ffmpeg/libav works well for capturing input from webcams, at least if
the driver uses the video4linux (v4l) framework (I haven't encountered
any other kinds). For instance, to capture one frame and store it as a
png image (using libav's avconv, ffmpeg would be similar), you can use
avconv -f video4linux2 -i /dev/video0 testframe.png
mplayer (and its descendants) also play well with v4l, to directly
display the webcam's input you can use
mplayer -tv driver=v4l2:device=/dev/video0 tv://
(The -tv switch and its argument are probably redundant as the default
detection is very good.)
