Systems, methods, and storage media for updating media stream metadata in a manifest corresponding a media stream package

1. A system configured for updating metadata in a static manifest corresponding to a media stream package, the media stream package containing a sequence of media segments of a recorded media stream, the static manifest containing information describing the media segments in accordance with a predetermined specification and including a location of the corresponding video data files, the system comprising:

one or more hardware processors configured by machine-readable instructions to:

receive an original manifest corresponding to the media stream and a revised manifest corresponding to an updated version of the media stream, the revised manifest including metadata related to a new track to be added to the media stream to create the updated version of the media stream, wherein the new track is one of an audio track or a subtitle track;

determine a unique identifier of the track of the media stream based on a combination of metadata in the original manifest;

determine a unique identifier of a corresponding track of the updated version of the media stream based on a combination of metadata in the revised manifest;

determine new metadata in the revised manifest that is not included in the existing manifest based on the unique identifiers;

generate a delta manifest of the new metadata by comparing the original manifest and the revised manifest; and

insert the new metadata into the corresponding portions of original manifest and storing the resulting data structure to a data store associated with stored media objects for the updated to thereby generate a final manifest to be used for the media stream package.

2. The system of claim 1 , wherein the unique identifiers are generated based properties of a corresponding track.

3. The system of claim 2 , wherein the unique identifiers are generated in a manner that corresponds to the predetermined specification.

4. A method for updating metadata in a static manifest corresponding to a media stream package, the media stream package containing a sequence of media segments of a recorded media stream, the static manifest containing information describing the media segments in accordance with a predetermined specification and including a location of the corresponding video data files, the method comprising:

receiving an original manifest corresponding to the media stream and a revised manifest corresponding to an updated version of the media stream, the revised manifest including metadata related to a new track to be added to the media stream to create the updated version of the media stream, wherein the new track is one of an audio track or a subtitle track;

determining a unique identifier of the track of the media stream based on a combination of metadata in the original manifest;

determining a unique identifier of a corresponding track of the updated version of the media stream based on a combination of metadata in the revised manifest;

determining new metadata in the revised manifest that is not included in the existing manifest based on the unique identifiers;

generating a delta manifest of the new metadata by comparing the original manifest and the revised manifest;

inserting the new metadata into the corresponding portions of original manifest and storing the resulting data structure to a data store associated with stored media objects for the updated to thereby generate a final manifest to be used for the media stream package.

5. The method of claim 4 , wherein the unique identifiers are generated based properties of a corresponding track.

6. The method of claim 5 , wherein the unique identifiers are generated in a manner that corresponds to the predetermined specification.

7. A non-transient computer-readable storage medium having instructions embodied thereon, the instructions being executable by one or more processors to perform a method for updating metadata in a static manifest corresponding to a media stream package, the media stream package containing a sequence of media segments of a recorded media stream, the static manifest containing information describing the media segments in accordance with a predetermined specification and including a location of the corresponding video data files, the method comprising:

receiving an original manifest corresponding to the media stream and a revised manifest corresponding to an updated version of the media stream, the revised manifest including metadata related to a new track to be added to the media stream to create the updated version of the media stream, wherein the new track is one of an audio track or a subtitle track;

determining a unique identifier of the track of the media stream based on a combination of metadata in the original manifest;

determining a unique identifier of a corresponding track of the updated version of the media stream based on a combination of metadata in the revised manifest;

determining new metadata in the revised manifest that is not included in the existing manifest based on the unique identifiers;

generating a delta manifest of the new metadata by comparing the original manifest and the revised manifest;

inserting the new metadata into the corresponding portions of original manifest and storing the resulting data structure to a data store associated with stored media objects for the updated to thereby generate a final manifest to be used for the media stream package.

8. The computer-readable storage medium of claim 7 , wherein the unique identifiers are generated based properties of a corresponding track.

9. The computer-readable storage medium of claim 8 , wherein the unique identifiers are generated in a manner that corresponds to the predetermined.
