Please, I'm using the matrox meteor driver available on the k-team web page. I could compile it in a red hat 7.1 (kernel 2.4.2-2) and I could run the vcat application without problem, but the xcaptest application is not showing the image properly. The image shown is distorced and mainly blue and green. I would like to display a grayscale image since my camera is b&w. I've tried to change the VID_PIX_FLAGS to V4L2_PIX_FMT_GREY but the xcaptest still tries to display a "BGR4" image. Another problem I've found is when I try to change the parameters of xcaptest using the menu options. When I try to change the size using the menu, an error message "S_FMT in capture_size: Invalid argument" is displayed in the console. When I try to change the Standard, the message is "S_STD in capture_std: Invalid argument". I tried to compile vcat using V4L2_PIX_FMT_GREY instead of V4L2_PIX_FMT_BGR24. When the new vcat is executed, it returns the error "S_FMT returned error 2". I would be glad if someone could give me some hint to solve this problem. Valdir
