./configure --prefix=/usr/local/ffmpeg --enable-pic --enable-shared --enable-gpl --enable-nonfree --enable-postproc --enable-pthreads --enable-libmp3lame --enable-libx264 --enable-libxvid --enable-x11grab

1.  Download yasm source code from `http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gz`
2.  Unpack `tar xvzf yasm-1.2.0.tar.gz`
3.  `cd yasm-1.2.0`
4.  Configure and build:
    
    `./configure && make -j 4 && sudo make install`

1、下载ffmpeg-2.6.3.tar.bz2、last\_x264.tar.bz2、yasm-1.2.0.tar.gz http://download.csdn.net/detail/xl4025/8919329  
2、libx264需要yasm,所以先安装yasm  
3、安装ffmpeg的依赖包  
libfaac、libmp3lame、libtheora、libvorbis、libxvid、libxext、libxfixes

wget https://www.nasm.us/pub/nasm/releasebuilds/2.14rc0/nasm-2.14rc0.tar.gz

tar xzf nasm-2.14rc0-xdoc.tar.bz2

cd nasm\*

./configure;make;sudo make install

wget ftp://ftp.videolan.org/pub/x264/snapshots/last\_x264.tar.bz2

tar xfj last\_x264.tar.bz2;

cd x264-\*

sudo apt-get install libx264-dev libfaac-dev libmp3lame-dev libtheora-dev libvorbis-dev libxvidcore-dev libxext-dev libxfixes-dev  
  
  
4、解压ffmpeg  
tar -xjvf ffmpeg-2.6.3.tar.bz2  
对ffmpeg进行编译安装  
./configure --prefix=/usr/local/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  
  
  
make  
make install  
  
  
5、当中问题  
1）、执行 ffmpeg -i "/home/user/down/flv/001.flv" -acodec copy -vcodec libx264 -b 560k -bf 6 -s 682\*310 -f mp4 "/home/user/test/001.mp4"遇到错误  
Unknown encoder 'libx264' 错误 由于已经安装过libx264、迷茫找了很久找到  
Unknown encoder 'libx264'. Installing the package libavcodec-extra-53  
In Ubuntu 14.04 LTS the package that is needed is called libavcodec-extra-54 (and libav-tools)  
安装libavcodec-extra-53  
apt-get install libavcodec-extra-53  
  
  
进入到  
/usr/local/ffmpeg/bin 目录下把  
复制到/usr/local/bin下  
在命令中直接运行  
ffmpeg
