This camera is able to support banding filter and a few other useful features. These features are correctly supported by V4L API (see V4L2_CID_POWER_LINE_FREQUENCY, V4L2_CID_BAND_STOP_FILTER, ... ). However, mxc_v4l2_capture only forward a few subset of V4L controls to camera driver (see mxc_v4l2_s_ctrl() in mxc_v4l2_capture.c). Should I patch mxc_v4l2_capture.c in order to support them, or I have missed something?</P></BODY></HTML> Thu, 30 Apr 2015 13:36:07 GMT jérômepouiller 2015-04-30T13:36:07Z Advanced controls of CSI camera https://community.nxp.com/t5/i-MX-Processors/Advanced-controls-of-CSI-camera/m-p/392855#M57349 <HTML><HEAD></HEAD><BODY><P>Hello,</P><P></P><P>I add support for OV7742 (plugged on CSI port) on kernel 3.10.17.
