Abstract: Implementations for combining at least two video streams received from devices of a plurality of participants of a video conference into a composite video stream are described. A video conference including the video streams received from the devices of the plurality of participants is established. A capability associated with consuming at least two of the video streams is received from at least one of the devices. The at least two video streams are then combined into a composite video stream based on the capability associated with consuming the at least two video streams. The composite video stream is transmitted to the at least one of the devices.

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: Implementations for combining a plurality of content based on instructions for a layout of a video conference are described. A video conference is established between a plurality of devices of participants of the video conference. First content is received from a device of the plurality of devices in the established video conference. Second content is also received. Instructions for a layout of the first content and the second content during the video conference is received. Based on the instructions for the layout, the first content and the second content are combined into a composite video stream. The composite video stream is saved or transmitted.
