In the such scheme, described audio/video decoding storehouse comprises tool model, demultiplexing module, decoder module and picture Zoom module.
In the such scheme, tool model reaches reusing of source code for the modules in audio/video decoding storehouse provides general function interface; Demultiplexing module is unpacked to file or network data, therefrom extracts the Voice ﹠ Video data; Decoder module is exported the audio frequency and video initial data that the Android system supports to the Voice ﹠ Video decoding data.
In the such scheme, described dynamic base based on the C language is comprised of three parts: jni module, audio frequency output module and video output module.
In the such scheme, described JAR storehouse is comprised of two parts: java api module and jni api module.
In the such scheme, the described player method that flows player based on the general RTSP of Android system:
Step 1: each functional module of initialization;
Step 2: tool model obtains audio, video data;
Step 3: demultiplexing module is unpacked to the data of obtaining, and isolates the Voice ﹠ Video data;
Step 4: the decoding data of decoder module to separating, pass to dynamic base;
Step 5: dynamic base is play decoded audio, video data and is shown.
In the such scheme, the player method of player, at first call the java api module in the JAR storehouse when described each functional module of step 1 initialization, then described java api module is called the function in the jni api module, then by modules in the described dynamic base of jni method call.
In the such scheme, the player method of player, after described step 1 finished, the RTSP address passed to tool model in the audio/video decoding module by the jni method, after tool model obtains this address, carry out interactive authentication and data acquisition by socket and RTSP server.
In the such scheme, the player method of player, in described step 4, decoder module is to extract data format from the SDP domain information that streaming media server returns, and the parameter in described decoding storehouse is set.
In the such scheme, the player method of player, described audio/video decoding storehouse can be processed the floating-point in the ARM framework and multimedia instruction.
Compared with prior art, the beneficial effect of technique scheme: because the audio/video decoding storehouse and based on the dynamic base of C language at the C space motion, improved the decoding efficiency of audio frequency and video; Support the broadcast of the audio/video flow of RTSP agreement; Support the operating system of Android 2.0 and above version; Support ARMv6 framework and above ARM chip platform, therefore have versatility.

Fig. 2 is workflow diagram of the present invention.
Embodiment
As shown in Figure 1, based on the general RTSP stream player of Android system, comprise the audio/video decoding storehouse, based on the dynamic base of C language with based on the JAR storehouse of Java language.
The audio/video decoding storehouse is comprised of four parts: tool model, demultiplexing module, decoder module and picture Zoom module form.
Dynamic base based on the C language is comprised of three parts: jni module, audio frequency output module and video output module.
The JAR storehouse is comprised of two parts: java api module and jni api module.
The tool model in audio/video decoding storehouse reaches reusing of source code for the modules in audio/video decoding storehouse provides general function interface; Demultiplexing module is unpacked to file or network data, therefrom extracts the Voice ﹠ Video data; Decoder module is to the Voice ﹠ Video decoding data, thus the audio frequency and video initial data that output Android system supports.
, for providing the bridge of communication, JAR storehouse and audio/video decoding storehouse guarantee mutually to call between Java and the C language based on the jni module of the dynamic base of C language; The audio frequency output module is sent the voice data of exporting in the audio/video decoding storehouse into system bottom and is play; The video output module is sent the video data of exporting in the audio/video decoding storehouse into system bottom and is shown.
The java api module in JAR storehouse provides the api that can call function for the developer; Jni api module provides the JAR storehouse the inner api function that uses, and does not open to the outside world, can call power function in the dynamic base by jni api.
The workflow of the general RTSP stream player of the Android system that is based on that Fig. 2 shows, its workflow comprises initialization flow process and playing flow.
The initialization flow process:
Call the java api module in the JAR storehouse, then this module is called the function in the jni api module, then pass through the initial method of modules in the jni method call dynamic base, wherein when initialization jni module, can call the initial method of modules in the audio/video decoding storehouse, so far finish the initial work of all modules.
Playing flow:
At the java layer, the RTSP address passes to the audio/video decoding storehouse by the jni method, after tool model obtains this address, carries out interactive authentication and data acquisition by socket and RTSP server; Demultiplexing module is unpacked the data that tool model obtains, and isolates Voice ﹠ Video data wherein; Decoder module is respectively for the Voice ﹠ Video decoding data, then decoded data returned to audio frequency output module in the dynamic base and video output module and plays and show.
In order to allow player reach the effect of anticipation, technical scheme has overcome following difficulty:
1. in order to allow the correct compiling in audio/video decoding storehouse and true(-)running on Android system and ARM chip platform, made following modification:
A) the processor parameter in audio/video decoding storehouse is set, is appointed as the ARM framework;
B) the cross-platform compile option in audio/video decoding storehouse is set;
C) increase is to the support of the instructions such as floating-point, multimedia in the ARM framework.
2. in order to allow tool model correctly compile, made following modification:
Because the compilation tool of Android is not supported the restrict keyword, revise the config.h file under the source code of audio/video decoding storehouse, #define restrict restrict is revised as #define restrict; Revise the libavutil/libm.h file, static method is wherein all deleted;
3. in order to allow demultiplexing module correctly compile, and support file greater than 4GB, made following modification:
Revise the file_seek () function in the libavformat/file.c file, lseek () function is revised as lseek64 () function, make the demultiplexing module support greater than the file of 4GB;
4. for the data format of resolution flow media server, revise the libavformat/rtsp.c file.After the modification, send the SDP domain information that the rear streaming media server of Describe order returns with resolving, therefrom extract data format, thereby the parameter in decoding storehouse is set, make audio/video decoding have more autgmentability.
