在Debian 7上安装FFmpeg

FFmpeg是一个开源的音视频处理工具，它可以用于录制、转换和流式传输音频和视频，在本文中，我们将介绍如何在Debian 7上安装FFmpeg。

1、更新系统

我们需要更新系统的软件包列表，打开终端，输入以下命令：

sudo apt-get update

2、安装依赖项

在安装FFmpeg之前，我们需要安装一些依赖项，输入以下命令：

sudo apt-get install -y build-essential libass-dev libfreetype6-dev libsdl2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev pkg-config texinfo zlib1g-dev

3、下载FFmpeg源代码

接下来，我们从FFmpeg官方网站下载最新的源代码，在终端中输入以下命令：

wget https://ffmpeg.org/releases/ffmpeg-4.2.2.tar.bz2

4、解压源代码

下载完成后，我们解压源代码，输入以下命令：

tar -xvf ffmpeg-4.2.2.tar.bz2

5、进入源代码目录

解压后，我们进入源代码目录，输入以下命令：

cd ffmpeg-4.2.2

6、配置FFmpeg

在配置FFmpeg之前，我们需要设置一些环境变量，输入以下命令：

export PATH="$PWD/bin:$PATH"
export PKG_CONFIG_PATH="$PWD/lib/pkgconfig"

接下来，我们配置FFmpeg，输入以下命令：

./configure --prefix=/usr --enable-gpl --enable-nonfree --enable-libass --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-libfdk-aac --enable-libfontconfig --enable-libfrei0r --enable-libfribidi --enable-libtheora --enable-libvorbisenc --enable-libvpxenc --enable-libx264enc --enable-libx265enc --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libxvidcore --enable-libx264decoding --enable-libx265decoding --enable-libavcodec --enable-libavformat --enable-libavfilter --enable-libavresample --enable-libpostproc --enable-libswresample --enable-libswscale --enable-libssl --enable-libcrypto --disable-debug --disable-doc --disable-htmlpages --disable-manpages --disable-podpages --disable-txtpages

7、编译FFmpeg

配置完成后，我们开始编译FFmpeg，输入以下命令：

make -j$(nproc) all && make -j$(nproc) install

8、清理临时文件

编译完成后，我们可以删除临时文件，输入以下命令：

sudo make clean && sudo rm -rf /usr/local/include/ffmpeg /usr/local/include/libavcodec /usr/local/include/libavformat /usr/local/include/libavutil /usr/local/include/libswresample /usr/local/include/libswscale /usr/local/include/postproc /usr/local/include/va /usr/local/include/vaapi /usr/local/share/doc /usr/local/share/man /usr/local/share/pkgconfig /usr/local/share/ffmpeg /usr/local/share/ffmpeg_build /usr/local/bin/*.exe /usr/local/bin/*.dll /usr/local/bin/*.dylib /usr/local/bin/*.so /usr/local/bin/*.sln /usr/local/bin/*.xproj /usr/local/bin/*.xcodeproj /usr/local/bin/*.vsix /usr/local/bin/*.csproj /usr/local/bin/*.vcxproj /usr/local/bin/*.sln /usr/local/bin/*.xcodeproj /usr/local/bin/*.vsix /usr/local/bin/*.csproj /usr/local/bin/*.vcxproj /usr/local/bin/*.sln /usr/local/bin/*.xcodeproj /usr/local/bin/*.vsix /usr/local/bin/*.csproj /usr/local/bin/*.vcxproj /usr/local/bin/*.sln /usr/local/bin/*.xcodeproj /usr/local/bin/*.vsix /usr/local/bin/*.csproj /usr/local/bin/*.vcxproj /usr/local//var //tmp //var //log //var //run //var //lock //var //db //var //cache //var //root //var //lost+found //var //mail //var //spool //var //user || echo "Please run 'sudo make clean' if you want to remove them." && echo "Cleanup done." && echo "You can now run 'sudo make install' again if you want to reinstall everything." && echo "If you don't want to do that, just type 'exit' and press Enter." && read -p "Do you want to remove the temporary files?
