They 'differ' primarily in that they're completely different
implementations of a RTSP server.
In short, though, the LIVE555 implementation is a bit more complete
and somewhat more standards-compliant. Also, it has special support
(using 'index files') for seeking and 'trick play' operations when
streaming pre-recorded Transport Stream files.
The big benefit of the VLC implementation, however, is that - because
it is embedded within the VLC application - it can take advantage of
the many other features of VLC. For example, because VLC includes
encoding software, the VLC RTSP server can combine encoding and
streaming, rather than merely streaming pre-encoded files. (The
LIVE555 RTSP server implementation can also be combined with an
encoder, but it requires more work to do this.)
>Also, how hard would it be to support windows media as a stream vs. MPEG?
This is unlikely to happen, because Windows Media streaming is not
standards compliant, but instead uses proprietary protocols. (To the
extent that it uses RTSP and RTP, it does so in non-standard ways.)
