Problems solved by technology

[0004] When a terminal sends a video update command to the MCU, the MCU will forward the video update command to the broadcast source terminal, so that the broadcast source terminal encodes I frames for the terminal, and the broadcast source terminal frequently encodes I frames, resulting in receiving this video Frequent image blurring or jitter occurs at the terminal of the code stream, which affects the user's video experience
And if the terminal sending the video update command has the same video capability as other terminals in the conference, the frequent encoding of I frames will also cause the terminal with the same video capability to appear blurry after receiving the video code stream

Abstract

The invention provides a video conference I frame coding method, which comprises the following steps of: determining a terminal of which the frequency of sending a video updating command is greater than a preset threshold value, if the terminal is judged not to meet a preset condition, coding an I frame according to a reserved VPU (Virtual Private Unit) resource, and sending the I frame to the terminal, namely, adopting an I frame optimization strategy; according to the method, the terminals with decoding errors are isolated, and targeted coding is carried out, so that other terminals participating in the conference are not influenced, the problem that all conference places are influenced due to packet loss of partial terminals in the video conference is solved, and the video transmission quality of the video conference is improved. The invention further provides an I-frame coding device, computer equipment and a computer readable medium.

Description

technical field [0001] The present disclosure relates to the technical field of video conferencing, and in particular to a video conference I-frame encoding method and device. Background technique [0002] With the rapid development of IP (Internet Protocol, Internet Protocol address) network and multimedia communication technology, video conferencing systems have been widely used in modern enterprises. The video conferencing system refers to the use of television equipment and video conferencing terminals to convene multiple terminals distributed in various places into the same conference through an MCU (Multipoint Control Unit, multipoint control unit). [0003] In practical applications, there are more and more small conferences and self-service conferences, and the network is becoming more and more complex, and some video conference systems are still running on the Internet. In a traditional video conferencing system, generally multiple terminals watch the broadcast sou...
