Tool/software:
Hi,
I'm using rewrite an app using the capture node, the camera is ar0233, and it seems ok, but when i write the output image of capture node,it seems that the capture node doesn't work normally. It output the picture like bellow,did i miss some configuration of the capture node?
more information:
1.sensor set:
vx_status set_front_cam_defaults(SensorObj *frontCam)
{
vx_status status = VX_SUCCESS;
strcpy(frontCam->sensor_name, "AR0233_MAX9295_UYVY");
frontCam->num_sensors_found = 0;
frontCam->sensor_features_enabled = 0;
frontCam->sensor_features_supported = 0;
frontCam->sensor_dcc_enabled = 0;
frontCam->sensor_wdr_enabled = 0;

frontCam->usecase_option = APP_SENSOR_FEATURE_CFG_UC0;
frontCam->is_interactive = 0;
frontCam->sensor_out_format = 1;
status = app_querry_sensor(frontCam);
return status;
}
2.
Camera start ok.
