    One simple way would be to use ffmpeg CLI tool. Suppose you have a file called 'video.avi', that you wish to grab frames from (every 10 seconds say), and save as a series of jpg files called movie_pic1, movie_pic2 etc. Then you could do something like this:

    ffmpeg -i /home/dean/Desktop/video.avi -r 0.1 -sameq -f image2 movie_pic%d.jpg

    You may use smplayer, a graphical front-end for mplayer. You can take screen shot by pressing a key.

    ffmpeg is very good I agree. I guess it puts some off being CLI, although just about everything we do in audio and video can be traced back to ffmpeg and libavcodec (the library that powers ffmpeg).

    Code:
    man ffmpeg
    will help or: FFmpeg Documentation
