Design Of Stream Analysis Based On AVS2 Encoder

As multimedia information develops dramatically fast,video services application were widely applied in numous fields such as network multicast,highquality digital video etc.,and it comes the new launched generation of video code standard AVS2 in China.it is a clear imperative to have a technical AVS2 stream analysis software to help network video operators and professional video producers and other engineers and technicians to exploit new products and business rapidly and make economical gain.Moreover,traditional decoder stream analyzer is simply the deduction of encoding mode,which is unable to realize real time analysis,and can not reach the suboptimal results,all these will make it a difficult to horizontally understand the video code process,however,the stream analysis in the encoder solves all above issues,and help video technicians to reach out more about code process and pursue the most optimal result suitable for certain conditions.As a consequence,it is indeed significant and urgent to launch a stream analysis based on AVS2 encoder.Thesis based on AVS2 code standard,it designed by Microsoft software MFC class libraries,and realizes the graph and digital display of most important parameters in the code process.The design fits main software and source code together in the encoder,saves intermediate parameters in the process.The software entrance is available to input parameters,achieve different video code process,realize the real time display of stream in the encoder in video playing areas and accomplish the play,pause,forward and retreat function on the screen.It realizes the minimum code unit devision in the fram of picture,continual devision of intraframe prediction block type,interfram prediction block type,prediction block in the SKIP and DIRECT.It will furthely digital display the optimal brightness prediction mode in the interframe code unit,show the reference motion direction of vectors in the intraframe code unit,achieve unit block devision under the final encoding method.It realizes the real time display of sequence headers,graphs and key information in code block of the clicked minimum code unit in the digital region.Finally thesis adds the intraframe code unit suboptimal mode and optimal mode in contrast,stresses the advantages of stream analysis in the encoder.
