stack will be removed soon in a separate CL. Constraints will not be supported in the new implementation. Apps can request a format directly and the closest supported format will be selected. Changes needed from the apps: 1. Use the new createVideoSource without constraints. 2. Call startCapture manually. 3. Don't call videoSource.stop/restart, use startCapture/stopCapture instead.
