A timeline source is described. In an implementation, a method includes examining a plurality of nodes within a media timeline, where at least two of the nodes reference respective media. The media timeline is for exposure over an API. The media timeline is divided into one or more presentations. Each presentation describes rendering of the media for a particular interval of time.

Systems and methods for resolving a partial topology are disclosed. In one embodiment a media engine includes a topology loader module that receives a partial topology from another module associated with the media engine. The topology loader implements logic operations that convert a partial topology into a full topology, which may be returned to the media engine for presentation of the media stream(s) to a user.

Methods and systems for processing media content are described and in at least some embodiments utilize a composite or composition, which can be considered as a representation of an editing project as a single track. Editing projects can have one or more tracks, and each track can be associated with one or more data stream sources that can have effects or transitions applied on them. Compositions can be nested inside one another and provide an economical way for complex editing manipulations to take place.

A software enabled, matrix switch is presented wherein a scalable plurality of inputs, coupled to media content sources, provide media content which is recursively routed through select media processing object(s) coupled to a scalable plurality of matrix switch outputs in accordance with a user-defined media processing project.

Methods and systems for managing multiple inputs that are capable of competing or contending for a particular or primary output are described. In one embodiment, the multiple inputs are managed through the use of a software-implemented matrix switch object, and an associated data structure that is used to program the switch object and resolve contention issues between the inputs. The matrix switch object can process the multiple inputs to provide a primary output. One implementation of the switch object uses virtual input and output pins to receive and provide data streams. One specific embodiment is used in connection with multi-media editing software that enables users build or define their own editing multi-media editing projects that incorporate multiple different user-selected clips, in the form of digital data streams, into an integrated project. Each clip can be defined in terms of one or more digital data streams, e.g. video and audio streams. One implementation method defines a first data structure that represents an editing project and processes the data structure to provide a second data structure that contains data that can be used to program the matrix switch object so that multiple switch inputs are routed to multiple switch outputs and contentions between the inputs for a primary output are resolved.

A system receives an indication to generate a filter graph representing a user-defined development project. Media sources that are to be used in the user-defined development project are identified and a programming grid is establishing that incorporates a user's editing instructions. A matrix switch filter is generated based, at least in part, on the programming grid. The filter graph is assembled and comprises a plurality of individual filters. Buffer size and attribute characteristics are negotiated between an input/output of the matrix switch filter and an input/output of adjacent filters. Negotiated buffers are utilized to communicate media content between the matrix switch filter and adjacent filters by sharing a common buffer between inputs and outputs.

In one embodiment, a network-bound request for a multi-media file is intercepted to determine whether the file is located locally on a user computer. If the file is located on the user computer, it is retrieved. If the file is unavailable locally, the file is retrieved from a network-accessible location. In another embodiment, a file locator is configured to intercept network-bound requests for multi-media files and determine whether the files are available locally using a list that includes local file directories where files may be stored. When a user retrieves a file from a network and saves it in a directory, if the list does not include the directory, the list is updated to include the directory. If the file locator cannot find the file locally, the user is prompted to select a directory where the file is stored, and the list updated to include the directory.
摘要:
A system is presented including a plurality of sources, and an interface, selectively coupled to the plurality of sources, to generate and implement a development project of processing chains, wherein the interface dynamically loads a processing chain for each of the plurality of media sources at a point during the execution of the project when the chain is required, and wherein the interface is configured to unload at least a subset of the chains when they are not required.
摘要:
Systems for processing multi-media editing projects are described. In one embodiment, a computing system comprises input means for generating a request for one or more multi-media files for use in a multi-media editing project, one or more processors, one or more computer-readable media having computer-readable instructions thereon which, when executed by the one or more processors, perform a method comprising: intercepting the request; ascertaining whether a requested multi-media file is located on the user computer by checking one or more user-designated directories for the multi-media file; retrieving the multi-media file if the file is located on the user computer; and seeking the requested file from the network-accessible location if the multi-media file is not located on the user computer.
