How to record videos in VR?

hello, I want to record videos in VR as in without any external applications, so it needs to be an asset. I don't need nothing fancy just GPU encoder capable of doing 360p 24fps videos. Recording videos is going to be a mechanic into the game so I need a really stable solution.

I'm really struggling finding the recording solution that wouldn't lag the game. Already tried AV ProMovieCapture without any luck- it lags the game out too much.

 

Have you had a look at the Rock VR Plugin?
