After some tests it looks impossible to set one renderer across multiple different resolution screens ( at least the ati drivers refuse to group these screens ).
So I get stoped by the limitation of using direcshow one one output.
I looked at the solutions for sharing textures.
Has someone performance feedbacks about this, knowing that my goal is to use two captured hd streams ( using decklink sdi ) on 3 outputs at the same time?
Or maybe an other solution to reach my goal.
tonfilm: I tried, the texture created by the decklink node can’t be displayed
At least I don’t manage.
ft: I want to use the 2560x1600 beamer ( “main” beamer to cover the stage ).
Replacing it by let’s say 4 1024x768 machines is not a solution because of stage setup conditions.
I need two other beamers to project on spaces that will not be covered by the first one.
The production I’m working with at the moment needed the decklink input going to two output heads. We had really limited time to troubleshoot it, ended up simply using two identical intensity cards on the same feed, but I can confirm this works at least. You can address them with a getslice on the List Devices (decklink) node.
On this project I have 2 HDSDI live streams.
And 3 projectors.
That would mean 3 decklink duo and a total of 6 HD streams to capture… I’m afraid it’s going to be too heavy.
Thanks for the idea
