Problems solved by technology

[0004] However, because the network conditions used to transmit compressed video streams fluctuate every moment, and the compressed video streams are pre-generated based on the previous feedback from the network, the estimated network capacity has a lag. Continuous time, it is difficult to adjust the video quality in real time, which may cause picture freezing and loss during real-time video

Abstract

The invention discloses a video frame transmission method, a video frame transmission system and a server, and the method comprises the steps: enabling a sending end to obtain original video data andreference network information fed back by a receiving end; determining a first code rate and a second code rate according to the reference network information; encoding a to-be-transmitted video framein the original video data according to the first code rate and the second code rate respectively to obtain a first video frame corresponding to the first code rate and a second video frame corresponding to the second code rate; obtaining current network information, and matching the first video frame, the second video frame and the current network information to obtain a matching result; and sending the first video frame or sending the second video frame or not sending the video frame to a receiving end according to the matching result. According to the technical scheme provided by the invention, the video fluency and stability are improved.

Description

Technical field [0001] The present invention relates to the field of Internet technology, in particular to a video frame transmission method, system and server. Background technique [0002] With the rapid development of the Internet, real-time video technologies such as video conferencing, cloud video games, robots and vehicle remote control are constantly improving. [0003] In the current real-time video transmission system, the sender can use the transmission protocol to estimate the average data transmission rate in the network path, and provide the estimated value to the codec, and the codec determines the coding parameters based on the estimated value, for example , Bit rate, etc., and generate a compressed video stream according to the determined encoding parameters, so that the average bit rate of the generated compressed video stream is close to the estimated network capacity, and the produced compressed video stream is sent to the receiving end using the transmission pro...
