If you need good high frame rate video, what we've done in the past is to "record" the data for each frame (possibly using animation paths, but I've not done that), and then rerun that data while capturing an image for each frame. That way even if writing the images to disk task a long time you are still getting the number of frames you need. Then, you can input the true frame rate into ffmpeg to generate the video.

You feed it frames obtained by OSG and it encodes them to an avi or whatever. Beware however that both the frame grabbing and the encoding will probably ruin your fps. ffmpeg is cross platform but has a very volatile API that can break from one version to the next... :-/ /ulrich _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/ _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
