similar to: Speex realtime encoding/decoding "Real world" usage for Windows Mobile / Symbian device

hi all, I can claim that our hotfoon service has run millions of mobile voip minutes using speex on mobile and desktops. it works! earlier you needed more powerful cpus (until the integer port), however now the cpus are much faster and the code complexity is much lower. my only regret is of not being able to write some demo apps for speex on win mob. I will surely deliver it in june to settle this

It would be very nice to know about some good success without too much cpu issues on Nokia devices, i tried pjsip.org project on S60 FP1 E65 +200mhz ARM cpu with speex but don't had much luck in using it without having 100% cpu usage :( Please let us to know about your testing E65 CPU: http://www.nokia-tuning.net/index.php?s=processor Fabio Pietrosanti Jordan Dimov wrote: > Thank

Did a quick search and saw ARM CPUs with speeds above 100 MHz. That should actually be enough for Speex, at least for narrowband. > If you are using CSD, like for a secure telephony solution >

Is speex at this stage a good codec to use for real-time voice transmission over a direct CSD connection between two phones? Does anyone have any experience with using Speex on Nokia phones? If speex is not a good solution for this task, what would you recommend? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi all, i am not criticizing the technology itself, but the fact that from the point of view of the implementator that need to make a technological choice while selecting a codec to be used for a mobile multimedia application, speex does not provide affordable informations on "supported platform". Without arranging a test bed with a lot of devices and spending a lot of money i

Hi all, supposing to have speex working at 3.95, when VAD/CNG is employed, which is the size of those "silence" samples respect to voice samples? I am wondering if it could be possible to lower even the transmission of VAD/CNG samples by specifying "outbound" in the communication channel only 1 bit instead of sending the whole VAD/CNG packet. I am doing the same for AMR

Thank you, guys. Most smartphones in production today run at ~300MHz and above. So this shouldn't be a problem. I'll try to compile speex for Symbian (I see it's been ported, but the Symbian port is somewhat out of date?) and I'll run it on a pair of Nokia N76 phones. I'll let you know how it works out. If someone has any further advice in this direction, I would deeply

Hi Everybody: I am doing the project in speex, and want to make the lib/dll in symbian platform. I checked there is one symbian project file, including bld and mmp files in speex-1.2rc1. But while I import the project and compile in Carbide. It showing so many errors: ***Invoking abld command perl.exe -S ABLD.PL \Symbian\Carbide\workspace\speex\symbian\ export make -r

A couple of things to be noted on the symbian port. 1. the spokn.mmp file is missing window.c, please add that. 2. smallft.c is not required. it has global data that prevents compilation on symbian. 3. lbr_48k_tabels.c has a global variable called dummy_epic_48k_variable on line 37. this has to be commneted out too. 4. check that all tables are declared const. i will shortly post the symbian

hi Jean-Marc, I just updated from svn and it looks like there are some errors in the speex.mmp file. the filters.c is duplicated, and the fft/kiss.c files are still missing.. /alfred Jean-Marc Valin wrote: > Applied in svn.

Hey all, I was searching the internet and came across some code in the Vorbis repository that claims to have ported Ogg Vorbis to Symbian. I downloaded the tarball and was able to compile it on my system. So I'm new to Symbian audio programming, and even newer to Vorbis. :) Is there a quick 'n dirty API I can use to just start playing an OGG file from within my Symbian app, or do I

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

Hi, I noticed that there is some kind of reference to Symbian support in LLVM-GCC, and I'm trying to find out more about it. I configured llvm- gcc-4.2-2.5 using: > ../configure --prefix=/opt/stow/llvm-gcc-2.5/ --enable-llvm=/home/wim/Documents/Sources/llvm-2.5/OBJ_ROOT/ --disable-bootstrap --disable-multilib --enable-checking --target arm-none-symbianelf --enable-languages=objc,c,c++

hi, all, I am trying to build 1.1.12 for symbian platform like this: 1, bldmake bldfiles 2, abld build wins udeb (to build for emulator) but building failed, the error message is : nmake -nologo -x - -s -f "\Install\Symbian\8.0a\S60_2nd_FP2\EPOC32\BUILD\HOME\MYOWN\NOKIA\SPEEX\SPEEX-1.1.12\SYMBIAN\SPEEX\WINS\SPEEX.WINS" LIBRARY Mdf.c

Hi every one, I know that speex suports Symbian now in the unstable release but I wounder if any one can compile a decoder for Symbian MMF? I have googled for one but ending up with only "yes, speex suports Symbina" and no binary. I would use it to finaly listen on my audiobooks but I think it would be a good demonstration aplication.
