[vlc-devel] Re: RTSP trickplay support

[Ross Finlayson]

To expand upon Matthew Romaine's earlier message:

The latest version[*] (2004.12.07) of the "LIVE.COM Streaming Media" code 
(used by VLC to implement a RTSP/RTP client) includes full RTSP client 
support for 'trickplay'.  It does this using the following member functions:
	- "RTSPClient::playMediaSession()" and "RTSPClient::playMediaSubsession()" 
- which implements the RTSP "PLAY" command - includes parameters "start" 
and "end" for specifying which parts of the stream to play, and a parameter 
"scale" for specifying the speed (forward or reverse) at which you'd like 
the stream to be played.
	- If you specify a "scale" parameter other than 1.0 (the default) in 
"RTSPClient::playMediaSession()" or "RTSPClient::playMediaSubsession()", 
you should afterwards call "MediaSession::scale()" or 
"MediaSubsession::scale()" (respectively), to find out the actual scale 
factor that the server has chosen to implement for this stream.  You can 
then use this in the GUI.

"LIVE.COM Streaming Media" code:
