Description Splits the video output in several windows
Shortcut(s) -

You can use this module to split a video output in several small windows. This is especially useful if you want to display parts of the same video on several computers to make a big video wall.

The option --wall-element-aspect is planned to be removed from 4.0.0 to fix Bug #17433 and Bug #213. The option is redundant, and there will still be a way to select a custom ratio.

For the option --wall-active, list the integers of the windows. To select windows 2, 3 and 5 specify --wall-active=2,3,5.


  • wall-cols <integer [1 .. 15]> : Number of horizontal windows in which to split the video default value: 3
  • wall-rows <integer [1 .. 15]> : Number of vertical windows in which to split the video default value: 3
  • wall-active <string> : Comma-separated list of active windows, defaults to all default value: NULL
  • wall-element-aspect <string> : Aspect ratio of the individual displays building the wall default value: 4:3
