Yes an file watch that will update the image overlays when the file changes would be great. We can have this working on your system by Monday. Could this work on multiple images/overlays?
We have an add on to vMix that will generate a full graphic live scoreboard based on most any scoreboard system. The problem is the scoreboard overlay system outputs a constantly changing PNG file to a known directory and file. We are NOW able to read the file and overlay it over a live stream. So good so far. The problem is vMix only reads the file into its buffer once. We are constantly updating the PNG file to reflect scoreboard updates.
Is there any vMix could read the updated file by implementing a file watch?
Or is there a location we could write the PNG file directly?
Mike
BTW we got this working with Wirecast and Newtek.

Hi Mike,
I will reply here in case others want to comment on this particular feature.
Would you be ok with a simple modification of the "Image" input in vMix where it monitors the single file for changes and updates automatically?
Regards,
Martin

NOTE: this functionality will be built into vMix 10I've created a sample XAML control project below to demonstrate dynamic updating of images in vMix: http://www.vmix.com.au/download/dynamicimage.zipInstructions1. Extract dynamicimage.zip into an empty folder 2. Open vMix 3. Click Add Input and select the XAML tab 4. Browse to the dynamicimage folder and find the DynamicImage.dll file in the bin\release folder 5. Click OK in vMix The input will load with the default image which is located in bin\release\dynamicimage.png If this file is updated outside of vMix, it will be updated automatically. Modifying this projectThis project is a VB.NET 3.5 WPF User Control built in Visual Studio 2010. Programmers can modify this project to implement custom functionality according to the guidelines below: http://www.vmix.com.au/h...veloperInformation1.html

Perhaps I have misunderstood or have done something wrong.
First off, the DynamicImage.dll as XAML input only loaded the upper left quarter of the png file (vMix SD x64 9.1.0.34)
Modifying and saving the png file in the bin\release folder had no effect on the input.
Adding the XAML input again loaded the original png image again, even though it had been modified and saved with the same file name.
Note: I have recently updated to .NET framework 4.0 (does 3.5 get completely overwritten? And is that the issue? Or have I completely missed the boat on how this is supposed to work?)

I too see only the upper left quadrant of the PNG file. This is probably how the XAML stage is set up in the DLL program. We have not yet tried to modify the source. That will come in a day or to. For now this is a great step to import dynamic PNG (and xaml animations) that are changing on the fly. IceStream wrote:Perhaps I have misunderstood or have done something wrong.

The example is configured to work with 1920x1080 so you will need to set that as the output size in vMix.
Any other resolutions will require changing the project and recompiling.

So it won't work in SD currently, regardless of the PNG size?
That's basically the modification I made to the PNG, added text and resized to 720x405...
I don't think I have the wherewithal or software to change the project, what is required to do that?

Is your graphic changing that you are trying to load? If not just import it via an image. That will work fine. IceStream wrote:So it won't work in SD currently, regardless of the PNG size?

@ Sportzcast
I'm not sure I understand your question.
Importing a PNG as an image is not my issue.
Using the above XAML control project in an SD environment is, I am just trying to confirm that and ascertain whether I am able to resolve the issue on my own.
