1、下載最新的yasm1.20,編譯安裝（最新的x264會(huì)用到）
http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gz
2、下載最新的x264
export PATH=$PATH:/home/xy/mywork/av/yasm-1.2.0./configure --enable-gpl

3、下載最新的libav
sudo apt-get install libsdl1.2-dev (avplay 編譯使用)http://libav.org/releases/libav-snapshot.tar.bz2 export PATH=$PATH:/home/xy/mywork/av/yasm-1.2.0 ./configure --enable-gpl --enable-libx264 --extra-cflags="-I/home/xy/mywork/av/x264-snapshot-20140218-2245" --extra-ldflags="-L/home/xy/mywork/av/x264-snapshot-20140218-2245" --extra-libs="-ldl"

其中：

1、編譯加--enable-libx264選項(xiàng)時(shí)要加--enable-gql；為了找到x264要加上--extra-cflags和--extra-ldflags,要編譯x264不出錯(cuò)；要加上--extra-libs="-ldl"

configure的結(jié)果：
