Hi all, We've made an ImageStream using FFmpeg to display movies on textures, but I am currently facing some problem when displaying this movie on two different contexts. Here is my setup :
WinXP with one GForce 8600GTS and 2 screens, viewer on DrawThreadPerContext mode (OSG SVN head version). When I only have one screen but two windows (with a different context per window), everything works fine, the movie is displayed on the 2 windows without any problem. When I plug a second screen, and I keep the same setup (2 windows rendered into the first screen), I have a huge frame drop (more than 20 fps) when rendering my movie (note that in this configuration, nothing is displayed on the second screen). Same thing happens if I use the 2 screens (with each window in full screen mode on each screen). I really don't understand why adding a new screens make this difference, moreover it's the only thing in my application that suffer like that from the second screen. Does it ring a bell to someone ? Thanks in advance ! -- Serge Lages http://www.tharsis-software.com
