Hello, I'm trying to get pictures from my webcam (toucam pro - philips) and send them to the screen using svgalib. Everything works fine, but the camera only uses YUV4:2:0 for palette, so I have to convert it to RGB24 to draw the pixels... I don't know how !! Second problem is that the picture printed on the screen is small, double, and with bad colours... is my vga.config file wrong ? or is it coming from the capture ? Thank you for any help, Vincent PS i tried the formulas : B = 1.164(Y - 16) + 2.018(U - 128) G = 1.164(Y - 16) - 0.813(V - 128) - 0.391(U - 128) R = 1.164(Y - 16) + 1.596(V - 128) but they give wrong colours...
