AUDIO: DEC -> AUDIO: Rpe process call failed, status: 1

Hi,

I am using DVR-RDK3.50 for DM8168 EVM.

I am trying to decode AAC audio frames coming from RTSP client. But Adec_process() funtion returns the error "AUDIO: DEC -> AUDIO: Rpe process call failed, status: 1"

See below code,

    memcpy((void *)b129AudDecCtrl.inBuf, pBuffer, bufferSize);

    b129AudDecCtrl.decPrm.inBuf.dataBufSize = bufferSize;
    b129AudDecCtrl.decPrm.inBuf.dataBuf = b129AudDecCtrl.inBuf;
    b129AudDecCtrl.decPrm.outBuf.dataBufSize = b129AudDecCtrl.outBufSize;
    if(Adec_process(b129AudDecCtrl.decHndl, &b129AudDecCtrl.decPrm) < 0)
    {
        printf("Failed to processd encoded audio\n");
        return -1;
    }

pBuffer here in this case is a buffer received from RTSP client and bufferSize is number of bytes that pBuffer contains.

can anyone tell which situation causes this error ?

Seeking quick response.

In our project,we also use Adec_process() funtion to decode the aac data get from RTSP,I encountered similar problem,I think,there are some reason can lead to this error:

(1)the aac data you get from RTSP is not a complete frame,That is to say the decode data is erro.

(2)the buffer you used to decode(inbuffer and outbuffer) is not alloc from SR.

May have other reasons can cause this error,the above is the reason I can think of.

Hi dongmei,

I am not sure about the first reason. It may be possible.

But inBuffer and outBuffer are successfully allocated from SR.

Did you able to resolve above error ?

Thanks,

This is a pure codec process call failure. Check if you in bytes are as per min input buffer requirement. Comment out the return statement and interpret the extended error.

I encounter this error because my aac stream is audio data encoded by AAC-MAIN type(not AAC-LC),so insure your aac stream is aac-lc format firstly.

if your encode format isAAC-LC,I Isuggest you to understand AAC frame format first, then parse the aac stream you getted ,insure the aac data you want to decorde is a complete frame of AAC data
