hi, i have see the source of src_bios6/links_c6xdsp, there is only osd and scd.

and the Aenc_create() function call failed:

                    aencParams.bitRate = 128 << 10;
                   aencParams.encoderType = AUDIO_CODEC_TYPE_AAC_LC;
                   aencParams.numberOfChannels = 2;
                   aencParams.sampleRate = 48 << 10;

                   encHandle = Aenc_create(&aencParams);


is my idea error? thanks

    Audio related DSP code is part of rpe package which is linked in library form in dvr rdk executables. Still source is available under ti_tools folder.

    Encoder creation failure can be due to unsupported sample rate / bitrate combination. Refer the BitRate & Sample Frequency combination table present in AAC encoder user guide (ti_tools/codecs) and use the supported bitrate - sample rate combination.
