Description: （利用GIF_LZW算法实现的）网络图片传输 技术特点 ~~~~~~~~ 一、使用TCP协议传输数据。理由：稳定性好。 二、使用字节数据流进行传输，理由： A:VB的String存在自动Unicode转换问题，影响速度； B:可以直接发送8位字节数据，不需要使用Base64编码，从而减少了编码时间。 三、使用GIF-LZW压缩算法压缩图像。理由： A:行程编码、Huffman压缩算法压缩率太低； B:JPEG压缩算法需要太多位运算，且运算量大（有专门MMX优化算法），不利于VB实现； C:GIF-LZW压缩算法压缩率较好，且我已想出VB语法下高效GIF-LZW压缩/解压算法。 四、使用“有序抖动”算法进行 色彩量化。理由：“有序抖动”处理的结果具有一定规律性，有助于LZW类算法压缩。-(using GIF_LZW algorithm) picture transmission network ~~~~~~~~ a technical features, the use of TCP to transmit data. Reason : good stability. Two, the use of byte data stream for transmission, reasons : A : VB String exist automatically Unicode conversion, the impact speed; B : can directly send eight bytes of data and do not need to use Base64 encoding, thereby reducing the coding time. 3, the use of GIF- LZW compression algorithm for image compression. Reason : A : itinerary coding, Huffman compression algorithm compression rate is too low; B : JPEG compression algorithm needs much-bit computing, and large amount of computation (with MMX specialized optimization algorithm), is not conducive to VB; C : GIF- LZW compression algorithm compression ratio better, and I have come up with un Platform: |

Description: 《BASM for Beginners Lessons》本文档是SkyJacker翻译修订的BASM 初学者入门PDF版，内容中英文对照，原始英文版作者 Dennis Kjaer Christensen.这些文章通过函数实例来介绍 BASM。通常，这些函数首先使用 Pascal 编写，然后从 Delphi 编译器的 CPU 窗口中复制汇编代码，之后进行分析和优化。也包括使用 MMX, SSE 或 SSE2 指令的优化。-" BASM for Beginners Lessons" This document is a translation of the revised BASM beginners SkyJacker entry PDF version of the content in bilingual, the original English version by Dennis Kjaer Christensen. Examples of these articles through a function to introduce BASM. Typically, these functions to prepare the first to use Pascal and Delphi compiler from the CPU window, copy the assembly code, followed by analysis and optimization.

Description: 本解码库以ffmpeg为参考模型，针对不同档次的H.264码流进行了修正，解码核心部分进行了相应的MMX优化。
整个解码过程分3个步骤进行，只需要按顺序调用头文件里描述的初始化、处理、释放这三个函数即可。
解码得到的图像数据为YUV，该工程将YUV转换为RGB，直接显示，省去了解码后，还需要借助YUVViewer等工具打开YUV文件的步骤，更加的方便快捷。
支持各个档次的H.264码流解码，将H.264码流放在H264Test目录下即可。
编译平台：VC6.0,VC2005,VC2008.
-The decoding library to ffmpeg as a reference model for different grades of H.264 streams was amended to decode the core parts of the corresponding MMX optimization. The whole decoding process comprises three steps, according to the order simply call the header file describing the initialization, handling, release of these three functions can be. Decoded image data obtained as YUV, the project would convert YUV to RGB, direct display, eliminating the need for decoding, but also with tools such as open YUV file YUVViewer steps, more of the convenient. Support the various grades of H.264 stream decoding, the H.264 yards in exile in H264Test directory can be. Compile Platform: VC6.0, VC2005, VC2008. Platform: |
