Abstract

A system, computer-readable storage medium storing at least one program, and a computer-implemented method for obtaining video streams is presented. A device-agnostic request to obtain a video stream is received from an application executing on a client device, the device-agnostic request including a universal resource identifier (URI) for the video stream, the URI including a type of the video stream and at least one of a name of the video stream and device-specific parameters for the video stream. The URI is analyzed to identify a media device from which the video stream is available. A device-specific library for the media device is identified. A device-specific request corresponding to the device-agnostic request is executed to obtain the video stream, the device-specific request including the URI. The video stream is received from the media device responsive to executing the device-specific request. The video stream is provided to the application.
