摘要： A system for video compositing is comprised of a storage device for storing a composite timeline file. A timeline manager reads rendering instructions and compositing instructions from the stored file. A plurality of filter graphs, each receiving one of a plurality of video streams, renders frames therefrom in response to the rendering instructions. A uniform resource locator (URL) incorporator generates URL based content. Hardware is responsive to the rendered frames, URL based content, and compositing instructions for creating a composite image. A frame scheduler is responsive to the plurality of filter graphs for controlling a frequency at which the hardware creates a new composite image. An output is provided for displaying the composite image. Methods of generating a composite work and methods of generating the timeline file are also disclosed. Because of the rules governing abstracts, this Abstract should not be used to construe the claims.

摘要： Systems and methods are provided for generating a composite video based on a plurality of asynchronously recorded input video streams. A plurality of segments of the input video streams are identified. A number of the input video streams that were recording during the particular segment are determined. A video display configuration for the particular segment is determined based on the number of video streams that were recording, where the video display configuration includes a display sub-region for each of the number of video streams that was recording. A composite video is generated, where the composite video includes a portion of video associated with each of the segments, where the composite video portion associated with the particular segment is formatted according to the video display configuration and displays the video streams that were recording during the particular segment in the display sub-regions of the video display configuration.

摘要： Systems and methods are provided encoding a video. Video data is captured. The video data is stored in a group of pictures format, where the group of pictures format comprises a plurality of GOP files, each GOP file including exactly one group of pictures unit. The video data is encoded into a prespecified format. Encoding includes accessing the GOP files containing the video data in the group of pictures format, and encoding the video data into the prespecified format using the GOP files to generate an encoded video.
