Managing encoder updates
A video packaging and origination service can include one or more encoder components that receive content for encoding and transmitting to requesting entities. During the operation of the encoder components, a management service associated with the video packaging and origination service can receive information related to updates or modifications to the encoder components. Responsive to the information, the management service can instantiate and configure an updated encoder. Once the updated encoder component is instantiated and configured, both the updated and target encoder components receive content for streaming, encode content and generating encoding content. Additionally, the updated encoder component can initiate a notification to the target encoder component that a handover will be occurring and begin a negotiation process identifying a handover event. Based on the negotiated handover event, the target encoder component can illustratively cease operation upon evaluation and detection of the handover event.
