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.
Contents
Output Modules
To select one of these modules, use the -V (--vout) command line option, eg:
vlc my.avi -V caca
image
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
webcam000001.png webcam000002.png webcam000003.png ...
aa, caca
ASCII Art modules. aa displays output in black and white, caca in colour.
x11
Use Linux's X11 video output
xvideo
XVideo extension video output, a more advanced form of X11.
glx, opengl
Use OpenGL video output
dummy
Don't show output
Cloning
To display output in more than one window, video cloning can be used. To use this, specify
--vout-filter=clone
on the command line: this tells vlc to use cloning. You also need to tell vlc what output modules you want with, for example,
--clone-vout-filter=caca,glx --clone-count=2
Changing video output
If you wish to change your video output module without using the command line, here's how to proceed:
Qt Interface
- Go to tools -> preferences (or press Ctrl+P)
- Select the Video tab
- Select another video output module by changing the "Output" combo-box
- Stop any playback
- Launch the playback again
Macosx Interface
