Problems solved by technology
[0004] However, this increases the pressure on the encoding performance of the client, especially in the conference scene where the client may have multiple video uplinks and downlinks, and the requirements for the performance of the client codec are a big challenge
At the same time, different clients use different encoding hardware, and not all encoding hardware supports SVC encoding. Therefore, the universality of video communication methods provided by related technologies needs to be improved.

The invention relates to the technical field of video processing, and particularly provides a video communication implementation method and device, and a computer storage medium and electronic equipment for implementing the method. The method comprises the following steps: determining a first network congestion level of each video downlink party according to network bandwidths of the video downlink parties; updating the reference frame list according to the sequence value of the to-be-coded frame and the level of the to-be-coded frame in response to the existence of the first network congestion level greater than the preset value; performing scalable encoding according to the updated reference frame list to obtain an encoded video; and performing video communication between the video uplink party and each video downlink party based on the encoded video. According to the scheme, the pressure of the coding performance of a client or a server for SVC coding can be effectively reduced, anSVC coding scheme which does not depend on a hardware encoder supporting SVC coding is also provided, and thus a video communication scheme with relatively high universality is provided.
Description
technical field [0001] The present disclosure relates to the technical field of video processing, and in particular, to a method and device for realizing video communication, as well as a computer storage medium and electronic equipment for realizing the above method. Background technique [0002] With the rapid development of technology and communication infrastructure, video communication has greatly facilitated the life and work of users. In the process of video communication involving multiple parties, the video data will be compressed and transmitted to each video downlink party for decoding and viewing by the downlink party. For example, in a real-time video conference involving multiple parties, there may be a large difference in downlink bandwidth. If a video downlink end has a network anomaly, it will affect the normal viewing of videos on all video downlink ends, resulting in the inability to accommodate most users' video conferences. The question of effect. [0...
