Abstract

The invention relates to the technical field of network live broadcast and video coding, and provides a live video coding method based on prediction mode selection and computer equipment, and the method comprises the steps: obtaining a target reference block corresponding to each first coding block in a first live broadcast image in a first inter-frame prediction mode, judging whether the first coding block meets a preset mode selection condition or not; if yes, selecting a target prediction mode corresponding to the first coding block as a first inter-frame prediction mode; if not, obtaining rate distortion optimization information corresponding to the first coding block in each prediction mode, and obtaining a target prediction mode corresponding to the first coding block according to the rate distortion optimization information corresponding to the first coding block in each prediction mode; and obtaining a target prediction mode corresponding to the second coding block, and coding the coding blocks in the target prediction mode corresponding to each coding block to obtain a coded live video. Compared with the prior art, the encoding efficiency of the live video can be improved, and the live experience of the user is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of network live broadcasting and the technical field of video encoding, and in particular, to a live video encoding method and computer equipment based on prediction mode selection. Background technique [0002] With the rapid development of the live broadcast industry, more and more Internet platforms have begun to provide live broadcast services to attract users to interact with live broadcasts in live broadcast rooms. [0003] Live broadcast services include live video services and voice live services. During the live video service, the video content that users watch on the client is called live video, and the clarity and fluency of live video during playback will directly affect the user's live broadcast. experience. [0004] In the webcast scenario, the client can be divided into the host client and the audience client. After the host starts the webcast, it will trigger the ...
