  • Patent number: 9973562
    Abstract: Techniques are described for split processing of streaming segments in which processing operations are split between a source component and a decoder component. For example, the source component can perform operations for receiving a streaming segment, demultiplexing the streaming segment to separate a video content bit stream, scanning the video content bit stream to find a location at which decoding can begin (e.g., scanning up to a first decodable I-picture, for which header parameter sets are available for decoding), and send the video content bit stream to the decoder component beginning at the location (e.g., the first decodable I-picture). The decoder component can begin decoding at the identified location (e.g., the first decodable I-picture). The decoder component can also discard subsequent pictures that reference a reference picture not present in the video content bit stream (e.g., when decoding starts with a new streaming segment).

  • Patent number: 9924200
    Abstract: An adaptive video noise reduction (AVNR) engine reduces noise in streaming video. The engine reads embedded information in the streaming video describing attributes of the video, such as bit rate, frame rate, resolution, content type and quality of the streaming video. The information may be included in a manifest of the streaming video. Based on the video attributes, the engine outputs one or more input values to applications that reduce noise of the streaming video. The one or more applications may reduce mosquito, block, temporal, random and banding noise of the video in response to the input values from the engine.

  • Publication number: 20170220283
    Abstract: Techniques and systems for reducing memory usage by a decoder during a format change are disclosed. In a first example technique, discretized memory allocations for new output buffers are sequenced with discretized release operations of previously-allocated memory for previous output buffers in a manner that reduces the amount of in-use memory of a computing device during a format change. In a second example technique, the allocation of new memory for new decoder buffers associated with a new format is conditioned upon the release of previously-allocated memory for decoder buffers associated with a previous format to reduce memory usage during a format change. The first and second techniques, when combined, result in optimized reduction in memory usage by a decoder during a format change.

  • Publication number: 20160360285
    Abstract: A system for video playback switching in response to changing network conditions. The system includes streaming, from a distribution device such as a server, respective index files for a low bit rate version and a high bit rate version of the video file, to remotely executing instantiations of 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 receiving and playing 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. The stream of the video file is then switched to the low bit rate player upon encountering the transition point.

  • Publication number: 20160277768
    Abstract: Disclosed herein are innovations in decoding compressed video media data. The disclosed innovations facilitate decoding operations with improved computational efficiency, faster speeds, reduced power, reduced memory usage, and/or reduced latency. In one embodiment, for example, an encoded bitstream of video media data is input from an external video content provider, the encoded bitstream being encoded according to a video codec standard. A decoder is then configured to decode the encoded bitstream based at least in part on supplemental information that identifies a property of the encoded bitstream but that is supplemental to the encoded bitstream (e.g., supplemental information that is not part of the encoded bitstream or its associated media container and that is specific (or related) to the application for which the bitstream is used and/or the standard by which the bitstream is encoded and/or encrypted).

  • Patent number: 9060190
    Abstract: 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.

  • Publication number: 20140337433
    Abstract: 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.
