Problems solved by technology

[0003] However, the multimedia engine generally uses a software codec. Because the software codec completely relies on the processing power of the CPU, real-time transmission and processing of audio and video will cause problems such as preemption and hangup, resulting in low efficiency.

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0018] see figure 1 As shown, OpenMAX is a multimedia application standard, including three layers, namely application layer, integration layer and development layer. The important part of the OpenMax integration layer is the component. The component is the core content of the OpenMax integration layer. A component uses input and output ports as interfaces, and the ports can be connected to another component. External components can send commands, and also set / get parameters, configuration, etc. A component's port can contain a queue of buffers. In the android system, the OpenMax integration layer can be used as a plug-in for a multimedia engine, and both OpenCore and StageFright, an android multimedia engine, can use OpenMax as a plug-in, mainly for codec (Codec) processing.

Abstract

A use method of a communication coding-decoding assembly of an android system relates to the technical field of data processing technique of the android system. The use method comprises the following steps: a step S1, compiling an assembly of an OpenMax integrated layer and an assembly client of the OpenMax integrated layer, wherein the assembly client can call an assembly, and furthermore a hardware coder-decoder of an OpenMax developing layer is called through the assembly client; a step S2, creating a flow media hardware coding-decoding plug-in and packaging an interface of the assembly client; and a step S3, writing the information of the hardware coder-decoder into a configuration file, selecting the flow media hardware coding-decoding plug-in by an upper-layer application through the configuration file, calling the interface of the assembly client and furthermore calling the interface of the assembly, and finally calling the hardware coder-decoder. According to the use method, the hardware coder-decoder is utilized, thereby improving coding efficiency and decoding efficiency, and therefore better user experience is realized.

Description

technical field [0001] The invention relates to the technical field of android system data processing, in particular to a method for using a communication codec component of the android system. Background technique [0002] The developed multimedia stream engine can provide processing for receiving and sending multimedia streams, including audio / video capture, encoding, decoding, and rendering. Comes with a variety of codecs, and can perform third-party codec extensions. The multimedia engine has multiple cross-platform versions, can run on the android platform, and users can experience video communication functions through it. [0003] But this multimedia engine generally adopts software codec, because software codec completely relies on the processing power of cpu, real-time transmission and processing audio and video can produce the problem of preemption, hang-up, resulting in low efficiency. Contents of the invention [0004] Aiming at the defects in the prior art, t...
