编译支持MP3,H264编码的ffmpeg

ffmpeg原有的系统中支持mp3和h264的解码，但是编码并不支持，所以，需要是应用第三方插件进行支持；

从configure --help可以看出：

点击(此处)折叠或打开

[StevenLiu@liudeMacBook-Pro ffmpeg]$ ./configure --help 
  --enable-libstagefright-h264 enable H.264 decoding via libstagefright [no]
  --enable-libx264 enable H.264 encoding via x264 [no]
 --enable-libmp3lame enable MP3 encoding via libmp3lame [no]

首先系统中需要包含libx264与libmp3lame，这两个lib能够从对应的git中下载得到

MP3编码对应web: http://lame.sourceforge.net/download.php

libx264对应Web: http://www.videolan.org/developers/x264.html

安装mp3编码库

点击(此处)折叠或打开

./configure
make
make install

安装libx264编码库

点击(此处)折叠或打开

./configure
make
make install

此处可以改为 ./configure --prefix=/usr/local/x264

以修改安装目录，之后在 /etc/profile 中加入 export PATH="/usr/local/x264/bin:$PATH"

再运行 source /etc/profile

把x264的路径加入到系统变量里

可以用命令 which x264 测试一下

x264, FFmpeg 的安装都需要yasm支持，当安装的过程中遇到需要yasm的时候，可以--disabled-yasm，当然，并不建议disabled调，还是安装yasm更好一些

x264需要最新的yasm支持，apt安装的不可用，所以要去官网 http://yasm.tortall.net/Download.html 下载安装

如果需要支持h264与mp3的话，可以使用如下参数进行支持

./configure --enable-libmp3lame --enable-libx264 --enable-gpl

由于libx264的code有GPL信息，所以，支持libx264时，需要--enable-gpl，ffmpeg在license方面还是比我们国内的人更重视

然后make&&make install即编译安装ffmpeg

接下来可以试一下

ok，生成完毕

我使用的配置是

./configure --enable-memalign-hack --enable-ffserver --enable-network --enable-protocols --enable-muxers --disable-yasm --enable-shared --enable-w32threads --enable-libx264 --enable-gpl --extra-cflags=-I/usr/local/x264/include --extra-ldflags=-L/usr/local/x264/lib --prefix=/slq/local/ffmpeg

可以编译，但是没加上--enable-libmp3lame，加上后重新配置编译，我安装了yasm，把这个也打开

./configure --enable-libmp3lame --enable-memalign-hack --enable-ffserver --enable-network --enable-protocols --enable-muxers --enable-yasm --enable-shared --enable-w32threads --enable-libx264 --enable-gpl --extra-cflags=-I/usr/local/x264/include --extra-ldflags=-L/usr/local/x264/lib --prefix=/slq/local/ffmpeg

然后make&&make install即编译安装ffmpeg

记得修改系统变量 PATH

vi /etc/profile
加入以下内容:
  FFMPEG=/slq/local/ffmpeg
PATH加入:$FFMPEG/bin
  5.使修改立即生效
  source /etc/profile

执行
ffmpeg -version

出现错误

ffmpeg: error while loading shared libraries: libavdevice.so.55: cannot open shared object file: No such file or directory

ffmpeg: error while loading shared libraries: libx264.so.142: cannot open shared object file: No such file or directory

发现是没有添加动态链接库，根据网友总结

添加动态链接库
vi /etc/ld.so.conf
加入：/usr/local/ffmpeg/lib
执行
ldconfig

我的 /etc/ld.so.conf 文件下只有一行

include /etc/ld.so.conf.d/*.conf

所以进入到文件 /etc/ld.so.conf.d/libc.conf 中添加

/slq/local/ffmpeg/lib

/usr/local/x264/lib

执行

sudo ldconfig
