Trying to get the pi cam working with open cv per http://thinkrpi.wordpress.com/2013/05/22/opencvpi-cam-step-5-basic-use-display-a-picture/. Finally have the program built, but now I get this:
pi@raspberrypi ~/camcv $ ./camcv mmal: main: Failed to create preview component mmal: Failed to run camera app. Please check for firmware updates
I've done sudo apt-get upgrade/update, sudo rpi-update, and ensured camera was enabled within raspi-config. I can capture images with raspistill well enough, although apparently I can do this even with the camera not enabled in raspi-config. Any help is appreciated.
