Abstract
The present invention concerns a method for generating media files from video sequences, the method comprising by a server: obtaining from the video sequences, video data composed of a plurality of samples; generating a video track based on the obtained video data, each video track comprises samples of a video sequence, and the video track is associated with descriptive metadata, the descriptive metadata comprises: a spatial information related to one or more samples of the associated video track; and a composition information for organizing generated video tracks to get a full picture when displayed by a client; and generating media files including the generated video tracks.
Claims10
A method for generating media files from a video sequence, the method comprising:
- dividing the video sequence into multiple pieces;
- generating multiple video tracks to store the divided video sequence, each video track being associated with descriptive metadata, the descriptive metadata comprising:
- spatial information indicating that the video sequence is divided into multiple pieces, and
- a flag indicating that a track of the multiple video tracks is not intended to be presented alone;
- and
- generating the media files including the generated multiple video tracks along with the descriptive metadata.
A method for parsing media files comprising video data corresponding to a video sequence, the video data being composed of a plurality of samples, the method comprising:
- obtaining video tracks, each of the video tracks comprising samples of a piece of the video sequence, and said each of the video tracks being associated with descriptive metadata, the descriptive metadata comprising:
- spatial information indicating that the video sequence is divided into multiple pieces, and
- a flag indicating that a track of the multiple video tracks is not intended to be presented alone.
A device for generating media files from a video sequence, the device comprising a processor configured for:
- dividing the video sequence into multiple pieces
- generating multiple video tracks to store the divided video sequence, each video track being associated with descriptive metadata, the descriptive metadata comprising:
- spatial information indicating that the video sequence is divided into multiple pieces, and
- a flag indicating that a track of the multiple video tracks is not intended to be presented alone;
- and
- generating the media files including the generated multiple video tracks along with the descriptive metadata.
