VLC is pre-installed on the frame.

OpenVR or whatever the Frame is using handles SBS video natively. Thes “steam frame theater 3D/2D” script is just a toggle switch that Steam didn’t expose (yet).

I can run an HSBS video, in VLC, with no other code downloaded or things to install, no dev mode or root required. Click the toggle for “Theater 3D” and i have a fully 3D movie on a 200+ inch screen about a foot from my face, it is so good. Done watching - close VLC, click the toggle for “Theater 2D” and it’s back to normal.
