[Live-devel] doEventLoop()

[Austin Snow]

Thanks Ross,
So there is not any way to push data (frame data) into a deivceSource?

I have modified DeviceSource.cpp deliverFrame to deliverFrame(void  
*data, int len) to pass data into it.  And in the function follows;

  if (!isCurrentlyAwaitingData()) return; // we're not ready for the  
data yet

   // Deliver the data here:
	fMaxSize = 1048576;
	memcpy(fTo, data, len);
	printf("Frame sent, len=%d\n", len);\\lets me know when a frame is  
accepted
   // After delivering the data, inform the reader that it is now  
available:
   FramedSource::afterGetting(this);

The isCurrentlyAwaitingData returns most of the time, meaning only  
about every 1.3 seconds a frame is accepted.

My input is defined and used as below;

  MPEG4VideoStreamDiscreteFramer* videoSource;
.
.
   DeviceParameters params;
   fileSource = DeviceSource::createNew(*env, params);
.
.
   FramedSource* videoES = fileSource;
   videoSource = MPEG4VideoStreamDiscreteFramer::createNew(*env,  
videoES);
	
   // Finally, start playing:
   *env << "Beginning to read from file...\n";
   videoSink->startPlaying(*videoSource, afterPlaying, videoSink);
.
.

The rest of the code is based in testMPEG4VideoStreamer.cpp

Thanks
Austin
