...How difficult is it to convert speex_encoder_init and speex_decoder_init to use preallocated memory buffers (presumably passed by the initilisatio functions themselves)? - farhan - farhan -----Original Message----- From: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] On Behalf Of Gervase Markham Sent: Wednesday, June 28, 2006 2:55 AM To: Jean-Marc Valin Cc: speex Subject: Re: [Speex-dev] Library split (poll) Jean-Marc Valin wrote: > 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 &gt...

Hi, I want to take a .wav and generate a bytestream that I can feed direct to speex_decode(). The speexenc program appears to produce it wrapped up in an ogg stream, and it doesn't have any sort of "raw" mode. I've tried hacking on it to remove the ogg parts, but I must have got it wrong, as my decode dies after decoding 160 bytes (which I believe is one frame) with an

I would guess that the sampleenc and sampledec programs (I think they're in the doc dir) would be closer to what you want.

It would be great to get some idea of what chips and DSPs people have tried to compile Speex for, and what success they've had. So, if you've tried Speex on a chip, could you take a second to fill in the following and post it to the list? Chip Name: Speex Version: Floating or Fixed: Encode, Decode, Both or Simultaneous: MIPS (if known): Other comments: Many thanks, Gerv

...ions themselves)? All you need to do is override some of the functions in misc.c. You should need to touch anything else.

Will it definitely work, definitely not work, or might it work and no-one has any idea? :-) More specifically, I'm trying to decode Speex data encoded using sampleenc. So, it's definitely been encoded

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 can't get the versions of sampleenc and sampledec in the manual to work back-to-back. I've tried using speex 1.0.4 and 1.1.6. What am I doing wrong?
