Video Play flat(not 360/180) stereo video in unity

Hi all,

I've been trying to play a flat stereo video (top-bottom) using the video player component. Using the Standard shader, it displays the entire top-bottom video instead if just one eye as expected since there are no stereo settings. The skybox panorama shader has options to play stereo video but it only supports 360/180 video. I tried using 3d render texture but none of the built in shaders seem to support it. Looks like I need a shader that can display a 3d render texture.

Any help is appreciated!
