Hi, I've attached a patch against SVN r14645 which adds GCC visibility information to all symbols exported from libspeex.so and libspeexdsp.so. It includes a configure.ac change to test that both the compiler flags and __attribute__((visibility)) works, and if so will #define EXPORT __attribute__((visibility("default"))) and if not #define EXPORT I've attached a diff output

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

Hi, I am using the JitterBuffer. Since there is not so much documentation I think I dont use it in a correct way. All the packets are recieved (I control the sequence numbers) but the JitterBuffer often tells me he has no packet. I am using it in the following way: I am not sure if I use the ticks correctly but I think it can be set to 20(msec). It is set as a Member in my class and i

This patch will export new speex functions in the generated library, such as speex_encode_int as well as the preprocessor, echo-cancellation and jitterbuffers. The ordinals used matches the 1.1.6 release from the speex.org website, so any new library created with this def file should be binary compatible with that one. -------------- next part -------------- Index: speex.def

Thanks for your reply Jean-Marc! this was what I had before. But I decided to restructure it since the thread that plays the sound is a callback from the sound hardware, more or less an interrupt handler. For me it seems more reasonable to waste some memory for to save the decompressed Packet. While I write this I begin to think that it is possible I decompress Packets that are never used

Hi. After changing my code to construct a JitterBufferPacket and passing that to speex_jitter_put, my program works with the new jitter buffer using the wrapper functions (speex_jitter_* instead of the new jitter_buffer_*). However, a lot of warning: did you forget to call jitter_buffer_tick() by any chance? is displayed. Looking at speex_jitter_get, the logic seems to be as follows: if

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, The attached patch fixes an incistency in my earlier patch. Whereas the rest of the AGC ctls are in dB, GET_AGC_GAIN was linear. This patch fixes that. It also changes the API for _GET and _SET_AGC_LEVEL to use a int32 instead of a float, meaning we don't need to do a API change when we get a fixed point AGC.

Did you check it against the trunk in SVN? If it's not applied, and you can hook Jean-Marc up with an email address like yours, I'm sure he will get right on it. :) Tom Mihai Balea <mihai@hates.ms> wrote: > > Hi all, > > Did anything happen to this patch? > It seems to me that it fixes a valid issue, but I'm not an expert. > Anyways, I didn't see

There is a problem in speex_preprocess_ctl. Both speech_prob_start and speech_prob_continue are set to 327.67 for all input values except 0 which results in 0. This is in floating point mode. I think the included patch fixes the problem. Mikael -------------- next part -------------- Index: libspeex/preprocess.c =================================================================== ---

I use the speex version of your jitter, and in speex_jitter_get, you always call the jitter_buffer_update_delay. -----Original Message----- From: Jean-Marc Valin [mailto:jean-marc.valin@usherbrooke.ca] Sent: dimanche 18 mars 2007 13:06 To: Ouss Cc: speex-dev@xiph.org Subject: Re: [Speex-dev] Problem with the svn jitter buffer > I think that the new Jitter Buffer have a problem. > >

Since r12660, the speex_jitter_get with high latency doesn?t works, I have no sound. Before this release, the speex_jitter_get works in all conditions. speex_jitter_get return void, then I cannot know the reason of this problem.

Hi Jim, Actually, I don't see anything wrong with the internal structure having a different type than the interface, as long both types are big enough to hold the possible values (in this case 0 and 1). Though, as you pointed out, testenc needs to be fixed to use spx_int32_t instead of int. I'll change that. Jean-Marc Jim Crichton a ?crit : > st->highpass_enabled is typed

Dear speex developers and users, I'm considering adopting the speex jitter buffer for use with a different codec in a voice conferencing system and would be very grateful if those more acquainted with it could help me with some questions. The speex_jitter_buffer.c wrapper seems to maintain (buffer?) one packet-frame ("current_packet") in addition to the packets already

Hello, I think that the new Jitter Buffer have a problem. It works perfectly when I call the speex_jitter_put every 20ms (on my lan) but in other case (with big latency on Internet connexion), it doesn't works. The old version is OK in all cases. Hope it will helps. Thanks Ouss -------------- next part -------------- An HTML attachment was scrubbed... URL:

In bits.c\speex_bits_pack there is logic to reallocate the bits buffer. In that section there is a call to speex_memset_bytes which appears to wipe out all the old bytes. I found when I encoded a multi-frame message that needed less than the default 2000 bytes for bits->chars, everything worked fine. However, when I encoded a longer message that triggered the realloc code in speex_bits_pack,

another optimization you can do for packing bits together... the original one is : ------------------------------------------------------------------------------------------------------------- void speex_bits_pack(SpeexBits *bits, int data, int nbBits) { int i; unsigned int d=data; if (bits->bytePtr+((nbBits+bits->bitPtr)>>3) >= bits->buf_size) { //remain
