-Video can be captured with the tool ''avconv'': \\ +
- +
-**Example 1 (capture and store a MJPEG video):**\\  +
-<code bash> +
-avconv -f video4linux2 -pix_fmt yuv422p -s 1280x720 -r 25 -i /dev/video0 -c:v mjpeg result.mov +
-</code> +
- +
-**Example 2 (capture and stream as H264 or MPEG2 video):**\\ +
-<code bash> +
-avconv -f video4linux2 -pix_fmt yuv422p -s 1280x720 -r 25 -i /dev/video0 -c:v libx264 -f mpegts udp://192.168.0.16:6000 +
-avconv -f video4linux2 -pix_fmt yuv422p -s 1280x720 -r 25 -i /dev/video0 -vcodec mpeg2video -r 25 -f rtp rtp://192.168.0.16:1234 +
-</code> +
- +
-**Example 3 (capture one frame and store as picture):**\\ +
-<code bash> +
