使用FFMPEG SDK解码流数据获得YUV数据及其大小

本文以H264视频流为例，讲解解码流数据的步骤。为突出重点，本文只专注于讨论解码视频流数据，不涉及其它（如开发环境的配置等）。如果您需要这方面的信息，请和我联系。准备变量定义AVCodecContext。如果您使用类，可以定义成类成员。我这里定义成全局变量。staticAVCodecContext*g_pCodecCtx=NULL;定义一个AVFrame，AVFrame描述一个多媒体帧。解码后的数据将被放在其中。staticAVFrame*g_pavfFr

厘清了xorg里的一些概念

作者:网络日期:2009-07-01http://www.linuxgraphics.cn/xwindow/some_concepts_of_xorg.html今天看到一篇不错的英文文章，解释了xorg实现里的一些概念，也解决了我的一些疑惑。概括并解释一下。期待已久的DRI2被排除出了Xorg7.4版本了，为什么呢？是为了给GEM取代TTM让路，而DRI2的实现目前依赖于TTM。目前的Xserver渲染架构严重落后于时代，自Xfree时代遗留的问题在Xor

JavaScript 的性能优化：加载和执行

概览无论当前JavaScript代码是内嵌还是在外链文件中，页面的下载和渲染都必须停下来等待脚本执行完成。JavaScript执行过程耗时越久，浏览器等待响应用户输入的时间就越长。浏览器在下载和执行脚本时出现阻塞的原因在于，脚本可能会改变页面或JavaScript的命名空间，它们对后面页面内容造成影响。一个典型的例子就是在页面中使用document.write()。例如清单1清单1JavaScript代码内嵌示例Sou</span>
