file and it will be automatically loaded into your player and played). The header for wide band AMR is #!AMR-WB\n
