Spout DX11 receiver cannot receive image from Spout sender from UE4 about spout2

I read the similar issue of U3D plugin. Looks like something related with the UE4 plugin. :(

I have been working on the DX11 examples a little while back for another project and found the same problem. It's a tricky one. Both UE4 and U3D use a DirectX11 texture created by the application. The Tutorial07 example copies the sender's shared texture directly (instead of by way of the OpenGL/DirectX interop) and uses that texture as a shader resource view. There are limitations for a shader resource view such as matching format. The first question is - in your own application are you using the received texture as a shader resource view? I will have to refresh my memory of the project work before I can suggest anything more.

[ericdlee]

Yes. Same as tutorial07.

I have uploaded a test executable for Tutorial07 for you to try with UE4 -
https://github.com/leadedge/Spout2/tree/beta/SPOUTSDK/Examples/DX11example/Binaries
If it works I will update the Spout SDK and SpoutDX class.

Sorry the new testing executable show black image. :(

[leadedge]

At least it's different. I am not sure what I can do without any means to test and work with this. I will give it a little more thought.

Thanks for your kindly support. I will also update if I find any clue in UE4.

I think it's something to do with the creating the shader resource view, it seems to be something to do with formats, but there could be more to it.

A while back I had a similar problem with a DirectX 9 sender where the texture format was not compatible with another program. I made a bridging program which solved the problem. This might work for UE4 and get you going. Contact me by email for details.

For readers with a similar problem, contact me via email. There is a bridging program that allows a workaround. I have not been able to find the underlying cause but will keep it in mind.
