Abstract: A video packaging and origination service can include one or more encoder components that receive content for encoding and transmitting to requesting entities. Responsive to a request for content, an encoder can determine an initial set of parameters based on network measurements, including buffer size, bitrate and output resolution. Once the updated encoder component is instantiated and configured, the encoder can monitor performance and dynamically modify keyframe interval and framerate parameters to allow for streaming in lower bandwidth networks.

Abstract: Described are systems and methods for providing a publisher-subscriber architecture for audio and/or video conferencing. Embodiments of the present disclosure can utilize one edge computing resource associated with each client device participating in the audio and/or video conference. One or more client devices can publish streams to the associated edge computing resources. The streams can then be pushed, via a data network, to the edge computing resources associated with the subscribing client devices. The subscribing client devices can access and fetch the streams from the edge computing resources, which can be presented on the client devices as part of a conferencing session experience.

Abstract: Techniques for migrating live broadcast streams from one data center to another data center are described herein. A data center from a plurality of data centers may be determined to transfer live streaming video content from a first data center to the data center. A separate live streaming session for each live streaming session being broadcast by the first data center may be generated by communicating with an ingest service server that receives media content used to generate each separate live streaming session and the live streaming session. Each separate live streaming session may be routed to the candidate data center. A determination that each separate live streaming session of the candidate data center is synchronized with each live streaming session of the first data center may be made. An update to a mapping of IP addresses to redirect requests from the first data center to the candidate data center.
