G729 at 20ms

[e_ponk]

I read IPP G729 works in 10ms at 80 framesample, how do I convert if framesampleis160 or the encoded length is 30.

does anyone can point me with sample code?

Hi

You should to feed 160 samplessequentially two times by 80 samples at once totheencode function, so to invoke the function two times in order.30 bytes of a G729 bitstreamlikely contains three 10ms frames encoded at 8000 kbps, each of 10 bytes long. So you should to feedthree times to the decode function getting as a result three 80 samples pcm output frames.

Hi,

Also it can be two encoded frames (15+15 bytes) for 11800 kbps bitrate.
