Video can be captured with the tool avconv:

Example 1 (capture and store a MJPEG video):

avconv -f video4linux2 -pix_fmt yuv422p -s 1280x720 -r 25 -i /dev/video0 -c:v mjpeg result.mov

Example 2 (capture and stream as H264 or MPEG2 video):

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

Example 3 (capture one frame and store as picture):

./capture -d /dev/video0 -f -o -c 1 > video_1f.uyvy
convert -size 1280x720 -depth 16 -sampling-factor 4:2:2 ./Desktop/video_1f.uyvy ./Desktop/video_1f.png

Example 4

./capture -d /dev/video0 -f -o -c 10000 > file.img
