I have to agree with Ross here.
I'm pretty disappointed to see this too. After working hard on the
original patch sets for vlc and live555 with ross, thedj, jpsaman and
blackjack from 2004 onwards and getting no traction on releases, I was
really looking forward to this being finally activated and enabled in
the 1.0 release.
There's absolutely no reason why this can't work, we've tens of
thousands of vlc installations that are patched for this and are out
at our customer sites doing rtsp trickplay against live555MediaServer
and Espial (Kasenna) MediaBase servers.
We'll be porting our platforms to VLC 1.x releases shortly, so
hopefully I'll be able to get patches out again for fixing the support
