Description
Technical field
The present invention relates to Android system technical field of data processing, is specifically a kind of using method of communication encoding and decoding assembly of Android system.
Background technology
The media stream engine of having researched and developed can be reception, send media stream provides processing, comprises that audio/video catches, encodes, decodes, plays up.Carry multiple encoding and decoding, and can carry out third party's encoding and decoding expansion.Media engine has multiple cross-platform versions, can operate in android platform, and user can experience video communication function by it.
But this media engine generally adopts software codec, because software codec relies on the disposal ability of cpu completely, real-time Transmission and can produce while processing audio frequency and video and seize, hang dead problem, causes efficiency lower.
Summary of the invention
For the defect existing in prior art, the object of the present invention is to provide a kind of using method of communication encoding and decoding assembly of Android system, utilize hardware compression device, thereby promote encoding-decoding efficiency, bring better user to experience with this.
For reaching above object, the technical scheme that the present invention takes is: a kind of using method of communication encoding and decoding assembly of Android system, based on the hardware compression device of OpenMax integrated layer and OpenMax development layer, comprise the following steps: step S1. writes the assembly client of assembly and the OpenMax integrated layer of OpenMax integrated layer, described assembly client can be called described assembly, and then by the hardware compression device of assembly client call OpenMax development layer; Step S2. creates Streaming Media hardware compression plug-in unit, and the interface of described assembly client is encapsulated; The information of described hardware compression device is write configuration file by step S3., upper layer application, by configuration file, is selected Streaming Media hardware compression plug-in unit, calls the interface of described assembly client, and then call the interface of described assembly, finally call described hardware compression device.
On the basis of technique scheme, described Streaming Media hardware compression plug-in unit is Streaming Media engine filter.
On the basis of technique scheme, described assembly comprises audio-frequency assembly, video component and image component.
On the basis of technique scheme, described assembly has the function of encoding and decoding processing; Described assembly client completes assembly function by calling described assembly.
On the basis of technique scheme, described configuration file also comprises the information of software codec.
On the basis of technique scheme, the concrete steps of step S2 are: step S201. creates Streaming Media hardware compression plug-in unit; The interface of described assembly client is pressed the encapsulation of Streaming Media Plugin Requirement by step S202.; Step S203. uses the interface of Streaming Media hardware compression plug-in unit, calls the interface of the assembly client after encapsulation, completes initialization, processing and the cleaning of described hardware compression device.
Beneficial effect of the present invention is:
1, the present invention utilizes hardware compression device, because hardware compression device disposal ability is stronger than software codec, can use exclusive device or parts (as GPU etc.), has therefore promoted encoding-decoding efficiency, has brought better user to experience.
2, to utilize the OpenMax development layer of hardware compression adaptation and OpenMax integrated layer be standard interface in the present invention, can carry out easily the expansion of hardware compression device.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Shown in Figure 1, OpenMAX is the standard of a multimedia application, comprises three layers, is respectively application layer, integrated layer and development layer.In OpenMax integrated layer, important part is assembly (component), and assembly is the core content that OpenMax integrated layer is realized, and an assembly is taking input, output port as interface, and port can be connected on another assembly.Outside can send order to assembly, also arrange/get parms, the content such as configuration.The port of assembly can comprise the queue of buffering area (Buffer).In Android system, OpenMax integrated layer, can be for the plug-in unit of media engine, and the media engine OpenCore of android and StageFright can use OpenMax as plug-in unit, is mainly used in encoding and decoding (Codec) and processes.
Shown in Figure 2, the embodiment of the present invention provides a kind of using method of communication encoding and decoding assembly of Android system, based on the hardware compression device of OpenMax integrated layer and OpenMax development layer, comprises the following steps:
Step S1. writes the assembly client of assembly and the OpenMax integrated layer of OpenMax integrated layer, and described assembly client can be called described assembly, and then by the hardware compression device of assembly client call OpenMax development layer; Described assembly comprises audio-frequency assembly, video component and image component.Described assembly, has the function of encoding and decoding processing; Described assembly client, completes assembly function by calling described assembly.
Step S2. creates Streaming Media hardware compression plug-in unit, and the interface of described assembly client is encapsulated; Described Streaming Media hardware compression plug-in unit is Streaming Media engine filter.
The concrete steps of step S2 comprise:
Step S201. creates Streaming Media hardware compression plug-in unit.
The interface of described assembly client is pressed the encapsulation of Streaming Media Plugin Requirement by step S202..
Step S203. uses the interface of Streaming Media hardware compression plug-in unit, calls the interface of the assembly client after encapsulation, completes initialization, processing and the cleaning of described hardware compression device.
The information of described hardware compression device is write configuration file by step S3., shown in Figure 3, and upper layer application is passed through configuration file, select Streaming Media hardware compression plug-in unit, call the interface of described assembly client, and then call the interface of described assembly, finally call described hardware compression device.Configuration file stores is at application program place file, for routine call.Described configuration file also comprises the information of software codec.
