Abstract

A media feed is received and delineated into groups of pictures (GOPs) for processing into output media streams having different quality levels. The media feed needs only to be decoded once. The decoded stream is split along different paths based on resolution, and resized output media data is sent to multiple encoders and fragmenters to generate variants in bit rate and frame rate for each resolution. The generated variants may be maintained as fragments on shared storage. A particular stream corresponding to a particular variant can be reconstructed using the encoded fragments.
