Hi, First, thanx for this great work, I'm using MLT with the Kdenlive frontend to edit video (mainly avchd) and it does its job quite well. But even with low res video (i use kdenlive's "proxy clip" feature), adding a simple effect like contrast makes the preview to drop frames. I sure don't have the strongest cpu around but i think a E8500 is not so bad. I've recently played a bit with opengl and found that a simple nvidia GT220 can run several glsl filters (say 6, like contrast,brightness...) on a 1920x1080, while still displaying 50fps (deinterlaced 25i) ! So you can imagine what could be done on lowres ! Having a flawless preview is really comfortable :)
I see that opengl is in MLT's todo. So i wonder if you have already some thoughts on what should be done and how it should be done. I would be happy to help. -- Christophe Thommeret ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Mlt-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mlt-devel
