The "LIVE555 Streaming Media" code does not include any codec (i.e., 
encoding or decoding) software.  Therefore, if you want to stream 
audio, you will either need to stream raw PCM audio from your input 
device, or else write your own filter class to encode this to some 
other (lower-bandwidth) format.

No, there's currently no support for the "uncompressed video" RTP 
payload format.  Again, you would need to write your own filter class 
to encode this to (e.g.) MPEG-4 video.
