Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0027] In order to better understand the video bit rate adjustment method provided by the embodiment of the present invention, the basic architecture and process of the video cloud platform will be described first below. see figure 1 , not only shows the basic architecture and flow of live video on the video cloud platform, but also shows the basic architecture and flow of on-demand video on the video cloud platform. Such as figure 1 The basic structure and process of the live video on the video cloud platform are shown: 1. The host collects, quantifies, encodes and encapsulates the video stream data through the live terminal, and then uploads it to the live upload access module of the video cloud platform. The live broadcast terminal is a terminal equipped with audio equipm...

Abstract

The invention discloses a video code rate adjustment method and device, a server and a storage medium, and the method comprises the steps: obtaining state data used for indicating the performance of a network channel between a content distribution server and a client in the process of sending first video stream data to the client; if the state data satisfies the video code rate adjustment condition, obtaining a target I frame based on the I frame in the first video stream data sent to the client; based on the target I frame and the first code rate of the first video stream data, obtaining second video stream data, and sending the second video stream data to the client, wherein the header coding and decoding information and the timestamp information of the second video stream data are the same as those of the first video stream data, and the playing time point corresponding to the first I frame in the second video stream data is consistent with that corresponding to the target I frame. According to the embodiment of the invention, the video code rate can be automatically adjusted, and the video code rate adjustment efficiency is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a video code rate adjustment method, device, server and storage medium. Background technique [0002] At present, when the client starts to play the video stream, it will select a video bit rate by default. Generally, the original bit rate of the video stream is selected by default, or an appropriate video bit rate is selected based on the initial network loading situation of the client. If there is a playback freeze problem when the client is playing the video stream, the user usually needs to manually select a new video bit rate lower than the current video bit rate, so that the video stream can be played smoothly by switching to a low video bit rate. [0003] In the process of selecting a new video bit rate by the user, the user often needs to go through multiple attempts to select a suitable video bit rate. Multiple manual selections take a long time and are...
