Abstract
Provided is a method for processing video calls. The method includes: determining a layer bit rate corresponding to each frame layer in video data sent by a transmitter, wherein a plurality of video frames in the video data are organized into a plurality of frame layers based on an inter-frame dependency relationship, and the layer bit rate comprises a bit rate acquired by counting bit rates of video frames in a corresponding frame layer; determining, based on uplink bit rates corresponding to a plurality of receivers and a total downlink detected bandwidth, downlink allocated bandwidths corresponding to the receivers; determining, based on the downlink allocated bandwidths corresponding to the receivers and the layer bit rates, target frame layers corresponding to the receivers; and forwarding video data subjected to frame extraction processing for the target frame layers to corresponding receivers.
