I don't know much about those particular OSs, but the "LIVE555 
Streaming Media" code has been run on many embedded systems - 
especially Linux-based systems, but also some others.

The main requirements seem to be:
	- A C++ compiler (obviously).
	- Support for the 'POSIX' API.
	- Support for the 'Berkeley sockets' API, including the 
"select()" call.
"select()" is used by the "BasicTaskScheduler" implementation to 
implement an event loop.  In principle, some other mechanism - not 
using "select()" - could be used to implement an event loop, by 
defining and implementing your own subclass of "TaskScheduler".  In 
any case, though, other 'Berkeley sockets' calls - including 
"accept()", "connect()" and "bind()" - must be supported.
