Live video data coding bit rate adjusting method and apparatus

Abstract

An embodiment of the invention provides a live video data coding bit rate adjusting method and apparatus. The method comprises the following steps: an average coding bit rate and an average sending bit rate of the live video data are obtained at a preset period during direct broadcast of live video data; according to the average coding bit rate and the average sending bit rate, a network bandwidthscore can be calculated; according to the network bandwidth score, the coding bit rate of the live video data is adjusted; via application of the live video data coding bit rate adjusting method andapparatus, a network bandwidth environment can be learned about according to the network bandwidth score, the coding bit rate of the live video data can be adjusted in real time according to the network bandwidth environment, that live video data of a host can be smoothly sent to a streaming media server can be ensured, the host can interact with fans in real time, and user experience can be improved.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and device for adjusting the encoding bit rate of live video data. Background technique [0002] With the development of network technology, webcasting technology is becoming more and more mature. Webcasting can watch videos on different communication platforms through the network system at the same time. A webcasting usually faces tens of thousands, hundreds of thousands or even hundreds of thousands of people online. Tens of thousands of people, and communicate and interact with online audiences in real time. [0003] The maturity of webcast technology has led to the live broadcast of the show. The live broadcast of the show is hosted by the anchor. The anchor needs to broadcast live, and must be equipped with a high-definition camera, sound card, monitoring earphones, microphones, etc. The host compresses and encodes the audio or video signal and transmits it to the...

Problems solved by technology

[0004] However, due to unstable factors in the network, such as unreasonable uplink bandwidth allocation of operators, peak bandwidth usage and other factors, the anchor may encounter network congestion during the live broadcast process. On the anchor side, the audio and video After the data is compressed and encoded, there will be delays or even packet loss in the process of transmitting to the streaming media server. When the fans of the anchor watch on the client, the screen will stagnate or even jump, and they cannot watch the live broadcast of the anchor normally and smoothly. Video, as well as real-time interaction with the anchor, degrades the user experience
