Hi,
I am trying to understand and modify one of the testProgs - testOnDemandRTSP
Below is how I understand the flow (pardon my lack of OOD understanding)
testOnDemandRTSPServer -> ServerMediaSession ->
MPEG4VideoFileServerMediaSubsession -> FileServerMediaSubsession->
ByteStreamFileSource
Instead of using a file as an input source I would like to use the
output of a "blocking function", which gives one output MPEG4 frame
every call. This function captures a V4L2 frame from a capture device
and encodes it into a MPEG4 frame. Which is the right point where I
should insert this blocking function ?
You should first write your own subclass of "FramedSource" that
encapsulates your capture device. (See "DeviceSource.cpp" for a
model of how to do this.)
Then, you should write your own subclass of "ServerMediaSubsession" -
that uses your new 'capture device' class (instead of
"ByteStreamFileSource") - and use this in place of
"MPEG4VideoFileServerMediaSubsession".
