[Live-devel] Live555 Streaming from a live source

[Sagi Ben Moshe]

Hi Ross, 

Ok, we used the StreamParser class and probably this cause the problem we
have. 

This is our Device class 

class CapDeviceSource: public FramedSource {

We are trying to stream MPEG4 (Later on we will move to H.264) 

What is the best class to derive from instead of FramedSource in order to
use DiscreteFramer downstream object? 
 
If I understood you correctly it is MPEG4VideoStreamDiscreteFramer and we
should implement the function doGetNextFunction but looking on the code we
thought it is best to implement the function afterGettingFrame1, yet it is
not virtual so probably we are missing something. 

Thanks,
Sagi

This is true only for the "StreamParser" class, which you should
*not* be using, because you are delivering discrete frames - rather
than a byte stream - to your downstream object.  In particular, you
should be using a "*DiscreteFramer" object downstream, and not a
"*Framer".

What objects (classes) do you have 'downstream' from your input
device, and what type of data (i.e., what codec) is your
"DeviceSource" object trying to deliver?  (This may help identify the
problem.)
