For vedio recording in linux, mplayer alone may not be enough, one additional package that comes with mplayer is needed. Its mencoder. To install mencoder in a debian based distro use the command
$sudo apt-get install mencoder
For other distros like redhat you can use relevant tools like YUM to install mencoder.
Then for vedio recording follow the commad below
Video Recording Without Sound
$ mencoder tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0 -nosound -ovc lavc -o filename.avi
