Media Texture Performance in VR
Is there any way to get HD and better yet, UHD resolution video to play back in VR smoothly? I get juddering performance issues when HD video is played back in VR. I'm using 360 panos, so I'm mapping the video to a sphere. Ideally, I'd like to use UHD stereoPano video with the screenPosition node to play back nice stereoPanos in UE4. But I can't even get a normal HD video to play back in VR without juddering.

Not yet. We are working on this, but progress is a bit slow due to GDC preparations. I'm not sure if it will make it into 4.12. Might not be ready until 4.13.
Update: Please try the latest code in the Github Master branch and see if that improves things. There have been a number of performance improvements. In particular, on Windows I eliminated one buffer copy, and the pixel conversion happens on the GPU now,

4.13 (preview) 360 video is possible...and quite good...(4k @30fps , at least)
Would Still love to be able to invert the media texture (due to mapping it to the inside of a sphere, using 2 sided texture) - without to much of a performance hit...but things are looking really promising...

I am also trying to play a 360 Video on a sphere. At first I had some juddering and my FPS were below 7 or so. So my workaround now is to cut the sphere into 12 pieces and set them all into one Blueprint actor. With this i get now about 30 FPS. I have inverted my media texture just by applying a textureCoordinate and set the U tiling to -1.
One question I still have: what is the max resolution the Media Player can work with? I have tried to find something in the internet but wasn't succsessful at all :/
