    Abstract: A computing system includes a video source to provide a video stream and a virtual desktop server. The virtual desktop server includes a media application to provide media streaming that includes the video stream and an overlay on the video stream. An accelerated content redirection module redirects a portion of the media streaming by providing a placeholder to indicate positioning geometry of the video stream within a media window, with the placeholder to include the overlay. Providing the placeholder includes providing a first color for an underlay of the placeholder at a first time, and providing a second color for the underlay of the placeholder at a second time. A geometry tracking module detects the placeholder and determines positioning geometry associated therewith, and determines a color and an alpha blending factor of the overlay based on calculations involving the first and second colors for the underlays of the placeholder.

    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.

    Abstract: A computer system is provided. The computer system includes a memory, a network interface, and at least one processor coupled to the memory and the network interface. The processor is configured to intercept a request transmitted by an application hosted within a virtual computing session, the request being a request to be authorized to access a resource; pass the request to a virtualization agent hosted outside the virtual computing session; receive a response to the request, the response including a credential granting authorization to access the resource; and pass the response to the application to authorize the application to access the resource through use of the credential.

    Abstract: A virtual desktop server include 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, and a processor coupled to the application framework and to the native RTC engine. The processor redirects original application program interfaces (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 to be redirected. The processor receives from a client computing device capabilities of the client computing device to execute the redirected portion of the real-time media application. The processor switches to a fallback mode if the client computing device has limited capabilities.

    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) for peer-to-peer networking, and a native RTC engine to execute a portion of the real-time media application when received by the native RTC engine. An API code redirection module redirects intercepted APIs of the real-time media application so that the portion of the real-time media application is redirected away from the native RTC engine to a client RTC engine in the client computing device. The portion of the real-time media application being redirected includes provisioning information directed to a remote media server. A network location service provides provisioning information directed to a nearby media server. The client RTC engine executes the redirected portion of the real-time media application, and selects the remote media server or the nearby media server based on network proximity to the client computing device.
