An encoding system that distributes a live stream to end user devices is provided herein. The encoding system automatically detects failed components and implements a failover action to replace the failed component with a backup component in a manner that reduces live stream interruptions. For example, the encoding system can include a network interface that is coupled to an encoder allocated to a live stream. Instead of providing a contribution encoder that transmits the live stream with a location of the allocated encoder, the encoding system can provide the contribution encoder with a location of the network interface. Thus, the contribution encoder can transmit the live stream to the network interface. The network interface can then forward the live stream to the allocated encoder. If the allocated encoder fails, then the network interface can forward the live stream to a backup encoder.

Live media encoding failover system

An apparatus comprising a method for allocating shared processing resources, comprising the steps of (A) predicting a first amount of processing resources needed to complete each of a plurality of transcoding jobs in a work queue of a project, (B) determining a second amount of processing resources available prior to processing the project and (C) adding processing resources needed to complete the project. The processing resources are added in a fixed number of predetermined processing units. The fixed number of computer resources are added (a) to minimize an overall use of said processing resources needed to complete the project and (b) to complete the project within a target time.

Smart autoscaling of a cluster for processing a work queue in a distributed system

An apparatus includes a non-volatile storage medium and a processing circuit. The non-volatile storage medium stores code implementing an application program. The processing circuit may be configured to load and execute the code implementing the application program. At least a portion of the code implementing the application program is modified by the processing circuit to inject random errors in responses to requests from at least one calling program while an original definition of a functionality of the modified portion of the code implementing the application program remains unaltered. A particular random error injected is determined in response to configuration information received from a user.
