Hi, Tank you for your reply. I have tried the sample programs given the manual and done encoding and decoding a wave file. That is working fine. I have already read the manual and API reference. But this problem did not occured with the wave file encoding/decoding. While capturing the data from MIC and encoding/decoding is giving this problem. Thanks and Regards, Vijender Reddy, -----

...ze of 160 samples. Hi Randy, thanks for the reply. So, suppose I encode an audio buffer (8000 kHz, MONO, float) of 640 PCM frames. In output I have 4 speex frame of 20 byte each that I put in a RPT payload of 80 bytes: UINT CSpeexCodec::Encode( float *inBuff, const char**outBuff, UINT BufferFrames ) { speex_encoder_ctl(spx_state_, SPEEX_GET_FRAME_SIZE, &spx_frame_size_); while (BufferFrames>0) { speex_bits_reset(&spx_bits_); speex_encode(spx_state_, inBuff, &spx_bits_); nbBy...

...ext, I tried a bitcode file whose first line was "target triple = "i686-pc-linux"". llc gave me the following error: FIXME: This code needs to be updated for changes in the CodeEmitter interfaces. In particular, this should set BufferBegin/BufferEnd/CurBufferPtr, not deal with OutBuffer! This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. Any help would be appreciated. Thanks, Jon

Hi, in a VoIP application, the endpoint A send speex payload to B. B doesn't know how A acquire audio, it only know that the channel is narrowband so, how can B know the size of the output buffer to pass to the speex_decode()? Thanks, Daniele.
