Optimizing Caches For Media Streaming

In a digital medium environment to fragment digital content for efficient user access of the digital content, a method implemented by at least one computing device of a media source system, the method comprising:

• obtaining, by the at least one computing device, a media stream;
• obtaining, by the at least one computing device, time references, the time references corresponding to the obtained media stream;
• identifying, by the at least one computing device, key frames in the media stream, each of the identified key frames being a first key frame following a corresponding time reference from among the obtained time references;
• generating, by the at least one computing device, fragments of the media stream corresponding to at least a portion of the identified key frames, each of the generated fragments including an associated contiguous sequence of frames starting with the identified key frame;
• indexing, by the at least one computing device, the generated fragments in an index file according to an indexing protocol;
• and
• storing, by the at least one computing device, on storage media communicatively coupled with the at least one computing device, the index file and the generated fragments.

In a digital medium environment to fragment digital content for efficient user access of the digital content, a media source system comprising:

• a storage device;
• a processor;
• and
• memory, the memory comprising instructions that are executable by the processor to configure the media source system to:
• obtain a media stream;
• obtain time references, the time references corresponding to the obtained media stream;
• identify key frames in the media stream, each of the identified key frames being a first key frame following a corresponding time reference from among the obtained time references;
• generate fragments of the media stream corresponding to at least a portion of the identified key frames, each of the generated fragments including an associated contiguous sequence of frames starting with the identified key frame;
• index the generated fragments in an index file according to an indexing protocol;
• and
• store, on the storage device, the index file and the generated fragments.
