similar to: openh323 conflict; can speex_encode take short?

I write a sample code like speex provide , as follows: SpeeXCodec::SpeeXCodec() { rate = 8000; speex_bits_init(&enbits); speex_bits_init(&debits); enc_state = speex_encoder_init(&speex_nb_mode); dec_state = speex_decoder_init(&speex_nb_mode); // set option for encoder speex_encoder_ctl(enc_state, SPEEX_GET_FRAME_SIZE, &frame_size); speex_encoder_ctl(enc_state,

Hi, I am an user of speex codec.Can I ask some question about the speexcodec 1.2beta2 on installed to linux(fedora 6) thanks! After I downloaded the latest version of codec then I type the commands to install : configure -prefix=/home/...../test -enable-shared -enable-static make make install then I try to compile my encode.c here is the encode.c of mine: =====================================

Hi, I am new to this newsgroup. I have a problem using the Speex library. I have recorded sound data using a character buffer like char recMessg[BUFFERSIZE]. I have problem converting this to the float array for encoding. Also help me in converting the decoded information in float array back to character array. Can anybody give me function codes for this conversion. Thanks in

Hello, guys! I'm a novice at programming, learning about the speex and its applications now. Specifically, my current goal is to encode microphone input on iOS device in real-time, saving result to a file frame-by-frame. So far, I've managed to: 1) compile speex static library (it works, at least for iPhone/iPad, but not on iOS simulator; this is fine for now); 2) encode pcm data from

Hi everyone, In the 1.1.x branch, I've kept adding more stuff to libspeex: preprocessor, AEC, etc. I'm now considering moving all those to a separate library (libvoip, libspeech, whatever). Anyone on this list has good reasons I should consider for either splitting or not splitting libspeex? Cheers, Jean-Marc

I'm only doing one frame using speex_encode_int greatly simplifies my code I'm not sure why the sample I was working off of was converting the shorts to floats then calling the other encode/decode methods. Based off of your suggestions I tried the following but I get the same result. virtual Enigma::u8* Encode(Enigma::u8* inputBuffer,size_t inputSize, size_t& outputSize) {

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;

The way I do this is to compute the number of frames (by dividing the size of my input by the number of bytes per frame and then calling speex_encode_int() that many times. Something like speex_bits_reset( &bits ); for( n = 0; n < num_frames; ++n ) { speex_encode_int( enc_state, (int16_t*)input_tail,

Hi , may I ask some question about the decode files? here is my decode.c but when the program run to speex_encoder_destroy(state); It shows that segmentation fault ,I feel comfused, could you tell thanks! #define MAX_FRAME_SIZE 320 int main() { FILE *fout; char *inFile; FILE *fin; short out[MAX_FRAME_SIZE]; char cbits[200]; int nbBytes; void *state; SpeexBits bits; //int tmp; int

Hi, Guys I am starting looking the source code of Speex. Maybe a little silly, but I can not find the implementation of the function speex_encode(). Only something like below void speex_encode(void *state, float *in, SpeexBits *bits) { (*((SpeexMode**)state))->enc(state, in, bits); } Does that mean some of the detail implementation is embedded in lib without source code? I am new in

Speex 1.0.3 uses floats, but the unstable version 1.1.x uses short.

I always think short is better over float, because most of the time we don't get float form data, from, e.g microphone / wav files <p>-----Original Message----- From: owner-speex-dev@xiph.org [mailto:owner-speex-dev@xiph.org] On Behalf Of Conrad Parker Sent: Monday, April 26, 2004 12:58 AM To: speex-dev@xiph.org Subject: Re: [speex-dev] speex_encode / speex_encode_int ... already sorry

Hardware generally uses integer samples, but a number of newer software systems use float. On modern host cpus it's just as fast and you don't

Hi, i'm following encoder example in the manual.pdf of speex documentation. Here's my portion of code: int SPEEX_EncodePCM(struct _IDA_ClientSocket *IDA,char *buffer,unsigned char *PCM,int num_samples) { int ret,c,d=0,nbBytes,ttBytes=0; float PCM_F[160]; char cBits[200]; #ifndef DISABLESPEEX speex_bits_reset(&IDA->speex_bits); for(c=0;c<num_samples;c++) {
