Recording Audio With openAl and aac

[mahd96]

i tried to capture audio frames with openAll and decode them via aac .
it works fine in Mac-Linux but not in windows!(they are faster by 30%!!!)

is there any flag that i forget to set?

these are my aac configuratiuon

if (aacEncOpen(&aacHandle, 0,this->channelCount) != AACENC_OK) {
    fprintf(stderr, "Unable to open encoder\n");
    return false;
}
if (aacEncoder_SetParam(aacHandle, AACENC_AOT, 2) != AACENC_OK) {
    fprintf(stderr, "Unable to set the AOT\n");
    return false;
}
if (aacEncoder_SetParam(aacHandle, AACENC_SAMPLERATE,this->sampleRate) != AACENC_OK) {
    fprintf(stderr, "Unable to set the Sample Rate\n");
    return false;
}
if (aacEncoder_SetParam(aacHandle, AACENC_CHANNELMODE, channelMode) != AACENC_OK) {
    fprintf(stderr, "Unable to set the channel mode\n");
    return false;
}
if (aacEncoder_SetParam(aacHandle, AACENC_CHANNELORDER, 1) != AACENC_OK) {
    fprintf(stderr, "Unable to set the wav channel order\n");
    return false;
}
if (aacEncoder_SetParam(aacHandle, AACENC_BITRATE, this->bitRate) != AACENC_OK) {
    fprintf(stderr, "Unable to set the bitrate\n");
    return false;
}
if (aacEncoder_SetParam(aacHandle, AACENC_TRANSMUX, 2) != AACENC_OK) {
    fprintf(stderr, "Unable to set the ADTS transmux\n");
    return false;
}
if (aacEncoder_SetParam(aacHandle, AACENC_AFTERBURNER, 1) != AACENC_OK) {
    fprintf(stderr, "Unable to set the afterburner mode\n");
    return false;
}
if (aacEncEncode(aacHandle, NULL, NULL, NULL, NULL) != AACENC_OK) {
    fprintf(stderr, "Unable to initialize the encoder\n");
    return false;
}
aacInfo= { 0 };
if (aacEncInfo(aacHandle, &aacInfo) != AACENC_OK) {
    fprintf(stderr, "Unable to get the encoder info\n");
    return false;
}

Hi,

You're here on a Qt forum. That's a question better asked to the OpenAL folks.

[mahd96]

it's a combination of openAl and AAC that compilled and run correctly on Mac/Linux with Qt but not in windows.
i thought it might be a platform-dependency problem that Qt folks better know it!!

and i am not sure the problem is with openal! it might be aac

What library are you using for the encoding ? And again, that's a question better asked to the author of the library.
