similar to: innov_save, what is it? why does it hurt me so?

This must have been an enormous pain to track down. The manual alloc routine in the TI directory (user_misc.h) clears the allocated memory, but maybe you have changed this. >> it will just start filling data in, which it shouldn't. I see that >> innov_save is set at the beginning of a for loop at: >> for (sub=0;sub<st->nbSubframes;sub++) >> { > ...

That's an Heisenbug and the most common cause is uninitialised data. I found innov_save will write over memory

Hi Jean-Marc, Hi Jim, I have also seen some problems with the 1.1.8 release on the C55x. So far I have boiled down the issues to the following: 1) We need our own "fixed_xx.h" header file. I don't know why, and haven't had time to investigate, but there is a definite improvement when I use the attached fixed_c55x.h file which has turned all the maths into inline functions.

Hi, I'm trying a quick port of this terrific codec to uClinux, a Linux-derivate for mmu-less systems. I'm particulary interested in the alloc()'s the library does, and it's stack usage. In nb_celp.c I found two lines of code doing memory allocation : nb_celp.c: st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(float)); nb_celp.c: st =

Hi I am currently trying to port speex v1.1.6 to a microcontroller with very limited memory (<64Kbyte RAM). what I found when initialising the encoder, a chunk of 32Kb was attempted to be alloced, which failed: src/nb_celp.c: void *nb_encoder_init(const SpeexMode *m) { /* snip */ st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(spx_sig_t)); /* snip */ } same goes for the

Can anyone tell me why the size of st is defined as: st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(float)); Reference: nb_encode_init function. Specifically, I would like to know why 8000 floats are allocated? Thanks and regards, Vinay -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi everyone, As you may have guess, Speex 1.2 is slowly approaching, though there's still a lot left to do so I can't say how long it'll take. I thought this was the right time to ask if there's anything missing or that can be improved to make 1.2 better. At this point, it can't be anything major, but there are still some changes that are possible, e.g: - Improving some

Hi, I am using 1.2beta2 on a C5416 doing narrowband in the decode function I am having a problem with the execution of my program vectoring off to random interrupts that are not used. I have tracked down the error to the highpass function called in nb_decode -very close to the end of the function-context: it is called here: ln 1719 for me if (st->highpass_enabled) highpass(out,

Hi, I'm one of the people working on the Rockbox project (http://www.rockbox.org) which is an open source alternative firmware for a range Digital Audio Players. Recently we integrated support for the Speex codec using libspeex and seems to work well. If you could add Rockbox to your list of software that supports Speex, that'd be great. So that's the introduction done. Now for

Hello to everyone! During building speex library for Symbian OS I encountered some problems. All thess problems can be solved by modifying the speex sources. I don't have access to SVN repository of speex, so I will just describe the changes to be done: 1) mmp file in symbian derictory misses windows.c sources. You need to add this string into speex.mmp: SOURCES windows.c 2) Symbian OS

Hello, some misc. cleanup patches for speexdsp, nothing big I'm not sure about how to submit patches, so this is a test balloon :) ultimately, I'd like to fix the FIXED_POINT issue, see http://lists.xiph.org/pipermail/speex-dev/2013-December/008465.html currently, I think the only way to find out how speexdsp has been compiled is to resample some bytes and observe the output; which is

I am trying to implement a relatively high number of encoders (24/32) on a single DSP and would like to minimize the memory requirements. Has anyone optimized the persistent EncState memory allocation for multiple channels. The default C64x fixed point implementation allocates 5280 bytes of persistent memory per encoder. I'm willing to restrict my settings to complexity 1, quality 3. It

Hi Guys, Thanks for Unicorn, it makes my world rock. You guy have done a wonderful job and also huge thanks to the predecessors too. The default timeout on my Rails app is 30 seconds. The app works fine most of the time but there are some parts of the app which are slow and occasionally totter over the 30 sec response time and timeout. Is there a clean way for me to hook into timeouts and notify

Hi, all. I have two questions about wideband encoding. >From "testenc_wb.c"... 1) tmp=8; speex_encoder_ctl(st, SPEEX_SET_QUALITY, &tmp); tmp=3; speex_encoder_ctl(st, SPEEX_SET_HIGH_MODE, &tmp); tmp=6; speex_encoder_ctl(st, SPEEX_SET_LOW_MODE, &tmp); How to set high_mode and low_mode, if quality is set to '9'? When I set quality '9'
