Description
This is the DX11 version of the Blackmagic VideoInput nodes https://vvvv.org/contribution/vvvv.nodes.decklink, as discussed here video-input-from-professional-digital-cameras and here blackmagic-and-dx11-0.
For reference:
quote:eno:
... But all in all this works, also with multiple cameras. We are going through SDI, but capturing HDMI should also be possible with the appropriate cards; we're using the Decklink SDI 4K cards.
The nodes are limited to HD at the moment though. The current videoIn Node doesn't list the 4k modes ... I bet it's not a big deal to add the 4k modes. The original BM capture software offers the 4k modes.
The other thing is that the c# wrapper that Blackmagic offers for their c++ library is cueing uo frames somewhere without really telling you. We've grown some grey hair over that problem already. This is introducing an uncertain delay of some frames, unless you reset the pipeline during runteime and make sure your v4 framerate doesn't drop below the video framerate; or move capturing to a separate instance.

@eno, this has any performance drop if you send the texture to different graphic cards/displays ?
Are you experiencing that? I never tried. The Colorspace conversion is happening on GPU for sure, so if you share after that, it probably impacts the performance. The Input stream is going 'only' thru CPU though, so maybe it works well; but hinetsly I don't know how devices are handled if there are several available ...
@eno It seems to work great, much better than the dx9 version, I "feel"
thank you for these nodes! unfortunately they don't go together with the x64 CV.Image pack (which also contains the VVVV.Nodes.DeckLink.dll (EX9 Version)). any chance that this can be fixed?
videoin is red for me [decklink-dx11-red-node" "thread](https://discourse.vvvv.org/t/decklink-dx11-red-node" "thread)
Getting a lovely pink feed as there's no "YUV2RGB" in zip and the one from vvvv.nodes.decklink doesn't appear to work.
there is a texture fx in the zip !
what can i do for the missing videoin node ? dragging the plugin does not help
@eno if you post a source, it's easy to fix for new dx pack
Sorry Guys I'm tied up in a project until 12.9. No chance to find the code before.
a workaround for 4k texture is using blackspout with shellexecute, not that of a smooth experience but it works
All nodes are red in beta 35 as well as 34, as it can't find the dll, no matter where to put the files. On two different machines, what can I do wrong?
hi guys, can you give a directon for how to install this nodes, i have tried on the vvvv folders, but still on red :/, what version of vvvv you recomend to work with this node?
Is there a solution for the red nodes?
I think this contribute is outdated or only works with an older versions of vvvv and dx11pack (don't know which one)
but if it is for business: NSYNK are selling "DX11 BlackmagicDesign Decklink VideoIn" nodes in the store - /store and they usually have the good shit ;)for production.
There is also a SpoutWay: https://discourse.vvvv.org/t/blackmagic-ultrastudio-mini-recorder-videoin-everyone-ever-used-it/16022/8 https://magicmusicvisuals.com/forums/viewtopic.php?f=6&t=201
for the hardcore stuff - NSYNK for dailybread - BlackSpout
just my advice Greets CeeYaa
Thanks a lot CeeYaa ! BlackSpout works really good in my case
