[vlc-devel] Re: New Patch for RTSP offset feature.

I *do not* favor including the part of this patch - in "live555.cpp" 
- that looks for the string ";offset=" in the "rtsp://" URL, and then 
uses this to determine the starting point for the RTSP "PLAY" command.

This ";offset=" hack is totally non-standard, and in general it's a 
bad idea for clients - like VLC - to be modifying or interpreting the 
contents of URLs (beyond the initial protocol,hostname,portnumber 
part of the URL).  (I realize that the Amino set-top box (RTSP 
client) implements the same ";offset=" hack, but that's no excuse for 
us to break standards also.)

If we want to be able to pass a 'starting point' parameter to VLC, 
then this should be done as a separate command-line argument (or 
something set in the GUI), *not* as a hack inside the "rtsp://" URL.
