Encodingless Transmuxing

A device comprising:

• a non-transitory computer-readable medium storing a set of processor-executable instructions;
• and
• one or more processors configured to execute the set of processor-executable instructions, wherein executing the set of processor-executable instructions causes the one or more processors to:
• obtain a single file encoding media content, the single file comprising metadata and binary data, wherein the binary data stores frame information for a plurality of frames representing the media content, and wherein the plurality of frames comprises a set of key frames irregularly intermixed with other frame types;
• detect positions of first, second, and third key frames of the set of key frames from said metadata;
• transmux the single file into a plurality of segments based on a segment duration parameter by:
• commencing a first segment of the plurality of segments with the first key frame;
• determining that the third key frame is closer than the second key frame to a position that is the segment duration parameter from the first key frame in the media content, wherein the third key frame is at a different position in the media content than the position that is the segment duration parameter from the first key frame;
• commencing a second segment of the plurality of segments with the third key frame, wherein the second segment immediately follows said first segment during playback of the media content;
• serve the first segment in response to a user request for the first segment, wherein said serving comprises providing a subset of the binary data without encoding, decoding, or modifying two or more frames falling within the subset of the binary data, wherein the subset of the binary data commences at binary data encoding the first key frame, spans binary data encoding the second key frame and other frames between the first key frame and the third key frame, and ends with a frame immediately before binary data encoding the third key frame.

A non-transitory computer-readable medium, storing a set of processor-executable instructions, which, when executed by one or more processors, cause the one or more processors to:

• obtain a single file encoding media content, the single file comprising metadata and binary data, wherein the binary data stores frame information for a plurality of frames representing the media content, and wherein the plurality of frames comprises a set of key frames irregularly intermixed with other frame types;
• detect positions of first, second, and third key frames of the set of key frames from said metadata;
• transmux the single file into a plurality of segments based on a segment duration parameter by:
• commencing a first segment of the plurality of segments with the first key frame;
• determining that the third key frame is closer than the second key frame to a position that is the segment duration parameter from the first key frame in the media content, wherein the third key frame is at a different position in the media content than the position that is the segment duration parameter from the first key frame;
• commencing a second segment of the plurality of segments with the third key frame, wherein the second segment immediately follows said first segment during playback of the media content;
• serve the first segment in response to a user request for the first segment, wherein said serving comprises providing a subset of the binary data without encoding, decoding, or modifying two or more frames falling within the subset of the binary data, wherein the subset of the binary data commences at binary data encoding the first key frame, spans binary data encoding the second key frame and other frames between the first key frame and the third key frame, and ends with a frame immediately before binary data encoding the third key frame.
