A method of providing edited media content is described. The method comprises: generating captured content and a representation of the captured content, the representation of the captured content having a smaller size than the captured content; providing the captured content over a first network path across a network and the representation of the captured content over a second network path across the network, the first network path having a higher latency than the second network path; generating an edited version of the received representation of the captured content; and providing an edited version of the captured content, the editing of the captured content being based on the editing of the representation of the captured content.

A MSS chunking method for an MP4 file, an MSS adapter, and a non-transitory computer-readable storage medium are disclosed. The method may include: receiving an MSS download request for downloading of at least one MSS chunk of a first MP4 file; determining, according to MSS chunk indexes and virtual chunk indexes of the first MP4 file, data segments in the first MP4 file corresponding to data of the at least one MSS chunk, each MSS chunk index containing a playing address of a respective MSS chunk of the first MP4 file, and each virtual chunk index containing a correspondence between the data of a respective MSS chunk and a respective one of data segments of the first MP4 file; sending a data segment download request to a media server and receiving data segments; and assembling contents of the data segments to generate the at least one MSS chunk.

A method, apparatus and computer program product are provided to store and signal pre-derivation properties in an image container file (24, 26). Relative to the construction of image package comprising an image container file, the method, apparatus and computer program product assign a pre-derivation property identifier data structure identifying one or more pre-derivation properties of one or more pre-derived images (22). With respect to the processing of an image container file, the method, apparatus and computer program product permit an image container file and a pre-derivation property identifier data structure identifying one or more pre-derivation properties of one or more pre-derived images in the image be processed to cause one or more pre-derived image items from the image container file to be rendered or edited and regenerated in accordance with the pre-derivation properties.

In various examples, a media stream may be received by a re-encode system that may leverage a recode engine to convert (e.g., at an interval, based on a request, etc.) an inter-frame associated with the media stream to an intra-frame. The intra-frame may be converted from the inter-frame using parameters or other information associated with and received with the media stream. The converted intra-frame may be merged into an updated segment of the media stream in place of the original inter-frame to enable storage of the updated segment—or a portion thereof—for later use.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for validating and publishing workflows from remote environments. In some implementations, a link that includes at least one of audio data and video data is established between a wireless device of a remote participant and a computational mixer. A profile for the remote participant is referenced. A venue signal related to the at least one audio data and video data is generated based on the profile for the remote participant and using the computational mixer. The venue signal is transmitted.

Systems and methods for adaptively streaming video content to a wireless transmit/receive unit (WTRU) or wired transmit/receive unit may include obtaining a media presentation description that comprises a content authenticity, requesting a key for a hash-based message authentication code; receiving the key for the hash-based message authentication code, determining a determined hash for a segment of the media presentation description, requesting a reference hash for the segment from a server, receiving the reference hash for the segment from the server, and comparing the reference hash to the determined hash to determine whether the requested hash matches the determined hash.

In one aspect, an example method includes (i) receiving a first group of video content items; (ii) identifying from among the first group of video content items, a second group of video content items having a threshold extent of similarity with each other; (iii) determining a quality score for each video content item of the second group; (iv) identifying from among the second group of video content items, a third group of video content items each having a quality score that exceeds a quality score threshold; and (v) based on the identifying of the third group, transmitting at least a portion of at least one video content item of the identified third group to a digital video-effect (DVE) system, wherein the system is configured for using the at least the portion of the at least one video content item of the identified third group to generate a video content item.

The disclosure provides a video synthesis method, a terminal and a storage medium. The method includes acquiring at least one video clip. The method includes acquiring a target audio suitable to video content based on the video content and the number of the at least one video clip. T number of the audio change points of the target audio is greater than or equal to the number of at least one video clip minus one, and the audio change points comprise time points at which change in audio feature satisfies a preset condition; and obtaining a video file by synthesizing the at least one video clip and the target audio based on the audio change points included in the target audio.
