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

  1. [StevenLiu@liudeMacBook-Pro ffmpeg]$ ./configure --help
  2.   --enable-libstagefright-h264 enable H.264 decoding via libstagefright [no]
  3.   --enable-libx264 enable H.264 encoding via x264 [no]
  4.  --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:

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

  1. ./configure
  2. make
  3. make install


安装libx264编码库

 孙悟空

点击(此处)折叠或打开

  1. ./configure
  2. make
  3. make install


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

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
