Hello,
I am currently working on a multiscreen video installation. Therefor I need 8 individual Video Outputs from one Computer. Hmm. Kind of tricky, but I managed getting 8 PCI Video Cards into my computer (using a PCI expansion case) and now successfully installed 8 Video outputs to Windows (8 Sapphire Radeon 7000) VVVV was working fine with 2 Video cards before (nvidia 6600gt and radeon 7000), but since I have more cards in my computer (actually 4 Radeon and the Geforce) VVVV doesn’t start up any more.
Is there a bug with the multiscreen support I don’t know about or are there any limitations? The setup for Windows works fine with all cards and I get video output on all of them.
Does anyone have any suggestions?
we did not implement any limitations, maybe bugs, but no limitations. probably windows/directx has some. especially with pci cards this sounds plausible.
lets try to tell us in more detail what you are trying to do:
“8 individual video outputs”
you mean vga/dvi? or svideo?
which resolution each?
your cards
you say “8 PCI Video Cards” and then you say “actually 4 Radeon and the Geforce” which count up to 5 for me. you could for example also get 8 outputs with 2 highend pci-express dualheadcards whose outputs each have a matrox dualhead2go connected. but not if you need svideo out of course.
I need 8 individual s-video outputs. Thats the actual problem. I have a quad card aswell, but you can’t get 4 svideo signals out of them. And scan converters are damn expensive.
Right, I have 4 Radeons up to now, because I wanted to test with a few, because if it doesn’t work with 4 it won’t work with 8.
Geforce and Radeon mixed fine, as long as there was only one Radeon . This one was inside the Pc aswell, not in the Expansion chassis.
Since I use multiple Radeons, vvvv doesn’t start up anymore at all.
I also tried removing the geforce and using the patch with radeons only, but still, vvvv doesn’t start up anymore. All cards removed but the radeon and the geforce and … vvvv starts up again.
is there a mode where you can see at what stage of loading vvvv the programm gets stuck?
Thanks for your replies
sounds like a good idea to have a -verbose startup-flag to log the startup-process so we could probably find out the reaseon of such strange crashes. i’ll see what i can do. we don’t have such a thing yet.
but for now, roughly, when it crashes, don’t you even see the gray splash-screen? you’d say it also crashes when you start with no patch set to autoopen? or can you open vvvv with a plain patch and it only crashes as soon as you create a Renderer (EX9) node?
Hello! First of all? i want to say: joreg, you’ve the great work. v4 is geniously! About theme - have it been solved yet? I’m an interactive designer also and i’m really interested in mapping from one machine.
