一、xvid、x264、ffmpeg源码下载

二、安装

1. xvid

1. tar zxvf xvidcore-1.3.3.tar.gz
2. cd xvidcore/build/generic
3. ./configure --prefix=/usr/local/soft_install --enable-shared --enable-pic
4. make -j 8
5. make install

2. x264

1. tar jxvf last_x264.tar.bz2
2. cd x264-snapshot-20161225-2245
3. ./configure --prefix=/usr/local/soft_install --enable-shared --enable-pic --disable-asm
4. make -j 8
5. make install

3. ffmpeg

1. 安装依赖包
   sudo apt-get install libfaac-dev libmp3lame-dev libtheora-dev libvorbis-dev libxvidcore-dev libxext-dev libxfixes-dev

2. ./configure --prefix=/usr/local/soft_install/ffmpeg --enable-gpl --enable-version3 --enable-nonfree --enable-postproc --enable-pthreads --enable-libfaac --enable-libmp3lame --enable-libtheora --enable-libx264 --enable-libxvid --enable-x11grab --enable-libvorbis

出现错误:

Unknown option "--enable-libfaac".
See ./configure --help for available options.

原因是新版ffmpeg已经remove了 libaac

又出现异常信息

nasm/yasm not found or too old. Use --disable-x86asm for a crippled build.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

添加–disable-x86asm 编译成功

./configure --prefix=/usr/local/soft_install/ffmpeg --enable-gpl --enable-version3 --enable-nonfree --enable-postproc --enable-pthreads --enable-libmp3lame --enable-libtheora --enable-libx264 --enable-libxvid --enable-libvorbis --disable-x86asm

三、修改环境变量

1. vi /etc/profile
   在文件末尾添加

# ffmpeg
export PKG_CONFIG_PATH=/usr/local/soft_install/ffmpeg/lib/pkgconfig:$PKG_CONFIG_PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/soft_install/ffmpeg/lib
export PATH=$PATH:/usr/local/soft_install/ffmpeg/lib:/usr/local/soft_install/ffmpeg/bin

1. source /etc/profile

2. 成功标志
