Google has made every single YouTube video compatible with Cardboard. (The company says videos that weren’t shot with VR in mind will look like you’re watching them in a personal Imax theater.) To let people live-stream 360 videos, YouTube has partnered with VR camera makers and VR software firms. Youtube also said it’s making the audio for nonlive videos on the YouTube Android app more realistic rolling out 3D audio. The features will allow the video platform to go head-to-head with Facebook, which is making a grab for the VR market with the launch of a 360° camera and a content hub for it, which it unveiled last week. The format allows PC users to use a mouse to adjust their perspective.
