Issue with decoding 8-bit PCM data
...bit data
ui32BitsPerSample = 8 for 8-bit data and 16 for 16-bit data
The code is as follows
sOpusDec = opus_decoder_create(ui32SamplingRate, ui32Channel, &i32error);
if (i32error != OPUS_OK)
{
return((int)i32error);
}
opus_decoder_ctl(sOpusDec, OPUS_SET_LSB_DEPTH(ui32BitsPerSample));
ui32SizeOfWrBuf =
(ui32SamplingRate*ui32Channel*FRAME_SIZE_IN_MS*ui8ScaleFactor)/1000;
opi16_out =
(int16_t*)calloc(((ui32SizeOfWrBuf/ui8ScaleFactor)+1),sizeof(int16_t));

OPUS_SET_LSB_DEPTH only affects the encoder. If you check the return
value here you should get OPUS_UNIMPLEMENTED.

I suspect the issue is dividing by ui8ScaleFactor = 1 here.
OPUS_SET_LSB_DEPTH works as a precision hint to the encoder about where
to set the noise floor, but opus_decode still returns 16 bit samples. It
always returns 16 bit samples, regardless of whether the original input...
