Abstract: A spectating system that generates game inputs based on spectator inputs and interactions, and provides the game inputs to game systems according to an application programming interface (API). The spectating system may allow spectators to interact with and affect a game being broadcast via inputs to and interactions with user interface (UI) elements presented on the spectating UI. Spectators may affect or influence the game, objects within the game universe, events within the game, or the players in the game via the UI elements on the spectating UI. The spectators may become involved in the games being broadcast by influencing game play via the spectating inputs. Game play for the players may be enhanced by providing interesting variations in game play based on the spectating inputs.

Abstract: A virtual world generation engine and methods for generating virtual worlds from images collected from various sources, including crowdsourced images. A virtual world generation engine may obtain images (e.g., digital photographs, digital video frames, etc.) related to a particular real-world scene, combine the images using image processing techniques such as image stitching techniques to generate composite images representing a view of the scene, and generate models from the composite images. The models may be used in rendering video content representing virtual worlds generated from the collected images of real-world scenes; the video content may be streamed to client device(s). Obtaining the images, generating models, rendering video content from the models, and streaming the video content may be performed in response to user interactions with video content on the client device(s) to allow interactive exploration of the virtual worlds in real-time or near-real time.

Abstract: A real-time video exploration (RVE) system that allows users to pause, step into, move through, and explore 2D or 3D modeled worlds of scenes in a video. The RVE system may allow users to discover, select, explore, and manipulate objects within the modeled worlds used to generate video content. The RVE system may implement methods that allow users to view and explore in more detail the features, components, and/or accessories of selected objects that are being manipulated and explored. The RVE system may also implement methods that allow users to interact with interfaces of selected objects or interfaces of components of selected objects.

Abstract: A real-time video exploration (RVE) system that allows users to pause, step into, and explore 2D or 3D modeled worlds of scenes in a video. The system may leverage network-based computation resources to render and stream new video content from the models to clients with low latency. A user may pause a video, step into a scene, and interactively change viewing positions and angles in the model to move through or explore the scene. The user may resume playback of the recorded video when done exploring the scene. Thus, rather than just viewing a pre-rendered scene in a movie from a pre-determined perspective, a user may step into and explore the scene from different angles, and may wander around the scene at will within the scope of the model to discover parts of the scene that are not visible in the original video.

Abstract: Disclosed are various embodiments for developing versions of applications based on application fingerprinting. For example, an application may be ported from one operating system platform to another, or an application may be modified to be compatible with a specific device. In one embodiment, an application fingerprint is received for an application. The application fingerprint may be generated based at least in part on a static analysis of the application and a dynamic analysis of the application. A device that is incompatible with the application based at least in part on the application fingerprint may be determined. A modification to the application to make the application compatible with the device may be determined.
