Hi! I have tried to use OpenCV's samples that use camara, but it didn't work. I tested my webcam with the program Cheese and it's OK. I have installed some packeges too:
sudo apt-get install libtbb2 libtbb-dev sudo apt-get install libavformat-dev libwscale-dev
After that I rebuild my OpenCV in this way: cmake-gui I selected "BUILD_EXAMPLES" I clicked in "Configure" I clicked in "Generate"
Unfutunally, anything working. I'm testing the sample bgfg_segm. I can use the video but the camara. What can I do?
