I receives G.722.1_C rtp packets(174byte 20ms),from which extract raw data(120byte 20ms ) and save as a file, then I decode the file to PCM format (the decoder I download from ITU websit,by the ITU-R Rec.G.722.1), but it just silence and bursts of noise(most byte of the PCM file is "0X00" ). I change bytes order and bits order ,nothing work. so what's the right order of bytes and bits in a frame?
I download and install IPP 2018 update 2, but I can't find the sample code of G.722.1_C .
Thanks for help
This functionality was removed to IPP legacy domain ( https://software.intel.com/en-us/articles/the-alternatives-for-intel-ipp-legacy-domains-and-functions ) and has no longer supported into latest versions of IPP.
Thank for you help Gennady F. I have download the ipp90legacy_win_9.0.0.009.zip ,but still not find the sample code of G.722.1_C,
the raw data arrange like this: frame1 frame2 frame3 ......
each frame arrange 120 Octeds like this: byte1,byte2,......byte120.
than I change order in diffrent ways :
all above not work
searching the forum , a post is similar to my situation. but it seems that problem not yet settled,how can I contact to the post author?
