See the FAQ:

http://www.openscenegraph.com/index.php/support/faq#HowdoIcaptureascreengrab

If you want to record a video, just record the individual frames into
files and then use ffmpeg utilities to combine these into a video.

If you don't want to do that, use Google - there are plenty of screen
capture tools around (Fraps, BandiCam ...).

I just actually finished a work with ffmpeg and streaming videos from OSG rendering. You just capture the single images as Jan suggested - based on the osgscreencapture example, and then pass the captured osg::Image to ffmpeg - you dont have to do it frame by frame into file and use he offline ffmpeg utilities, you can do it directly from the code - see online samples for this, there are plenty
