在Ubuntu下编译FFmpeg

第一步:准备编译环境

sudoapt-get update   sudo apt-get -y install autoconf automake build-essential git libass-dev libfaac-dev \   libgpac-dev libjack-jackd2-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev \   librtmp-dev libsdl1.2-dev libspeex-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev \   libx11-dev libxext-dev libxfixes-dev pkg-config texi2html zlib1g-dev   sudo ldconfig

在home下新建一个目录用于存放下载的源码:

mkdir ~/ffmpeg-setup

[编辑]第二步:安装x264和FFmpeg要用到的汇编器yasm

tar-zxf yasm-1.2.0.tar.gz cd yasm-1.2.0/ ./configure --prefix=/usr/localmakesudomakeinstall

[编辑]第三步:编译x264

tar-jxf x264-20130217.tar.bz2 cd x264-snapshot-20130217-2245/ ./configure --enable-static--enable-shared--prefix=/usr/localmakesudomakeinstall

[编辑]第四步:编译fdk-aac

tar-zxf fdk-aac-0.1.1.tar.gz cd fdk-aac-0.1.1/ autoreconf –fiv ./configure --prefix=/usr/localmakesudomakeinstall

[编辑]第五步:编译FFmpeg

tar-jxf ffmpeg-1.1.3.tar.bz2 cd ffmpeg-1.1.3/   ./configure --enable-gpl--enable-libass--enable-libfaac--enable-libfdk-aac--enable-libmp3lame \   --enable-libopencore-amrnb--enable-libopencore-amrwb--enable-libspeex--enable-librtmp--enable-libtheora \   --enable-libvorbis--enable-x11grab--enable-libx264--enable-nonfree--enable-version3  \   --enable-shared--prefix=/usr/local

去掉--disable-optimizations --disable-asm,并加上-enable-shared --prefix=/usr/local选项

makesudomakeinstallsudo ldconfig

编译完成,输入ffmpeg结果如下:
