[Live-devel] Live streaming stops after half an hour

[Priya Raghavendra]

Hi,

On further testing I noticed that the stream works for 35 minutes, stops for 35 minutes and again recovers after 35 minutes. And this happens continuously.
What could be the problem?
Could there be some overflow of some timing parameters?
Please help me debug this issue.

Regards,
Priya

Subject: Live streaming stops after half an hour

Hi,

We have been facing this problem of live streaming stopping exactly after half an hour.
The same code works on Linux OS but windows this issue is there. The readData function does not get called,
And it does not get into the loop isCurrentlyAwaitingData.
So incomingDataHandler1 itself is not getting called.
Under what conditions will live stop calling incomingDataHandler1 ?

void LiveInputSource:: incomingDataHandler1()
{
    int ret;
    if (!isCurrentlyAwaitingData())
    {
          printf("isCurrentlyAwaitingData\n");
          return ;
    }

    ret = readData();
    if (ret < 0 )
    {
        handleClosure (this);
       printf("handleClosure (this)\n");
    }
    else if (ret == 0 )
    {
        int uSecsToDelay = 50000 ;
        nextTask() = envir().taskScheduler().scheduleDelayedTask (uSecsToDelay, (TaskFunc*)incomingDataHandler, this);
    }
    else {
        nextTask() = envir().taskScheduler().scheduleDelayedTask (0, (TaskFunc*)afterGetting, this);
    }
}

int LiveInputVideoSource:: readData()
{
    /* Get frame from queue */
    queue_get (frame, &frame_len);
    if (frame_len == 0)
    {
        return -1;
    }

    /* Copy frame to fTo */
    memcpy (fTo, frame, frame_len);
    fFrameSize = frame_len;

    /* Presentation Time */
    gettimeofday (&fPresentationTime);
    return 1;
}

Thanks,
Priya
