Peer's video is landscape when in portrait orientation

[wumbo]

I'm running the app on an iPad, with a video call to the browser version running in Chrome. The video coming from the browser to the iPad is landscape, while the iPad is portrait, so there are big black bars at the top and bottom of the screen.

Is there any way to change it to portrait?

I am running my own apprtc-node-server, if that makes a difference.
