WebRTC API redirection with interception techniques

Abstract:

A computing system includes a virtual desktop server and a client computing device. The virtual desktop server includes an application framework comprising a real-time media application to provide real-time communications (RTC), a native RTC engine to execute a portion of the real-time media application when received by the native RTC engine, and an API code redirection module. The API code redirection module redirects intercepted APIs of the real-time media application intended for the native RTC engine based on redirection code injected into the real-time media application so that the portion of the real-time media application is redirected. The client computing device includes a client RTC API engine communicating with the API code redirection module through a virtual channel to execute the redirected portion of the real-time media application.
