Hi all,
I'm having a trouble with a decklink card and a GMFBridge controller.
All was working right till yesterday.
I had a gmfbridge controller registred in my computer, then I sed that a newer
version of the controlled was released (v.1.0.0.18) and then I've downloaded
that, I've unregistered the older version, and I've registered the newer one.
the problem was that the newer one isn't a valid COM class, maybe the dll is
corrupted.
I've unregistered the newer version, I've replaced that with an older
(1.0.0.15), and I've registered it.
Now I'm not able to build a render graph using my Decklink video render
filter.
If I connect the GraphEdit to the render graph, I can see the decklink filter
unplugged and a "video render" plugged as the output.
Have you some ideas for that?
Have you some link to download a newer version of the gmfbridge.dll (not the
gdcl site).
Thanks in advance.. Maurizio

GDCL writes GMFBridge. Even if you found one elsewhere, I would be reluctant
to use it.

Have you tried running the samples that come with the DLL? Do they work correctly?

GDCL includes the source to GMFBridge. Have you tried debugging it?

Have you tried talking to GDCL?

Hi Snarfle,
I've tested the GMFVBPlay example and, yes, it works.
The problem is that my app is working too. I'm not able to output to my
decklink card, when I build the render graph, I insert the decklink filter
into the graph (and I can see it by GraphEdit), but it isn't plugged, and,
instead of that filter, a standard rendered is added and plugged to the render
graph.
I suppouse that the problem is GMFBridge controller because all the problems
were born when I've tried to unregister the older version and register the
newer one.
Anyway, in the next 2 hours I'll be able to have a tested version of GMFBridge
controller andalso a running version of my app.
I will be able to know the problem.
Thanks again... Maurizio

Ops, I forgot an info.
Building a single graph, with a decklink as the renderer and using the same
video files used into the app with the GMFBridge controller, the decklink card
outputs the clip in the right way.

Solved!
I've donwloaded the 1.0.0.17 version of the GMFBridge.dll, found in the GDCL
website, and now all is working right.
Thanks again, Maurizio
