Abstract

The invention provides a multilayer video transmission peak value removing method and system in a cloud conference and a storage medium, and the method comprises the steps: carrying out the initialization of a multilayer video, carrying out the reasonable control of each layer of coding frame according to a set code rate and an initialization wrong frame parameter of each layer, uniformly staggering an IDR frame with the maximum data size in each layer of video, and meanwhile, by adopting a method of dynamically adjusting a frame staggering interval, reducing and eliminating the possibility of code rate peak value occurrence at a multi-layer video coding end under the conditions of not reducing video quality, not increasing video delay and not reducing video continuity, so that the interaction with back-end transmission is simplified, a transmission layer flow control algorithm is combined, stable transmission of multi-layer video streams is realized, and the reliability of wide area internet video communication and the user experience are improved.

Description

technical field [0001] The present invention relates to the technical field of video transmission, in particular to a method, system and storage medium for peak removal of multi-layer video transmission in cloud conferences. Background technique [0002] As the demand for video conferencing becomes more popular and diversified, the solution has also evolved from traditional video conferencing to the current cloud video conferencing. In order to support multiple devices at the same time and ensure the maximum quality on different devices, there is a need for multi-layer video. For multi-layer video synchronization, multi-layer video will be sent at the same time, and transmitted in wireless channels such as WIFI, 4G / 5G, satellite, etc., and the bit rate peak will affect the video quality, so it is necessary to reduce and remove the bit rate peak in multi-layer video transmission. [0003] Currently, there are roughly two rate control schemes. One solution is to control the ...
