Abstract
Techniques are disclosed for video mixing in a distributed computing environment. For example, a method comprises the following steps. At a first mixing device, one or more local video streams are received from one or more sources local to the first mixing device. The first mixing device generates a first partially-composited video stream, wherein the first partially-composited video stream comprises: (i) a partial set of video elements of the one or more local video streams; and (ii) information about video elements of the one or more local video streams. The first mixing device sends the first partially-composited video stream to at least a second mixing device remote from the first mixing device. The first mixing device and the second mixing device may be part of a video conferencing system.
