capturing video from webcam and saving to a file

Question

I am trying to capture video(alongwith audio) from a webcam.
I need to record the video and save it to a file,for further processing.
Would like to do it through CLI.

Any ideas how to do it using ffmpeg or gstreamer.

I am getting these errors:

1.gstreamer:-  erroneous pipeline: no element "xvimagesink".  
2.ffmpeg   :-  unable to find suitable output format for video4linux2.  

Any help is appreciated.

Solution

Cheese webcam studio can record Video and take photo's with effects.

As for cli recording, see if this will work

streamer -q -c /dev/video0 -f rgb24 -r 3 -t 00:30:00 -o ~/outfile.avi

ffmpeg -f oss -i /dev/dsp -f video4linux2 -s 320x240 -i /dev/video0 out.mpg

@blade19899 It seems that /dev/dsp is no more available. It is replaced by alsa. see this

Yes, the ffmpeg command results in /dev/dsp: No such file or directory on Unbuntu 2015.10. And by the way, the streamer command records in quality much lower than what a correct ffmpeg command produces.
