FFmpeg开发笔记（六十二）Windows给FFmpeg集成H.266编码器vvenc
<span data-cke-copybin-start="1"><span data-cke-copybin-start="1">《</span></span>FFmpeg开发实战：从零基础到短视频上线》该书的第八章介绍了如何在Windows环境给FFmpeg集成H.264和H.265的编码器，如今H.266的编码器vvenc也日渐成熟，从7.1版本开始的最新FFmpeg源码已经支持H.266的编码器vvenc。<p> H.266是H.265的升级版本，H.265的视频编码标准为HEVC（High Efficiency Video Coding，高效视频编码），H.266的视频编码标准为VVC（Versatile Video Coding，多功能视频编码）。其中VVC是HEVC的后继者，目标是在相同视觉质量下将比特率降低50%。<br>
至于VVEnc（Versatile Video Encoder）是一个开源的高效视频编码器，它实现了最新的视频编码标准VVC，能够把视频数据按照H.266标准编码为VVC格式。VVEnc的源码托管地址为https://github.com/fraunhoferhhi/vvenc，国内的镜像地址为https://gitee.com/mirrors/vvenc。<br>
接下来以微软的视窗系统为例，介绍如何在Windows环境给FFmpeg集成H.266的编码器vvenc，具体的操作步骤说明如下：</p>
<h1>一、配置VVEnc</h1>
<p>先下载最新的vvenc源码，解压下载后的源码包，再打开cmake-gui程序（cmake-gui的安装说明见《FFmpeg开发实战：从零基础到短视频上线》第八章的“8.1.5 给FFmpeg集成x265”）。cmake-gui窗口界面的source code栏填vvenc的源码目录，where to build栏填vvenc源码下的build目录，接着单击窗口左下方的Configure按钮，配置完成的窗口界面如下图所示。</p>
<p><span class="cke_widget_wrapper cke_widget_inline cke_widget_image cke_image_nocaption cke_widget_selected" data-cke-display-name="图像" data-cke-filter="off" data-cke-widget-id="12" data-cke-widget-wrapper="1"><span class="cke_reset cke_widget_drag_handler_container"><span class="cke_image_resizer" title="点击并拖拽以改变尺寸"><span class="cke_widget_edit_container" title="编辑图片"><img src="https://img2024.cnblogs.com/blog/729938/202506/729938-20250602120911923-1490789672.png"></span></span></span></span></p>
<p>注意勾选窗口中间的BUILD_SHARED_LIBS选项，表示需要编译共享库也就是dll动态链接文件。然后单击窗口左下方的Generate按钮，生成完毕的窗口界面如下图所示。</p>
<p><span class="cke_widget_wrapper cke_widget_inline cke_widget_image cke_image_nocaption cke_widget_selected" data-cke-display-name="图像" data-cke-filter="off" data-cke-widget-id="11" data-cke-widget-wrapper="1"><span class="cke_reset cke_widget_drag_handler_container"><span class="cke_image_resizer" title="点击并拖拽以改变尺寸"><span class="cke_widget_edit_container" title="编辑图片"><img src="https://img2024.cnblogs.com/blog/729938/202506/729938-20250602120942648-1919068096.png"></span></span></span></span></p>
<p>接着单击窗口下方的Open Project按钮，让Visual Studio 2022打开已生成的vvenc工程。</p>
<h1>二、编译VVEnc</h1>
<p>Visual Studio 2022打开之后，依次选择顶部菜单：生成→配置管理器，在打开的配置管理器窗口上，找到左上角的“活动解决方案配置”下拉框，把Debug模式改为Release模式如下图所示，再单击窗口右下角的关闭按钮。</p>
<p><span class="cke_widget_wrapper cke_widget_inline cke_widget_image cke_image_nocaption cke_widget_selected" data-cke-display-name="图像" data-cke-filter="off" data-cke-widget-id="10" data-cke-widget-wrapper="1"><span class="cke_reset cke_widget_drag_handler_container"><span class="cke_image_resizer" title="点击并拖拽以改变尺寸"><span class="cke_widget_edit_container" title="编辑图片"><img src="https://img2024.cnblogs.com/blog/729938/202506/729938-20250602121019656-372912812.png"></span></span></span></span></p>
<p>依次选择顶部菜单：生成→生成→生成vvenc，Visual Studio就开始编译vvenc模块。编译过程可在Visual Studio界面下方观察，直到编译完成如下图所示。</p>
<p><span class="cke_widget_wrapper cke_widget_inline cke_widget_image cke_image_nocaption cke_widget_selected" data-cke-display-name="图像" data-cke-filter="off" data-cke-widget-id="9" data-cke-widget-wrapper="1"><span class="cke_reset cke_widget_drag_handler_container"><span class="cke_image_resizer" title="点击并拖拽以改变尺寸"><span class="cke_widget_edit_container" title="编辑图片"><img src="https://img2024.cnblogs.com/blog/729938/202506/729938-20250602121048269-991836996.png"></span></span></span></span></p>
<p>此时可在vvenc源码目录下找到bin和lib等目录，这些就是编译生成的可执行程序文件目录和库文件目录。</p>
<h1>三、安装VVEnc</h1>
<p>确保Windows系统已经按照《FFmpeg开发实战：从零基础到短视频上线》第一章“1.3 Windows系统安装FFmpeg”的说明安装配置了MSYS，再按照以下步骤在MSYS环境安装vvenc。<br>
1、在msys64的/usr/local目录下新建vvenc目录，并在该目录下创建lib子目录；<br>
2、把vvenc工程中lib\release-shared目录下的vvenc.lib和bin\release-shared目录下的vvenc.dll两个文件复制到第一步创建的lib目录；<br>
3、在lib目录下创建pkgconfig子目录，并把vvenc工程的build\pkgconfig\libvvenc.pc复制到pkgconfig目录；然后打开libvvenc.pc，把开头四行改成下面这样。</p>
<div class="cke_widget_wrapper cke_widget_block cke_widget_codeSnippet cke_widget_selected" data-cke-display-name="代码段" data-cke-filter="off" data-cke-widget-id="8" data-cke-widget-wrapper="1">

exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include</code></pre>
</div>
<p>4、把vvenc工程的include\vvenc目录复制到msys64的/usr/local/vvenc/include目录，把vvenc工程的build\vvenc目录也复制到msys64的/usr/local/vvenc/include目录；<br>
经过以上步骤操作后的vvenc目录结构如下所示。</p>
<div class="cke_widget_wrapper cke_widget_block cke_widget_codeSnippet cke_widget_selected" data-cke-display-name="代码段" data-cke-filter="off" data-cke-widget-id="7" data-cke-widget-wrapper="1">

<h1>四、编译安装FFmpeg</h1>
<p>先下载最新的FFmpeg源码（版本号需大于等于7.1），再把FFmpeg源码包复制到MSYS环境的/usr/local/src目录下。接着在MSYS控制台执行下面命令解压源码包：</p>
<div class="cke_widget_wrapper cke_widget_block cke_widget_codeSnippet cke_widget_selected" data-cke-display-name="代码段" data-cke-filter="off" data-cke-widget-id="6" data-cke-widget-wrapper="1">

</div>
<p>确保MSYS环境已经按照《FFmpeg开发实战：从零基础到短视频上线》该书第八章的“8.1.1 给FFmpeg集成x264”和“8.1.5 给FFmpeg集成x265”安装了H.264的编码器libx264和H.265的编码器libx265，也按照该书第十章的“10.1.1 FFmpeg集成SDL”安装了Windows系统的SDL2库，然后执行下面命令配置FFmpeg的编译环境：</p>
<div class="cke_widget_wrapper cke_widget_block cke_widget_codeSnippet cke_widget_selected" data-cke-display-name="代码段" data-cke-filter="off" data-cke-widget-id="5" data-cke-widget-wrapper="1">

</div>
<p>配置完毕执行下面命令编译和安装FFmpeg，编译完成的ffmpeg库将会安装到configure指定的/usr/local/ffmpeg目录。</p>
