[Live-devel] Mechanism of passing data from source to sink

[Alan Martinovic]

Hi,
I've read how the control flow mechanism works (http://www.live555.com/liveMedia/faq.html#control-flow)
and I'm trying to get the idea of how it works in practice by following the Elphel example (http://www.live555.com/Elphel/).

I've traced the actual payload to the fTo variable

#ElphelJPEGDeviceSource.cpp 95-96
// Then, the JPEG payload:
fFrameSize = fread(fTo, 1, fMaxSize, fFid);


But when grepping through all the *Sink* and *Session* files, I found no traces of fTo. Plus, the fTo is protected.
At first, I was thinking that when triggered, the JPEGVideoRTPSink was getting the raw data by accessing the FramedSource.fTo and then adding the RTP headers to that data (which represent raw video).

By which method (variable?) do sinks and sources actually share the raw video data?
