摘要： Described is a technology by which code, such as an untrusted web application hosted in a browser, provides content through an interface for playback by an application environment, such as an application environment running in a browser plug-in. Content may be in the form of elementary video, audio and/or script streams. The content is in a container that is unpackaged by the application code, whereby the content may be packaged in any format that the application understands, and/or or come from any source from which the application can download the container. An application environment component such as a platform-level media element receives information from an application that informs the application environment that the application is to provide media stream data for playback. The application environment requests media stream data (e.g., samples) from the application, receives them as processed by the application, and provides the requested media stream data for playback.

摘要： Techniques enable locating a position within a file that corresponds to a desired seek time without having access to an index specifying the desired seek time's position. An iterative process may be used to estimate the position that corresponds to the desired seek time. The process may iterate through multiple estimations until a difference between a time corresponding to an estimated position and the desired seek time is within an acceptable amount or until the process reaches an iteration threshold. The file may then be played beginning at or near the desired seek time. The techniques may therefore allow a user to seek within a file while the user progressively downloads or streams the file.

摘要： Systems and methods for smooth rewind playback of streamed media are provided. The media includes relatively-encoded frames and independently-encoded frames. The method includes receiving a rewind request indicating a rewind speed for rewind playback of the media, selectively dropping relatively-encoded frame(s) based on a receipt constraint and a decoding constraint to form a subset of the media, and receiving frames of the subset. The method further includes selecting, in a reverse order, a selected group of pictures (GOP) included within the subset, and decoding relatively-encoded frame(s) of the GOP in a forward sequential frame order. The method further includes caching relatively-encoded frame(s) of the GOP in the forward sequential frame order, and when caching, dropping and overwriting relatively-encoded frame(s) of the GOP selectively according to a memory constraint and/or a display constraint. The method further includes displaying relatively-encoded frame(s) of the GOP in a reverse sequential frame order.

摘要： A method for video playback switching in response to changing network conditions. The method includes accessing a server to retrieve respective index files for a low bit rate version and a high bit rate version of the video file, and instantiating a low bit rate media player and a high bit rate media. Playback of the video file is begun by the high bit rate media player streaming the high bit rate version from the server. Upon an indication of impeded network conditions, a transition point is selected, wherein the transition point indicates where downloading of the high bit rate version stops and where downloading of the low bit rate version begins. The low bit rate media player is then positioned to begin playback at the transition point. Playback of the video file is then switched to the low bit rate player upon encountering the transition point.
