yes, that does improve performances. i hope using pix_movie + shader will be ok.
working with shader make strange things with texturing mode : when i start a patch, i have to send a mode 0 to pix_texture in order to see anything. so, i can't work with pix_movie instead of pix_film when i use shader.
So you can play 10 DV clips now?
regarding the codec, i can have from 2 to 8 DV film on the same time (with shader / pix_film). 8 is not that bad, i think it will be ok.
The shaders will work but performance can still be a problem. Pixel shaders are far from 'free' operations. A moderately complex shader applied to a few quads stretched to 1280x1024 or higher can be slow. The more pixels your texture uses on screen the more work the shader has to do. It is not fixed to the size of the texture you upload.
yes, this is obvius regarding the way pixel shader work. but i did not do complex operation (removing the sky from movies of clouds). (in fact, there is less computing in the processing i'm doing than computing complex lighting on a white square).
thanks a lot for your help.
