David,

As a starting point, you will need to write a new 'source' class that 
encapsulates video frames from your capture device.  For a model on how to 
do this, see "liveMedia/DeviceSource.cpp".

Before I can give you a more detailed response, can you tell me:
- Does your capture device capture video frames only, or both video and audio?
- Does your capture device capture MPEG-1, 2 or 4 video?  And does it 
capture discrete video frames, or does it capture an arbitrary (unframed) 
sequence of video data?
- Do you want to stream via multicast (e.g., as demonstrated by the 
"test*Streamer" demo applications), or via unicast on demand (e.g., as 
demonstrated by the "testOnDemandRTSPServer" demo application)?
