Abstract

The invention provides a method for adjusting a video coding code rate according to a network condition. A video coding module A, a video data module B, a video data sending module C, a code rate adjusting module D and a packet loss rate calculation module E in a server are included. The invention aims to dynamically adjust the video code rate through system judgment, so that a terminal video picture can be automatically adjusted through a network condition. The mobile phone intelligent terminal is used as a video source; the shot picture is sent to the server; the server performs real-time detection and calculation; packet loss calculation is carried out on the data every three seconds; according to the method, the video code rate is dynamically adjusted through a software system, the process of manually adjusting the code rate is canceled, and the video call video effect is better and more intelligent. The method has the advantages that the video code rate can be dynamically adjustedthrough the software system, and the video call video effect is better and more intelligent.

Description

technical field [0001] The present invention relates to the technical field of video encoding processing, in particular to a method for adjusting video encoding rate according to network conditions. Background technique [0002] At present, there are more and more VoIP (Voice over Internet Protocol) applications. These applications can use the camera equipment of mobile smart terminal equipment to collect video data, and then use IP (Internet Protocol foreign language abbreviation) network, which transmits the real-time video screen of the smart terminal of the mobile phone to other terminals. [0003] Generally, we use the UDP transmission protocol (abbreviation for User Datagram Protocol, which provides transaction-oriented simple and unreliable information transmission services) for the real-time performance of video images. However, due to poor network conditions, there will be network jitter and network packet loss, which will cause blurred screen and freeze problems w...
