Output NDI® from your Avalonia application!
A crude port of the WPF sample code from the NewTek NDI® 5 SDK.
This library provides a NDISendContainer Avalonia component
In the sample, I have wrapped the NDISendContainer itself within a ViewBox, which seems to ensure that the rendered output frames remain at the expected size and resolution.
The code of NDILibDotNet2 is based on the NDI SDK C# sample code, with the WPF dependencies removed so to target .NET 5
I have not done much testing. This code is likely wildly inefficient. I have not tested audio yet.
But it does work well enough to send out frames correctly, with alpha channel - pretty cool!!
From a cursory glance, performance is quite acceptable... it can only improve from here, right? :) :) :)
