Fullscreen over 4 Displays ?

Postby pulse00 » 12 Nov 2007 19:32

Hi,

i am working on a project where i would need to play a huge
video (4096x768) over 4 screens, each having a resolution
of 1024x768. The hardware i have to work with is an
ATI FireMV 2400 pciE.

Does anyone know if this is possible somehow with
vlc player ? if not, does anyone probably know
a software which could accomplish that ?


thanks!

there is the "wall" plugin that is probably what you are looking for: it splits the video in several outputs, and then you are free to put these on the monitors you want :)

have a look at "vout filters"

thanks for your reply.

I was just playing around with the wall plugin, unfortunately without success.

No matter what settings i use from the commandline, the window behaviour stays the same.

I'm not sure if i understand you right, though. Does this plugin create several seperate windows
which i can manually place on another screen ?

run vlc --vout-filter wall video.ext

the options are:
--wall-cols <integer> Number of columns (default 3)
--wall-rows <integer> Number of rows (default 3)

You can also use the "panoramix" filter (with the same principe and define 0%for length of overlapping area ...) in 0.9 version.

If you use Windows OS with 4 displays, this filter spawn automaticaly the four windows on the four displays (if you set video-width & wideo-height at the resolution of your displays ...). Linux version is little buggy (depend of xinerama, merged X11 option ...)

Second difference between "wall" filter is the soft edge-blending feature.

You could also mess around with the aspect ratio and crop video settings to make the images fill the individual screens.
