A computing system includes an input driver and a virtual input controller. The input driver is configured to receive input data from a first controller of a recognized data protocol and to provide the input data to an API of an application to control actions of a first participant in the gaming application. The virtual input controller is, in contrast, configured to receive input data from a second controller of a protocol incompatible with the input driver, translate the input data to the recognized data protocol; request a broadcast application identifier for a currently-broadcasting application from the broadcasting agent, and provide the translated input data to the input driver in association with the broadcast application identifier for controlling actions of a second participant in the application via the API of the gaming application.
