WebRTC API redirection with fallbacks

Abstract:

A computing system includes a virtual desktop server and a client computing device. The virtual desktop server includes a real-time media application to provide real-time communications (RTC), a native RTC engine, and an API code redirection module. The API code redirection module redirects original APIs of the real-time media application so that a portion of the real-time media application is to be redirected. The client computing device includes a client RTC API engine reporting to the API code redirection module on capabilities of the client computing device to execute the redirected portion of the real-time media application. The API code redirection module switches to a fallback mode if the client computing device has limited capabilities. In the fallback mode, original APIs are used so that the native RTC engine executes at least part of the portion of the real-time media application.
