Abstract

The invention discloses an audio and video screen projection method, device, equipment and system and a storage medium, and relates to the technical field of screen projection, and the method comprises the steps: obtaining audio and video data sent by terminal equipment; performing type analysis on the audio and video data based on a pre-stored type database to obtain a corresponding coding format; obtaining a target de-compounding plug-in according to the coding format and a pre-stored plug-in registry; creating an audio and video processing thread according to the target de-compounding plug-in; and performing de-compounding processing on the audio and video data based on the audio and video processing thread to obtain audio and video, and playing the audio and video. The problem that audio and video screen projection in the prior art is poor in compatibility is solved, and the technical effect that different terminal devices can be projected to the screen projection device is achieved.

Description

technical field [0001] The present invention relates to the technical field of screen projection, in particular to an audio and video screen projection method, device, equipment, system and storage medium. Background technique [0002] With the continuous development of network technology, people's requirements for smart products are getting higher and higher. Among them, TV is the main product of smart home, and mobile phones are the necessities of people's life. It is gradually important to connect mobile phones and TVs to realize screen projection. At present, TVs on the market have been loaded with many screen projection technologies, but there are still some problems in the compatibility of these screen projection technologies. Abnormalities such as no picture, this is because the TV cannot meet the audio and video formats of various mobile phone projection screens, resulting in poor compatibility. Contents of the invention [0003] The main purpose of the present in...
