Hi,

Intel IPP supports G729B. It is incorporatedwith the G729 and G729A codecs. To encode stream with voice activity detection (from G7239B) you shouldset pInfo->params.modes.vad=1 before Init() function invoking or through Control() function. Where pInfo is the pointer to the USC_CodecInfo structure.

If you need more details about each frame processing you can analize "frametype" field of the USC_Bitstream structure afterEncode() function call.

frametype equals to 2, 3 or 4 represents frames with the active voice corresponding to the 6.4, 8.0 or 11.8 kbps bitrates.

frametype equals to -1 (Bad frame),0 (Untransmitted)or 1 (SID) represents frames with the inactive voice.
