Systems and methods for on-the-fly repackaging

A server system of a media-providing service, comprising:

• one or more processors;
• and
• memory storing one or more programs for execution by the one or more processors, the one or more programs comprising instructions for performing a set of operations, comprising:
• receiving a first media content item comprising a plurality of segments from a producer of the first media content item;
• receiving, from a second electronic device, a first request to initiate playback of the first media content item;
• and
• in response to receiving the first request:
• determining a first insertion time within the first media content item for inserting a second media content item, distinct from the first media content item, into the first media content item;
• generating a queue that indicates an order in which a first file, a second file that is distinct from the first file, and a third file that is distinct from each of the first file and the second file are to be provided, wherein:
• the first file corresponds to a first subset of the plurality of segments of the first media content item from a start of the first media content item until the first insertion time;
• the second file corresponds to the second media content item;
• and
• the third file corresponds to a second subset of the plurality of segments of the first media content item starting at the first insertion time, and includes information corresponding to a reference to a segment in the first subset of the plurality of segments;
• generating the first file and the third file in accordance with the queue without decoding the first media content item and without re-encoding the first subset of the plurality of segments or the second subset of the plurality of segments;
• and
• providing the first media content item and the second media content item to the second electronic device, including queuing the second electronic device to play back the first file, the second file, and the third file in accordance with the queue.

A non-transitory computer-readable storage medium storing one or more programs configured for execution by a computer system associated with a media-providing service, the one or more programs comprising instructions for performing a set of operations, comprising:

• receiving a first media content item comprising a plurality of segments from a producer of the first media content item;
• receiving, from a second electronic device, a first request to initiate playback of the first media content item;
• and
• in response to receiving the first request:
• determining a first insertion time within the first media content item for inserting a second media content item, distinct from the first media content item, into the first media content item;
• generating a queue that indicates an order in which a first file, a second file that is distinct from the first file, and a third file that is distinct from each of the first file and the second file are to be provided, wherein:
• the first file corresponds to a first subset of the plurality of segments of the first media content item from a start of the first media content item until the first insertion time;
• the second file corresponds to the second media content item;
• and
• the third file corresponds to a second subset of the plurality of segments of the first media content item starting at the first insertion time, and includes information corresponding to a reference to a segment in the first subset of the plurality of segments;
• generating the first file and the third file in accordance with the queue without decoding the first media content item and without re-encoding the first subset of the plurality of segments or the second subset of the plurality of segments;
• and
• providing the first media content item and the second media content item to the second electronic device, including queuing the second electronic device to play back the first file, the second file, and the third file in accordance with the queue.
