Problems solved by technology

However, when the network channel itself is already congested, the SR / RR packets that come and go once in a while may also be lost. As long as the SR / RR packets lack one of them, the effective packet loss rate information cannot be obtained, resulting in code The rate cannot be adjusted in time

Abstract

The invention discloses a method for adjusting a video code rate. The method comprises the following steps of: counting a packet loss rate and a received video code rate according to packet header information of a received real-time transmission protocol packet; generating an information packet according to the packet loss rate and the received video code rate; sending the information packet, wherein a receiving end obtains the packet loss rate and the video code rate of the sending end according to the information packet, and the video code rate of the receiving end is adjusted according to the packet loss rate and the video code rate of the sending end. According to the method disclosed in the invention, accurate and rapid adaptive adjustment of the video code rate in the communication process can be realized. The embodiment of the invention further discloses a video code rate adjusting system, a terminal and a storage medium.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method, system, terminal and storage medium for adjusting a video code rate. Background technique [0002] In the field of network communication, the general network video communication system will use UDP (User Datagram Protocol) to send RTP (Realtime Transport Protocol) / RTCP (Realtime Transport Control Protocol) packets for data transmission and instructions in order to ensure the real-time effectiveness of video images. control. However, since UDP transmission does not have a channel congestion detection and elimination mechanism, when the network is unstable and causes congestion, packet loss will occur, which will eventually cause problems such as stuttering, mosaic, and picture delay when the receiving end decodes. [0003] In the prior art, in order to solve this phenomenon, the video communication system will regularly send SR / RR packets in RTCP p...
