Description (last modified by bennylp)

Some platforms have an optimized method to switch video devices while the session is running without causing long delay or stuttering. For example, iPhone 4 allows switching between front and rear cameras while the capture session is running.

This ticket implements a capability to allow video stream to switch it's underlying device while it is running. The capability should support both capture and render device.
