After some more reading of the Live555 FAQs and archives, I
think the ProxyServer implementation will be useful for my scenario.
(Am i right about this?)
I am thinking of making the following changes in ProxyServerMediaSubsession.cpp:
. change afterGettingFrame() to input the frames to the transcoder
. change createNewStreamSource() to a new FramedSource class that gets
the Frames from the transcoder output.
For this, I need to get the next frame from the transcoder output and
give these frames as input source?
How do I make this change?
The proxiedURL stream has to wait till the (proxyURL stream +
Transcoder) has started.
How do i do this synchronisation?
In the ProxyServer implementation are the clients and server running
as different threads?
Thanks,
mugunthan
