Abstract
Systems and methods are described to enable synchronized encoding of streaming audio or video content between multiple encoders, in a manner that provides for seamlessly interchangeable encodings. Within a pool of encoders, each encoder can generate state information regarding its state of encoding, and share that state information with a controller. The control can compare the state information of the various encoders to determine whether a desynchronization has occurred. When a desynchronization does occur, such as due to intermittent network packet loss, the controller can determine an authoritative state for the pool, and instruct desynchronized encoders to resynchronize to the authoritative state, resulting in identical or interchangeable encoded content being output from each encoder of the pool.
