How can I stream audio & video from one Android device to another?

[AC Question]

Ultimately I'd like to be able to mirror non-local video & audio, e.g. Youtube, from my phone to my tablet without using my very limited hotspot data. Miracast Player says it will do this but isn't working with my devices (SGH-M919 & SM-P600), I think because it doesn't support HDCP. Are there other apps that can do this? If not is there some other way to watch something on a second Android device without using hotspot?

Welcome to Android Central! You could try MirrorOp, which requires root.
