Decklink Drivers & Cards

[Mr_P]

Have done some further testing

It seems that it IS possible to use more than one Decklink Card in a MacPro with the correct drivers

have just successfully tested a Decklink HD Extreme AND an intensity Pro - both work and allow video input on each card.

It also seems that it should be possible to use 2 x intensity/pro cards in one system. The drivers DO support it.

Will be testing HD inputs on these cards next week to see how many HD inputs are possible at one time - there may be some limitations...

These Decklink cards also work with either a Phoenix or LFG capture cards in the same system at the same time - in Standard Definition (HD tests next week)

Test system:
2007 MacPro 3.0G 8core, 8G Ram, 500G SATA, X1900XT

Simon,

I am both excited and curious. I have 2 Pro-HD cards in two different machines.

I will try my two HD cards sometime next week in one each of the 07 and 08 machines.

The only problem I think will be the latency acquired by passing the capture through Quicktime. This is still the only problem with Decklink which is why the Phoenix cards are so appealing.

Simon,

I will try my two HD cards sometime next week in one each of the 07 and 08 machines. I may also experiment with rewriting device drivers to suit Catalyst.

i dont think so... rewriting device drivers.... you dont have access to device drivers...

I have also been learning more about the core animation APIs and how devices call on the architecture.

???
core animation has nothing to do with HD cards or video input or quicktime.
decklink cards have no opengl support - so they wont accelerate any opengl stuff- and therefore will not work in any sensible way with 'core animation' or anything like it.

maybe decklink changed their drivers so that you can use an intensity and a decklink hd card at the same time -

does not mean you should - or that it works well enough.
simon has not followed up with any concrete information- so this is suspect until he does.
