[AG-TECH] Recording Access Grid Sessions

[Natalia Costas Lago]

we use the control computer as a record machine, the windows media encoder 
captures the screen and audio coming from the XAP (both local and remote), 
this way we capture the PPT + audio, if VIC is running u can even select the 
videostream with the lecturer and overlap it over the PPT. This way we have 
a wmv of our seminars, etc.

What i was trying to do now is to record the actual AG session using 
RTPdump, with this program i can record video+audio+PPT (as screenstreamer 
uses RTP), i still have two problems:
1.- The size of files as all the videostreams are recorded: I'm trying to 
solve it using RCBridge
2.- The filesize limit of the files generated by RTPdump (2GB): I've found 
some fixes done to RTPdump.c to eliminate that software limit (havent tested 
it yet).

Using this second method I can later use windows media encoder to obtain the 
wmv record of the session.

Lately i've found a program called MboneVCR, though I havent tested it yet.

Regards.
