Decklink IDL Files in Labview 2011

[dkennedy2010]

Hi,

I am trying to write code for a Black Magic Decklink Extreme HD in Labview.  The problem is that I can only find .idl files and I don't know how to access/use them.  Is their a tutorial that can help?  I found one, but it was using Labview 7, so it wasn't very helpful because I could not find IDLDraw anywhere.  Is it obsolete?  I also read that I may be able to use IMAQdx, but I don't even know how to do that.  Any help would be appreciated as I do not even know where to start.  Thank you so much for any help.

Hi Donald,

I won't be able to help you much with the Black Magic Decklink, but I will be able to answer questions about IMAQdx.  IMAQdx is a vision acquisition driver that is capable of working with DirectShow compatible USB, firewire, and GigE vision cameras.  From doing a quick search, it looks like this board is indeed DirectShow compatible.  You can download http://joule.ni.com/nidu/cds/view/p/id/2625/lang/en and see some information on using the driver here: http://www.ni.com/pdf/manuals/371970a.pdf

The IMAQdx driver normally is used with DirectShow USB cameras, so I'm not sure how it will work with your board.  Also, keep in mind that the IMAQdx driver will need to be licensed for continued use beyond a trial period.  I hope this information helps!

Thanks Cole R.  I will have to look into it. 

nyc, I have already looked into this and didn't find any  good information.  I am going to join that forum, but wanted to see if anyone from the Labview community has worked with .idl files.

How am I supose to use the API?  I am not familiar with it.  Thanks.

I have figured out how to use the Decklink card, though it is not with the .idl.  If you have IMAQdx, you will be able to configure and see the card via MAX because it uses DirectShow.  You can grab video, but I do not believe you can use all the features of the card directly through MAX.  The people at BlackMagic told me that you can write a wrapper.  The example code is on the Linux side, but I have not really tried that option.  I believe you have to write a C wrapper for it.

I hope this helps anyone that needs it.  IMAQdx is available through the Vision Development Module Toolkit.
