hi,
i use mt9p031 and dvi board with leopard board.
i run gstreamer pipeline example in https://www.ridgerun.com/developer/wiki/index.php/LeopardBoard_365_GStreamer_Pipelines_-_SDK_2011Q2
gst-launch -e v4l2src always-copy=false ! video/x-raw-yuv,format=\(fourcc\)UYVY, width=1280, height=720, framerate=\(fraction\)23/1 ! dmaiaccel ! dmaiperf ! TIDmaiVideoSink videoOutput=DVI sync=false accelFrameCopy=true videoStd=720P_60
i get
