Specifying Video Constraints for Android v5.x

You can customize the video capture by setting video constraints on a local video track. Setting constraints lets you optimize the video track to network and device conditions. You can set size constraints, frame rate constraints, or the aspect ratio constraints of your choice. Note that video constraints are used to resolve the capture format, but the actual video sent to a Participant may be downscaled temporally or spatially in response to network and device conditions.
