Once everything is connected and detected, it is time to capture the video. The following command will display some known properties of /dev/video0: v4l2-ctl -device=/dev/video0 -list-inputs The Capture Process If you have more than one video input – for example, you have a webcam in addition to an Eas圜AP – and you are not sure which one is which, you can extract information from each device with the v4l2-ctl command. Video inputs will show up as files named /dev/video* (e.g., /dev/video0, /dev/video1, etc.). This will display the working capture devices detected by ALSA. To list your currently detected audio inputs, enter the command: arecord -l If you don't know what it is, you can find out by typing: pactl list cards | grep -E '|device.string' Where $card_number is the identifier of your Eas圜AP device for PulseAudio. If you prefer to work from the command line, then enter, pactl set-card-profile $card_number off To do this, use the graphical tool pavucontrol: Move to the Configuration tab and select the Off profile for USBTV007. This model does not work with the PulseAudio sound server, so you might need to tell PulseAudio to ignore the device so that ALSA can manage it instead. The USBTV007 Eas圜AP will show up as two different capture devices: one for audio and one for video. Then, make sure your operating system properly identifies the capture device. First, power up your computer and connect all the hardware as previously described.
