Live media streams are encoded and fragmented to generate encoded fragments appropriate for different devices and networks. Different encoded fragments may correspond to different resolutions, audio bit rates, quality levels, and even codecs, etc. Devices request encoded fragments as needed to reconstitute a live media stream for playback. In many instances, encoding and fragmentation jobs are provided to numerous distributed and scalable encoder and fragmenter systems. Encoding and fragmentation jobs are intelligently weighted and scheduled to prevent any disruption or delay in playback of any particular live stream.
