(ALSA is the audio manager in RaspberryPi) $ arecord -l The command arecord -l will give us the list of ALSA devices. The -d0 parameter indicates on which device the modifcation should be applied (if you ahve several cams or its device name changed) v4l2-ctl -d0 -set-ctrl=led1_mode=0 The last 2 lines gives us clues to control the built-in LED indicator, for instance, to deactivate the LED indicator. Led1_frequency (int) : min=0 max=255 step=1 default=0 value=0 Led1_mode (menu) : min=0 max=3 default=3 value=3 Sharpness (int) : min=0 max=255 step=1 default=57343 value=128īacklight_compensation (int) : min=0 max=1 step=1 default=57343 value=0Įxposure_auto (menu) : min=0 max=3 default=0 value=3Įxposure_absolute (int) : min=3 max=2047 step=1 default=250 value=333 flags=inactiveĮxposure_auto_priority (bool) : default=0 value=1 White_balance_temperature (int) : min=2000 max=6500 step=1 default=57343 value=4822 flags=inactive Power_line_frequency (menu) : min=0 max=2 default=2 value=2 White_balance_temperature_auto (bool) : default=1 value=1 Selection: crop_default, Left 0, Top 0, Width 1920, Height 1080 V4l2-ctl -all lists all available devices and their config $ v4l2-ctl -allīounds : Left 0, Top 0, Width 1920, Height 1080ĭefault : Left 0, Top 0, Width 1920, Height 1080 Once everything is installed, you can configure your C920 webcam. You can install them with the following commands : sudo apt-get install vlc VLC which is not only a video player, but also has powerful streaming capabilities.
It offers the command v4l2-ctl which will allows us to control and config the webcam. You should see: No LSB modules are available.ĭescription: Raspbian GNU/Linux 9.4 (stretch) The answer is working with Raspbian 9.4 Stretch.Ĭheck your version with the following command : lsb_release -a Additional commands : infinite loop recording & split videoħ.
(If you have no existing network to connect your Pi to)Ħ. One can also see the all-in-one solution prototype on RaspiVWS project homepage (for curious people, see GitHub project)Ĥ. Using this method, the RaspberryPi3 is always around 5% CPU. This solution is tested and working with versions indicated below.
