Port spout to VK_External_memory about spout2

[leadedge]

Using Spout with Vulkan is possible by interfacing a Vulkan image with a DirectX 11 texture.

I am not familiar with Linux but if it's possible to use DirectX 11 and if shared textures are supported then it might be easier to use that directly. Applications can already use a sub-set of the Spout SDK classes to do this and there has been some progress with it, as you can see in the beta and develop branches. Is this a possibility?

So there is no directx on Linux, Vulkan is really where everything is headed. So it would require swapping any directx implementations with their Vulkan alternatives.

I understand that sharing Vulkan images directly using external memory can be done and combining with the existing Spout sender name system would be the way to investigate this.

There would need to be some synchronisation mechanisms but I expect that could be sorted out.

But I am afraid that's some time off for me to find the time and gain the expertise to do so. Meanwhile the only solution is with shared DirectX textures if there is any possibility for you there.

I may fork the repo and better understand the code base, I’m thinking I may be able to play with the API and see if textures can be easily copied.

You might be best to go straight to the Develop branch and look at the "Basic" DirectX examples for the low level workings. The SpoutDX support class is designed to make things easier.

Let's keep this option open for the future, but for now I can't immediately help with it. If you come to any potential solution, please email using the contact on this repository overview page.
