hi,all,
please help me!
I use pjproject-0.8.0,
when i set audio_frame_ptime = 20,aec = 1, then PaRecorderCallback and PaPlayerCallback function run exactly, but aec can't work well, do not cancell echo .
when i set audio_frame_ptime = 10,aec = 1, then aec can work well . but the PaRecorderCallback and PaPlayerCallback function do not work well, portaudio callback the PaRecorderCallback times far more callback PaPlayerCallback times, it result the aec continue reset. i find underflow in the PaPlayerCallback.
pls help me!
thanks!
test code:
static int capcounts = 0,playcounts = 0;
static int PaRecorderCallback(const void *input,
void *output,
unsigned long frameCount,
const PaStreamCallbackTimeInfo* timeInfo,
PaStreamCallbackFlags statusFlags,
void *userData )
{
.....
capcounts ++;
if (capcounts%500 == 0)
{
PJ_LOG(5,(THIS_FILE, "Recorder thread capcounts = %d,playcounts = %d",capcounts,playcounts));
}
....
return paAbort;
}
static int PaPlayerCallback( const void *input,
void *output,
unsigned long frameCount,
const PaStreamCallbackTimeInfo* timeInfo,
PaStreamCallbackFlags statusFlags,
void *userData )
{
....
playcounts ++;
if (playcounts%500 == 0)
{
PJ_LOG(5,(THIS_FILE, "Player thread capcounts = %d,playcounts = % d",capcounts,playcounts));
}
....
return paAbort;
}
