A computer-implemented method includes providing an online marketplace to developers of web applications that may be downloaded from the marketplace to a client computing device for execution by a browser executing on the client device and receiving a request from a party to the marketplace to list a proposed web application for sale in the marketplace. One or more processors of a computer system automatically determine the permissions requested by the proposed web application and automatically determine if the permissions match one or more predetermined permissions. If the permissions match one or more predetermined permissions, then the proposed application is flagged for a manual vetting process before listing the proposed application in the marketplace, and if they do not match, then the proposed application is listed in the marketplace without manual review of the application.

A computer implemented method enables presenting interesting and informative preview video of a video content item in a digital magazine. The method comprises steps of receiving a video content item from a content provider, e.g., a 2-minute video advertisement for a car from an advertiser, and analyzing the video content item. The video content item is segmented into multiple segments based on the analysis, e.g., scene changes detected with the video frames of the video content item. One or more segments are selected, e.g., based on their associated visual quality, and are combined to generate a preview video, e.g., a 10-second long video highlighting new features of the car. One or more transition segments can be added between segments to enhance user experience with the preview video. The preview video is provided to a client device for display and auto playback.

A system and method provide server side support for seamless, scalable rewind and playback of a video stream. A video stream is stored and indexed in a network storage place. A video stream can be indexed at frame level where each intra frame of the video stream has an index indicating the file offset and the time stamp of the intra frame in the video stream. A user request for rewinding of a video stream while the video stream is being broadcast is processed by extracting the rewinding time requirement from the user request. The extracted rewinding time value is used to calculate the requested file offset. The video stream starting at the requested time is retrieved and played back according to the user request. The system also provides server side support for seamless rewinding of a video stream and scalable system performance across multiple streaming data centers.
