[Flac] Decoding a continues stream

[GOO Creations]

Hi,

I've trying to decode a FLAC audio stream. I have a reader which sends 
raw byte data to my FLAC wrapper class. Only once the decode function 
below returns, the reader will send new data.
Hence I want to decode until the stream is empty, but I will add new 
data to the stream once it is empty.

*void **MyFlacCoder::**decode(char *data, int bytes)
{
         mBuffer = input;
         mBufferBytes = bytes;
FLAC__stream_decoder_process_until_end_of_stream(mDecoder);
}
*
My read callback looks as follows:
*
FLAC__StreamDecoderReadStatus flacReadDecode(const FLAC__StreamDecoder 
*decoder, FLAC__byte buffer[], size_t *bytes, void *client)
{
     MyFlacCoder *coder = (MyFlacCoder*) client;
     int size =min(*bytes, coder->mBufferBytes);
     if(size <= 0)
     {
         *bytes = 0;
         return FLAC__STREAM_DECODER_READ_STATUS_END_OF_STREAM;
     }
     memcpy(buffer, coder->mBuffer, size);
     *bytes = size;
     coder->mBuffer += size;
     coder->mBufferBytes -= size;
     return FLAC__STREAM_DECODER_READ_STATUS_CONTINUE;
}*

As far as I understand*FLAC__STREAM_DECODER_READ_STATUS_END_OF_STREAM* 
notifies FLAC to stop decoding (no more data will come). However, in my 
case I only want FLAC to "pause" and still keep the data that was not 
processed yet, until new data is available and I call 
*FLAC__stream_decoder_process_until_end_of_stream* again. So 
*FLAC__STREAM_DECODER_READ_STATUS_END_OF_STREAM* in my case actually 
means that the current stream has no more data, but I will add new data 
to the stream once it's empty. The problem is that frames might overlap. 
Hence I can clear FLAC's buffer, because there might still be half a 
frame in the buffer that couldn't be decoded yet.

Any suggestions on how I can do this?

Thank you
Christoph
