A large part of my work is writing about and sharing the Vuo story. We believe there are all kinds of people who will embrace Vuo once they discover it’s out there. So, my efforts include helping create the Vuo website, writing press releases, submitting conference proposals and generally figuring out how to create excitement and how to spread the word about Vuo. I occasionally help out with Vuo e-mail support and I'm part of the think-tank called "Team Vuo."
I'm not sure why it is not working for you. Does it work if you drag just the composition in? If so, and you want to be able to change the URL within VDMX, you can set that up by adding a URL published port that VDMX will see. You can then change that within VDMX. See the attached.
We've found an issue where Vuo's image generator protocols need to use the image width and height input ports when outputting an image or movie in VDMX.
I added a Resize Image after the Play Movie node to take each movie frame and resize it using the width and height data from the image generator inputs. The resized image output cable then goes to the image generator outputImage port. This allowed the movie to play within VDMX.
We've fixed this issue in the current version of Vuo, but VIDVOX needs to update VDMX to Vuo's current version in their framework first. For now, using Resize Image will avoid the issue. Also, no need to use both an Allow First Event and Fire on Start. The Allow First Event is sufficient.
