Publication number: 20230247239Abstract: A method for streaming an audio-video file can include: receiving a request for a playback segment of the audio-video file in a rendition from a computational device; in response to identifying absence of the playback segment in the rendition from a rendition cache and identifying absence of an assignment to transcode the playback segment in the rendition: assigning a worker to transcode the playback segment in the rendition. The method can also include, at the worker: identifying a subset of mezzanine segments in the set of mezzanine segments coinciding with a playback interval in the audio-video file; and for each mezzanine segment in the subset of mezzanine segments: concurrently transcoding the mezzanine segment into a rendition segment in the rendition and transmitting the rendition segment coinciding with the playback interval to the computational device via a peer-to-peer stream; and storing the rendition segment in the rendition cache.Type: ApplicationFiled: April 6, 2023Publication date: August 3, 2023Inventors: Jon Dahl, Adam Brown, Nick Chadwick, Matt Ward, Scott Kidder
