FFmpeg开发笔记（七十三）Windows给FFmpeg集成MPEG-5视频编解码器
<span data-cke-copybin-start="1"><span data-cke-copybin-start="1"></span></span><span id="cke_bm_852S">MPEG-5是新一代的国际音视频编解码标准，像我们熟悉的MP3、MP4等音视频格式就来自于MPEG系列。MP3格式的说明介绍参见《FFmpeg开发实战：从零基础到短视频上线》一书的“5.2 MP3音频”，MP4格式的说明介绍参见《FFmpeg开发实战：从零基础到短视频上线》一书的“2.1.2 音视频文件的封装格式”。</span><p><span id="cke_bm_852S"> MPEG-5现已开源MPEG-5 EVC的视频编解码器，其中视频解码器的开源库叫libxevd，视频编码器的开源库叫libxeve。如今EVC的编解码器libxevd和libxeve日渐成熟，从7.0版本开始的最新FFmpeg源码已经支持EVC的编解码器libxevd和libxeve。<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MPEG-5 EVC视频编解码器libxevd和libxeve，具体的操作步骤说明如下：</span></p>
<h1>一、配置libxevd</h1>
<p>libxevd是一款MPEG-5的EVC视频解码器。它的源码托管页面在https://github.com/mpeg5/xevd/，最新版本是2024年4月发布的xevd-0.5.0，该版本的源码包下载地址是https://codeload.github.com/mpeg5/xevd/tar.gz/refs/tags/v0.5.0。<br>
libxevd的配置步骤说明如下。<br>
1、下载最新的xevd源码，再把xevd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="18" data-cke-widget-wrapper="1">
<pre class="cke_widget_element" data-cke-widget-data="%7B%22code%22%3A%22tar%20zxvf%20xevd-0.5.0.tar.gz%5Cncd%20xevd-0.5.0%22%2C%22classes%22%3Anull%7D" data-cke-widget-keep-attr="0" data-cke-widget-upcasted="1" data-widget="codeSnippet"><code class="hljs">tar zxvf xevd-0.5.0.tar.gz
cd xevd-0.5.0</code></pre>
</div>
<p>2、在xevd目录下创建新文件version.txt，文件内容填入“v0.5.0”，表示解码器的版本为0.5.0。<br>
3、执行下面命令配置xevd：</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="17" data-cke-widget-wrapper="1">
<pre class="cke_widget_element" data-cke-widget-data="%7B%22code%22%3A%22mkdir%20build%5Cncd%20build%5Cncmake%20..%22%2C%22classes%22%3Anull%7D" data-cke-widget-keep-attr="0" data-cke-widget-upcasted="1" data-widget="codeSnippet"><code class="hljs">mkdir build
cd build
cmake ..</code></pre>
</div>
<p>配置完毕，会在build目录下找到XEVD.sln，这就是xevd的Visual Studio项目工程文件。</p>
<h1>二、编译libxevd</h1>
<p>在xevd工程的build目录下创建xevd.def，并往该文件填入以下内容（其中函数列表来自inc\xevd.h定义的函数）：</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="16" data-cke-widget-wrapper="1">
<pre class="cke_widget_element" data-cke-widget-data="%7B%22code%22%3A%22LIBRARY%20xevd%5CnEXPORTS%5Cn%C2%A0%20xevd_create%5Cn%C2%A0%20xevd_delete%5Cn%C2%A0%20xevd_decode%5Cn%C2%A0%20xevd_pull%5Cn%C2%A0%20xevd_config%5Cn%C2%A0%20xevd_info%22%2C%22classes%22%3Anull%7D" data-cke-widget-keep-attr="0" data-cke-widget-upcasted="1" data-widget="codeSnippet"><code class="hljs">LIBRARY xevd
EXPORTS
xevd_create
xevd_delete
xevd_decode
xevd_pull
xevd_config
xevd_info</code></pre>
</div>
<p>打开Visual Studio 2022，在欢迎页面单击右侧的“打开项目或解决方案”，在弹出的文件对话框中选择xevd-0.5.0\build目录下的XEVD.sln。<br>
打开xevd工程后，右击解决方案管理器的xevd_dynamic模块，右键菜单依次选择：属性→配置属性→链接器→输入，在窗口右侧的模块定义文件栏填写xevd.def的绝对路径。继续依次选择：配置属性→链接器→高级，在窗口右侧的导入库栏填写待生成xevd.lib的绝对路径。完成设置后，单击右下角的确定按钮，保存xevd.def和xevd.lib的路径配置。<br>
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，再单击窗口右下角的关闭按钮。<br>
依次选择顶部菜单：生成→生成→生成xevd_dynamic，Visual Studio就开始编译xevd_dynamic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="15" 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/729938/202507/729938-20250712124543104-170910566.png"></span></span></span></span></p>
<p>此时可在xevd-0.5.0\build\src_main\Release目录下找到xevd.lib和xevd.dll，这两个文件就是编译生成的libxevd库文件。</p>
<h1>三、安装libxevd</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libxevd。<br>
1、在msys64的/usr/local目录下新建libxevd目录，并在该目录下创建lib子目录；<br>
2、把xevd工程中build\src_main\Release目录下的xevd.lib和xevd.dll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xevd工程的build\xevd.pc复制到pkgconfig目录；然后打开xevd.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="14" data-cke-widget-wrapper="1">

exec_prefix=${prefix}/bin
libdir=${prefix}/lib
includedir=${prefix}/include</code></pre>
</div>
<p>4、在msys64的/usr/local/libxevd目录下创建include目录，然后把xevd工程中inc\xevd.h和build\xevd_exports.h复制到刚才创建的include目录；<br>
经过以上步骤操作后的libxevd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="13" data-cke-widget-wrapper="1">

<h1>四、配置libxeve</h1>
<p>libxeve是一款MPEG-5的EVC视频编码器。它的源码托管页面在https://github.com/mpeg5/xeve/，最新版本是2024年6月发布的xeve-0.5.1，该版本的源码包下载地址是https://codeload.github.com/mpeg5/xeve/tar.gz/refs/tags/v0.5.1。<br>
注意：由于FFmpeg仅支持版本号大于等于0.5.1的libxeve，因此务必下载xeve-0.5.1，不可下载xeve-0.5.0。<br>
libxeve的配置步骤说明如下。<br>
1、下载最新的xeve源码，再把xeve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="12" data-cke-widget-wrapper="1">

cd xeve-0.5.1</code></pre>
</div>
<p>2、在xeve目录下创建新文件version.txt，文件内容填入“v0.5.1”，表示编码器的版本为0.5.1。<br>
3、执行下面命令配置xeve：</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="11" data-cke-widget-wrapper="1">

<p>根据以上返回的版本信息，可知已安装的FFmpeg版本号为7.1.1，同时configuration这行找到“--enable-libxevd --enable-libxeve”，说明FFmpeg已经启用了MPEG-5 EVC视频编解码器libxevd和libxeve。</p>
