Platform general control method and system based on embedded linux audio player

Abstract

The invention discloses a platform general control method and system based on an embedded Linux audio player, wherein the method includes: based on the system business layer, acquiring user playback operation instructions; based on the player control interface layer docked with the system business layer , determine the local player call interface corresponding to the user’s play operation instruction, wherein the player control interface layer is configured with a plurality of local player call interfaces associated with the local player of the system hardware platform; based on the determined The local player calls the interface to call the local player on the system hardware platform to perform corresponding operations. Therefore, by setting the player control interface layer between the system business layer and the platform hardware player layer, the differences between different hardware platforms are shielded, and the interface technology is used to associate the local player with the business layer, without the need for business A large number of code modifications are made at the layer level, which greatly reduces the development pressure and shortens the product development cycle.

Description

technical field [0001] The invention belongs to the technical field of embedded Linux player applications, and in particular relates to a platform general control method and system based on an embedded Linux audio player. Background technique [0002] With the rapid development of computer technology and communication technology and the integration of 3C (computer, communication, consumer electronics), embedded systems have penetrated into various fields. With the penetration of embedded into various fields, especially with the development of intelligent voice, the popularity of a number of screenless embedded devices such as smart speakers and intelligent early education machines, the requirements for embedded Linux players are getting higher and higher. [0003] For embedded Linux players, not only are the requirements for performance and functions such as streaming media playback, multi-format support, and resampling higher and higher, but also the development cycle and i...

Problems solved by technology

[0005] However, the inventors of the present application found that the above-mentioned prior art has at least the following defects during the practice of the present application: the processing method only performs audio data stream processing based on user needs according to open source projects, or can only provide limited playback methods, As a result, it cannot meet the increasingly diversified playback needs

For example, when customers need to redesign the entire player process, they cannot quickly respond to customer customization needs. At the same time, when switching hardware platforms or switching systems, it will lead to a lot of repetitive work and waste of development resources.
