[Live-devel] ByteStreamFileSource afterGetting function problem

[Engin Kurutepe]

Hello all,

I am working to make my H264RTPStreamFramer use asynchronous read 
operations. Here is a snippet of code that i'm using:

void H264RTPStreamFramer::doGetNextFrame()
{
	if ( ! isCurrentlyAwaitingData() ) return;
	char first_byte = packetBuffer[0];
*	fInputSource->getNextFrame(packetBuffer, 20,
				   afterGettingHeader,
				   this,
				   handleClosure,
				   this);
}

void H264RTPStreamFramer::afterGettingHeader(void* clientdata,			  		 
unsigned frameSize,							        unsigned numTruncatedBytes,						 
struct timeval presentationTime,
			unsigned durationInMicroseconds )
{
*	H264RTPStreamFramer *framer = (H264RTPStreamFramer*)clientdata;

	if(framer == NULL)
		return;

	framer->afterGettingHeader1();
}

fInputSource is a ByteStreamFileSource. There are two breakpoints at the 
lines marked with *. FramedSource::afterGetting(this) is called inside 
afterGettingHeader1(), which also does some parsing on the header. The 
Problem is that the second breakpoint is never reached. And the program 
quits with the following error message:

	BasicTaskScheduler::SingleStep(): select() fails: No error

Does that mean that fInputSource never finishes reading the 20 bytes 
from the byte stream?

Thanks a lot,
