平时用的x264编码器有分普通x264、tmod、kmod。
这些编码器都有现成的win平台可执行文件，但是当我想要在Linux平台上使用的时候，那就需要自行编译了。
由于编译根据Linux发行版本、编译环境不同可能会发生各种问题。
笔记来源于http://mom.blog.ustc.edu.cn/?p=163但是由于年代久远（也就2013年至今），代码等等发生了变化，全盘按照此教程编译一定是失败的。于是我给出了如下可能的编译方案
编译平台Debian 8
Contents
1.依赖准备：
sudo apt-get install autoconf automake git libtool nasm build-essential pkg-config libssl-dev zlib1g-dev
注：gcc版本最好更新，否则有可能出现报错
2.建立代码库文件夹
mkdir ~/ffmpeg_sources
3.yasm安装或者yasm编译
a.安装：
sudo apt-get install yasm
b.编译：
cd ~/ffmpeg_sources curl -O http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gz tar xzvf yasm-1.2.0.tar.gz cd yasm-1.2.0 ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" make make install make distclean
4.ffmpeg编译
cd ~/ffmpeg_sources git clone --depth 1 git://source.ffmpeg.org/ffmpeg cd ffmpeg PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" export PKG_CONFIG_PATH ./configure --prefix="$HOME/ffmpeg_build" --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" --bindir="$HOME/bin" --extra-libs="-ldl" --enable-gpl --enable-nonfree make make install make distclean
5.编译ffms2
cd ~/ffmpeg_sources git clone https://github.com/FFMS/ffms2.git cd ffms2 ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static --disable-shared make make install make distclean
6.编译l-smash
cd ~/ffmpeg_sources git clone https://github.com/l-smash/l-smash.git cd l-smash/ ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" make make install-lib install -m 644 ./importer/importer.h ~/ffmpeg_build/include/lsmash_importer.h make distclean
7.编译x264_tMod
首先要准备好文件x264_tMod-clone.sh,参考 http://astrataro.wordpress.com 需要翻墙，全文见附录,假设x264_tMod-clone.sh已经下载到~/ffmpeg_sources目录下
cd ~/ffmpeg_sources sh x264_tMod-clone.sh cd x264_tMod/ ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --chroma-format=420 --bit-depth=8 --enable-strip --disable-audio --disable-opencl make make install make distclean

这个修改自原Shell脚本，由于年久失修，DarkShikari的x264-devel已经404了，临时找来一个可以用的。

根据上面方案，最终测试，最后的x264任然无法正常编译，因此搜寻了新的替代方案：
Fork了一个含有tmod的x264代码，编译出来有aq-mode3
