Hi guys,I have found a few issues: 1- Repos Access Instructions Wrong: I can not download the repository with the commands listed in the online instructions at (http://groups.google.com/group/microdia/web/ testing-microdia-driver-draft): $ git clone http://repo.or.cz/r/microdia.git error: Can't lock ref $ git clone http://repo.or.cz/microdia.git Cannot get remote repository information. Perhaps git-update-server-info needs to be run there? I have to change the http: bit to git: then it works $ git clone git://repo.or.cz/microdia.git 2- Driver Doesn't Work Anymore: My webcam is 0c45:6270 Microdia U-CAM PC Camera NE878, I used to be able to use this driver on an older machine with kernel 2.6.18 but it has since died and I moved to a machine with 2.6.24 kernel. I have successfully compiled and load the module (using both the old source code I used last year, and the lastest microdia source code) on this new kernel, however nothing works. On module loading dmesg show every OK: -- sn9c20x: SN9C20X USB 2.0 Webcam - 0C45:6270 plugged-in. sn9c20x: Detected MT9V011 Sensor. sn9c20x: Webcam device 0C45:6270 is now controlling video device /dev/ video0 sn9c20x: Using yuv420 output format usbcore: registered new interface driver sn9c20x sn9c20x: SN9C20x USB 2.0 Webcam Driver v2009.01 loaded -- Howerver tests with mplayer (as instructed in online instruction above) has this error: -- $ LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so mplayer tv:// -tv driver=v4l2:width=640:height=480:fps=25:device=/dev/video0 -vo xv ...
