I'm trying to interlace real time video by using the GL_INTERLACE_SGIX extension, which seems to works o.k. with glDrawPixels(), but i get a kind of an unwanted pattern when i combine both odd and even fields onto a texture. The two fields don't combine perfectly.
I'm using glTexSubImage2d() with the GL_INTERLACE_SGIX enabled, into a premade texture which is bigger than my video image.
I have a wildcat2(5110) card on a dual-P4 with Windows2000.
