VideoLAN comes with a selection of Video Output modules. These can display output on almost any computer.

If you don't want any video, you can use the --no-video option.

Output Modules

To select one of these modules, use the -V (--vout) command line option, eg:

vlc my.avi -V caca


Save all the frames of a video as a sequence of images. You can select the output format using --image-out-format (currently you can only choose png), and the start of the file name with --image-out-prefix. Finally, to create an image once out of a number of frames, give that number to --image-out-ratio. For example,

vlc v4l:// --image-out-prefix=webcam --image-out-ratio=20

will create a series of images named


aa, caca

ASCII Art modules. aa displays output in black and white, caca in colour.


Use Linux's X11 video output


XVideo extension video output, a more advanced form of X11.

glx, opengl

Use OpenGL video output


Don't show output


To display output in more than one window, video cloning can be used. To use this, specify


on the command line: this tells vlc to use cloning. You also need to tell vlc what output modules you want with, for example,
