Hello, I intend to make a speex port for freescale DSP56F800/E. I downloaded the source code, but I not realize which function are called in which order for encode after calling speex_encode (or speex_encode_int) and speex_decode (or speex_decode_int). Could anybody help me on this? Thanks in advance Alexandre Penna

Narrowed it down a bit. For me the code crashes encoding the second frame if the first encoded frame was all zeros. Can someone else reproduce this or am I on crack and should look for a bug elsewhere? // Initialize speex encoder. SpeexEncoderBits = new SpeexBits; SpeexEncoderState = speex_encoder_init(&speex_nb_mode); INT FrameSize, SamplingRate = 8000, // 8000 Hz BitRate

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

It's not an include file missing. This is a link error. You need to link with libspeex (or whatever it's called when you build it).

Hi Jean, I'm trying to compile the encode.c and or the test programs that are on the site and in libspeex respectively. however, i keep getting some undefined references to the basic speex functions(see compiler log). a query on google showed that this question was posed but no answer given. I traced them down to speex.c. however when i build my project i still get these undefined referneces.

Hi, I've been doing some development for Pocket PC 2003 applications and have happened to chance upon Speex. To date, I've been having some issues in linking libspeex.lib with my application in MS Visual Studio 2005. Upon building my program, I will always receive the error: fatal error LNK1181: cannot open input file 'd:\Recorder\libspeex.lib' Recorder A brief description

This is resolved: apt-get remove libspeex-dev cd ~/src/speex-1.2rc1/ ./configure --prefix=/usr make; make install cd ../ffmpeg ./configure --enable-libspeex make; make install worked; then I was able to decode a Speex .flv file: ~/flvs$ ffmpeg -i SpeexQ6R16Efalse.flv foo.wav FFmpeg version SVN-r17174, Copyright (c) 2000-2009 Fabrice Bellard, et al. configuration: --enable-libspeex

Hi all, i'm going to try to create an app using libspeex (Speex 1.1.10) and Visual Studio and just have a few questions. First, what's the difference between libspeex and libspeex_dynamic? Do I need to include both projects in my new workspace? Next, how do I enable fixed_point using libspeex? Am I correct in assuming that an ARM processor would be able to record speech as speex files

Hi All, i have configured speex1.2rc1 for xscale-elf (ARM architecture) ,then executed MAKE and MAKE INSTALL. so, i obtained libspeex.a in the /usr/local/lib with libogg.a compiled as well. but i when i link the library to my program (by adding LDFLAGS += -lspeex -lm ), and try to compile, i get this error: /usr/lib/gcc/xscale-elf/3.4.3/../../../../xscale-elf/bin/ld: cannot find -lspeex collect2:

Thanks for the reply, i added (LDFLAGS += -L/usr/local/lib -lspeex -lm) to Makefilebut the error is still appearing ! /tmp/ccDFH8gi.o(.text+0x179c): In function `main': : undefined reference to `BlinkC$speex_bits_init' collect2: ld returned 1 exit status make: *** [exe0] Error 1 i am trying to guess what is missed to correctly link to the lib .Do you have suggestions?

Hi, Can you please confirm/give any sample on the "tick" value to be passed to jitter_buffer_init ( int tick ) ? Is this: Tick = GetTickCount() ?

I'm aware of the problem, but I don't know how to get autoconf to handle that properly. If someone knows how to make that work with autoconf even with non-gcc compilers and with default CFLAGS, I'm interested. Jean-Marc Le jeu 01/04/2004 à 17:21, Michael T.

hello, we start to develop an open source project. This project is a VoIp application with the same features like "Teamspeak" (http://www.goteamspeak.com). Our test application run in peer to peer mode under windows 2000 and above. At the moment we are using the gsm codec (13 kbps bandwidth). Later there will be a port for *unix systems. As aforementioned the project will be released

I discovered that starting from svn commit 13186, liibspeex does not work anymore. Version 13178 and earlier works ok.

Well, for compile-time, I'd think that an #ifdef would do the trick. The only way you could do it at RUNTIME is if you perform a dlopen() on the

I have built the Speex library for Pocket PC using the FIXED_POINT flag in eVC 3. It works fine. I think the iPAQ 3600 (ARM SA 1110, I think this is a 200mhz cpu), is a bit slow for encoding in realtime. The Speex encode function takes 30+ ms to encode one 20ms sample frame in a debug build. I didn't try the release build with compiler optimization. The iPAQ 3970 (PXA250, I think this is a

Hi, I think the (small) readme has been accidentally omitted from the tarball. You can get it at http://svn.xiph.org/trunk/speex/README.blackfin Note however that all the assembly is written for gcc, not VisualDSP++.

Hi all, I'm trying to create a speex decoder library for Pocket PC platform. I then intend to use this library within my .NET Compact Framework application. But when I simply try to compile the libspeex files within my eMbedded Visual C++ environment, I receive the following error c:\documents and settings\asheeshv.grapecity\desktop\pocketpcdll\speex\bits.c(367) : fatal error C1010:
