Abstract
Systems, methods, and techniques for providing video forwarding in real-time video applications involving multiple devices. The techniques can be employed in WebRTC videoconferences, taking into account the heterogeneous natures of device display resolutions and networks in which the devices operate. The techniques employ a media server including an SFU having an adaptive video transcoder. The media server determines whether a benefit to QoE is achieved by performing video transcoding on large video streams produced by the respective devices. If a heterogeneity value of available network bandwidths is greater than a predetermined value and CPU/memory resources are available, then the adaptive video transcoder beneficially performs transcoding on the large video streams to produce corresponding small video streams, which are selectively forwarded to devices having low available network bandwidths. By providing an SFU with an adaptive video transcoder, improvements in the general QoE of devices in a videoconference can be achieved.
