As far as I can tell from that, the only requirement on the HTTP source
element is to implement random access by requesting byte ranges.

souphttpsrc, neonhttpsrc and gnomevfssrc all support random access.
"Streaming via HTTP requires a custom player and the injection of
specific Flash Video metadata containing the exact starting position in
bytes and timecode of each keyframe. Using this specific information, a
custom Flash Video player can request any part of the Flash Video file
starting at a specified keyframe. For example, Google Video and Youtube
support progressive downloading and can seek to any part of the video
before buffering is complete. "
Making your player so clever as to do that as well is another issue on
which I can't really comment.
