| Description | change the video's alpha channel |
| Shortcut(s) | - |
This filter can be used in the mosaic framework to set a video's alpha channel (or transparency) based on a PNG image's alpha channel. You can thus blend only parts of the mosaic substream on the background.
- alphamask-mask <string> : PNG file to use as a mask. The alpha channel only will be used to build the mask. This image needs to have the same size as the video it will be used with.
Example use:
% vlc -I telnet --color -vvv --vlm-conf mosaic.vlm --mosaic-width 360 \ --mosaic-height 270 --mosaic-rows 6 --mosaic-cols 6 --mosaic-keep-picture \ --fake-file ~/images/mire.jpg --fake-width 360 --fake-height 270 \ --no-audio --sub-filter mosaic
And the vlm config:
new channel0 broadcast enabled
setup channel0 input /home/dionoea/media/redefined-nintendo.mpg
setup channel0 output #duplicate{dst=mosaic-bridge{id=0,height=270,width=360,mask=/home/dionoea/images/cone_360x270.png},select=video,dst=bridge-out{id=0},select=audio}
new background broadcast enabled
setup background input fake:
control background play
control channel0 play
The files used are available on http://people.videolan.org/~dionoea/mosaic/ if you want to test. (This will blend the redefined nintendo video in a cone like region)
