Hi Edward,

The problem here is that , sample_rate is 24KHz for the audio buffer, and
qtdemux is also setting sample_rate as 24KHz, but later on in configure_stream
function it is overriding this to 48KHz, and my decoder is not able to play
this at 48Khz.
If the sample rate stays at 24KHz the playback is fine.

Moreover if i read sample_rate from the audio buffer it is 24KHz
eg:-

            samplingFreqIdx = ( GST_READ_UINT8 (data) & 0x03 ) << 1;
            samplingFreqIdx |= ( GST_READ_UINT8( (data) + 1 ) & 0x80 ) >> 7;

but if i read the sample_rate from the caps given by qtdemux it is 48Khz

eg:-   gst_structure_get_int( Struct, "rate", (gint *)&sampleRate )
