IPP with RTP

Hi,
In IPP speech examples i found GSM, G.723, G.729 samples for encoding and decoding.
Can i decoding received RTP stream with GSM, G.723 or G.729 payload into Mu-Law or A-law and how can i do it ?!

p.s
I try decoding gsm file encoded by sox (GSM 06.10) but decodergsmfr.exe is crushed.

Thanks.

MPEG4 encoder decoder

Hi,

I am Hakan Demirel..
I am interested in the video processing domain of the IPP.. I have downloaded the samples for this domain. But MPEG4 samples are only for Windows.. I want to develop an MPEG4 encoder and decoder for Linux.. Are there any Linux samples for MPEG4? Or, do I have to clean out all the MFC or windows issues from the given sample codes?

IPP with GCC on Windows

Hi,

I'm evaluating IPP for use with our product and need to link it our program that is compiled with GCC on Windows, using Cygwin/Mingw. I'm having problems in the link phase with error messages like:'

undefined reference to `_ippsFFTInitAlloc_R_32f@16'

Does anyone else use GCC with IPP on Windows? If so, I'd love to know the compiler / link configuration necessary to make this work.

Thanks,
Steve

EM64T build issue

Hi All,
I have been trying to benchmark the Intel IPPs performance on a Nocona processor with Windows XP 64. I have successfully been able to use perfsys for the above.
1) Now I would like to benchmark my application. Whenever I try to build my application by using the include and lib files from the EM64T directory I keep getting link error (For e.g "IPO Error: unresolved : _ippsGetLibVersion@0"). I have tried building the code on the machine that has Windows XP 64 and also on a machine that Windows 2000, but in vain.

GSMFR encoder and decoder

I downloaded and compile speech-coding samples with evalution version of ipp 4.1.

1) I have sound file (16-bit PCM 8000 Hz).
After running encodergsmfr.exe, file *.gsm differ from a file encoded by sox. Why ?

2) Why after encoding i can't decoding same file to PCM correctly ? Only white noise.

.wav files

Hi is it possible to use the IPP fft function on wav files? If not what is the correct way to go about doing so.Ihave a wav file whose frequency content I would like to plot.

Thanks
