search for: speex_bits_insert_terminator

Hi everybody, I have been examining on how I can use speex completely so I have one more question. I looked at examples and source code and it goes on. speex_bits_insert_terminator is called in speex_bits_write function. Shall I call this method one more time anywhere? Because in speexenc project, firstly speex_bits_insert_terminator is called then speex_bits_write is called when we assume that nframe=1. But according to manuel, only speex_bits_write function is called. What...

David, Here's the trick ... do this just before your speex_bits_write(): speex_bits_insert_terminator(&bits); Then, when decoding, keep calling speex_decode() until it returns -1 or speex_bits_remaining(&bits) returns 0. Works for me, anyway. Tom David Barrett (dbarrett@quinthar.com) wrote: > > Hi, I'm using Speex and I want to pack multiple frames into a single > packet....

After searching the mailing list archive (I forgot to do that before posting, sorry!) I found the solutions: 1) The documentation has a mistake: The bit terminator is NOT set automatically! (I'm using the latest speex version!) It has to be set manually using speex_bits_insert_terminator(&bits); 2) speex_decoder_int() has to be called as long, as it returns -1. After that, all frames should be decoded. This should be added to the docu! Bugreport: I tried using speex_bits_remaining() instead of checking the return value of speex_decoder_int() but this leads to an endless loop!...

Yes, that's right. speex_bits_insert_terminator keeps calling speex_pack_bits forever, because bitPtr never reaches 15.

Alright noted, I changed me code so that the state is created in the constructor and destroyed in the destructor of the object. However I'm still getting the same issue although I'm sure that would have bit me sooner or later. The new code is as follows. virtual Enigma::u8* Encode(Enigma::u8* inputBuffer,size_t inputSize, size_t& outputSize) { short *in=(short*)inputBuffer;

I have non terminate loop when decode speex bits stream. These are my pseudocode for encoding and decoding -- Encode -- while(stillhaveinput) { speex_encode(enc_state, curr_spx_frame, &bits); } speex_bits_insert_terminator(&bits); speex_bits_write(&bits,(char *)(pBufferOut),MAX_LEN); -- Decode (these code loop forever) -- speex_bits_read_from(&bits, (char *) pBuf,act_length); result=speex_decode(dec_state, &bits, curr_spx_frm); while(result==0) { result=speex_decode(dec_state, &bits, curr_spx_f...
