The VideoLAN Forums

Hello,

We tried for some time now to achieve following: we need VLC to display full-screen 4 different videos on 4 monitors, and if possible to start simultaneously

We have a windows xp pc running with a dual-core and a Matrox grafic card with 4 DVI outputs; so far no problem to run different instances of VLC each with a different content but all of it has to be done manually.

With a command line we manage to have VLC open several instances in fullscreen but cannot determine on which display (we tried --directx-device={\\.\DISPLAY4}) but it would always only open in the primary monitor. If we change the settings directly in VLC (Video>Ouput>DirectX>\\.\DISPLAY4) and open the file with the mouse, it works i mean it opens the video in the desired monitor (only with version 0.9.6. so, not in the latest), but this doesn't help since only the latest setting is saved, and we need VLC to show each separate file in a different monitor.

Has anybody an idea, a clue, a fix, or knows a programer who can help us, thank you very much in advance!

I think this needs to be fixed in the code.

Bonjour JB

What do you mean? That the command line is incorrect?

It would also helps us a bit if, after opening all 4 instances of VLC and have them dragged in the desired monitor, there was a possibility to have them start at once, simultaneously (Quicktime has a similar function "Start all instances simultaneously"), is this possible with VLC too?

No, I mean that the VLC code is broken for that.

Thank you for your response. Does it work in previous version? which version?
What was the syntaxe to display 4 screens?
My command line to open 4 instances in fullscreen in .bat file is :
vlc -f -R file1.avi | vlc -f -R file2.avi |vlc -f -R file3.avi \vlc -f -R file4.avi
Is it correct ?
Thank you

Probably some 0.8.5 or earlier.

Ok j-b, I'll try. What is the correct command line?

use start
so

Thanks for the "start" command.
What is the command line with " --directx-device={}" and the DISPLAY ?

if you just want video.

I wrote a file video.bat with these command lines, in "C:\Program Files\VideoLAN\VLC".
Files video1.avi and video2.avi are in the same directory.

cd C:\Program Files\VideoLAN\VLC
start vlc -f -R --no-embedded-video --no-video-title-show --directx-device="\\.\DISPLAY1" --no-video-deco video1.avi
start vlc -f -R --no-embedded-video --no-video-title-show --directx-device="\\.\DISPLAY2" --no-video-deco video2.avi

It works. For now I only have 2 monitors. I would try with 4 monitors when I had my second graphics card. Hopefully it works well.
Thank you very much VLC_help.

I forgot. I got tested with version 1.0.3.
