摘要： This is directed to systems, methods and computer-readable media for media files having timed and untimed location metadata. For example, a media file can include timed location metadata stored in a metadata track of the media file, such that individual timed packets of location information are each associated with different portions of the recorded media. In some embodiments, the location metadata can include information describing the direction the device is facing and/or elevation/tilt of the device relative a horizontal plane (e.g. a plane perpendicular to a line between the device position and the center of the earth) and/or a motion of the device.

摘要： The operation of a video playback application supporting display of an encoded video may be validated using a special-purpose video decoder. The decoder compares pre-determined indications of dependency frames for frames of the video with dependency frames that are identified based on an order in which the frames are provided to the decoder. Based on the comparison, the decoder verifies that the frames may be decoded with correct dependencies. In one implementation, a frame of a video is accessed. A first description and a second description identifying frames of the video upon which decoding of the accessed frame depends are accessed. The first description is compared to the second description, and whether the first and second descriptions identify a common set of frames is determined based on the identifying.

摘要： A sequence of video images can be represented using multiple related timelines by generating a first timeline identifying a decode order associated with a sequence of video images and a second timeline identifying a display order associated with the sequence of video images, wherein the sequence of video images is comprised of one or more samples. The first and second timelines can be correlated based on an offset, which represents a time period by which decoding precedes display. The sequence of video images can then be played in accordance with the correlated first and second timelines. Additionally, the decode order in the first timeline can differ from the display order in the second timeline. A revised offset between the first and second timelines can be determined after the sequence of video images has been edited and the first and second timelines can be correlated based on the revised offset.

摘要： Methods, systems and machine readable storage medium for allowing playback of streaming media at playback rates of other than 1× are described. In one embodiment, a method can determine different sets of I-frames that are available before a display deadline, where each set can have a different cadence, and one of the sets can be selected for download and display to achieve playback at other than 1×. Byte range requests from a client device can be used to retrieve each of the I-frames. Other methods, system and media are also described.

摘要： Buffers may be shared between components in a system. The components may be loosely coupled, allowing the components to be assembled into various different configurations, and yet buffers may still be shared. A buffer requirements negotiator of the system analyzes the buffer requirements of each of the components and determines, if possible, a set of requirements that satisfies all of the components. Accordingly, savings may be achieved in buffer memory, as well as in copying and converting between unshared buffers. Further, the individual components may operate as efficiently as possible because the buffer requirements of the components in the system are all met. One implementation accesses a first component's buffer requirements and a second component's buffer requirements, determines a reconciled set of buffer requirements that satisfies the buffer requirements of both components, and provides the reconciled set of buffer requirements to one or more components.

摘要： A method is provided through which information about media files embedded in web pages is obtained from a server and analyzed to determine if the media files are playable on a device. This information may be external to the media file or may be a portion of the media file itself. The determination of whether a media file is playable by a device is made based on information obtained from the server without downloading the entirety of the media file.

摘要： Systems, methods, devices that enable the efficient synchronization of timing information from first time-based process to a second time-based process using periodic or event-driven synchronization messages are provided. In one aspect, the invention includes a media processing system having a first process for processing media based, at least in part, on first timing information derived from a first timing source and a second timing source. The system may also include a second process for processing the media based, at least in part, on second timing information derived from the first timing source. The first process may send one or more timing synchronization messages, generated based at least in part on the first timing source and the second timing source, to the second process to synchronize the second timing information with the first timing information.
