How to decode AMRNB NO_DATA frame with USC?

Hello, all,

Recently, I use intel ipp(8.2.3) and USC to do transcoding between amrnb and g711. I got error code: USC_UnsupportedBitRate.

Go through source code, I found this error is reported from below code. And more analysis, the error frame is AMR NO_DATA frame.

// file: uscgsmamr.c
// func: static USC_Status Decode(...);
bitrate_idx = CheckRate_GSMAMR(in->bitrate);
USC_BADARG(bitrate_idx < 0, USC_UnsupportedBitRate);

My question: How to decode AMRNB NO_DATA frame with USC?

I am a newer, and if this no data frame does not need to do decode? thanks.

Thanks and Br,

Chason

Hi,

Codec functions in IPP is out-of-date, please use the ones in Media SDK.
