When preparing an application to connect to an Amazon Chime SDK meeting, you can enable simulcast in the MeetingSessionConfiguration object. With simulcast enabled, clients will upload multiple video streams from the same video source using different resolutions and bitrates up to 1280x720 and 1200 kbps. For clients displaying remote video tiles, the VideoAdaptiveProbePolicy chooses which stream to subscribe to factoring in downlink bandwidth, number of video streams shared in the meeting, and by prioritizing content share over webcam video streams.
The Amazon Chime SDK is a set of real-time communications components that developers can use to quickly add audio calling, video calling, and screen sharing capabilities to their own web or mobile applications. Developers can leverage the same communication infrastructure and services that power Amazon Chime, an online meetings service from AWS, and deliver engaging experiences in their applications.
