Methods and devices are described for generating a recipe for creating a clip. A clip request may be received at a server, such as a content server. The clip request may be related to a clip including audio and/or video. The server may include one or more processors and a cache, the cache including chunks. Each chunk may store a predetermined positive number of bytes of data. The server may search the cache to determine whether the clip is to be generated from a recipe stored within the cache. The recipe may include one or more tasks. The server may generate the clip in view of the one or more tasks of the recipe. The server may transmit a clip response comprising the clip to the client device.

Apparatus and methods for generating clips using recipes with slice definitions

Methods and devices are described for generating a recipe for creating a clip. A recipe request can be received at a server, such as a recipe server. The recipe request may be related to a clip including audio and/or video. The server can generate a recipe for creating the clip using one or more slices of a data source. The recipe can include one or more tasks that can include a data-source task which can include a specification of the data source and slice definitions for the one or more slices. The data source can include a video and/or audio data source. A slice definition can include a slice value and a slice offset for locating a respective slice within the data source. The recipe can then be transmitted from the server.

Injection of 3D metadata into a requested video is disclosed. An input video and associated metadata are received by a video hosting site. If the metadata indicates that the input video is a 3D video, the 3D video system extracts the accompanying 3D metadata and stores it in an intermediate format, which is independent of the 3D metadata format and video format of the input video. The 3D video system stores the received video in a standard 2D video format in a video database. Responsive to a video streaming request of the input video, the 3D video system determines the actual 3D metadata format based on the video format of the requested video, and injects a modified 3D metadata associated with the input video into the requested video.

Streaming-time 3D metadata injection

Apparatus and devices are described for generating clips by executing one or more tasks contained in a recipe. The recipe can be received at a server, such as a content server, perhaps as part of a clip request. The server can generate a clip by parsing the recipe. Parsing the recipe can include determining whether a given task of the one or more tasks is a data-source task and, in response to determining that the given task is a data-source task, extracting one or more slices of data from a data source specified in the data-source task and adding the one or more slices to the clip. The data source can include a video data source or a combined video and audio data source. Once generated, the clip can be sent from the server.
