Hello, I have an LCD video-projector, and as on almost all video-projector, the 3 matrix are not perfectly aligned (or maybe it is related to optical diffraction ?) but there is a shift (less than 1 pixel) between red, green and blue. The resulting effect can be seen on the following photo: http://www.gemibox.net/upload/rgb_shift.jpg I'm used to Windows, and there are 2 ways to get rid of this problem: either using Haali renderer that can shift cyan and magenta, or using Media Player Classic and a custom Pixel Shader filter that do almost the same (but with R, G and B) using the graphic card. An example of pixel shader code to do this can be seen here: http://pastebin.com/dMs33c99 I looked on Google but could not find any way to do this with mplayer? Would it be difficult to develop a new filter? Regards, Yann Pomarede.
