ubuntu下编译ffmpeg with libx264

Preparation

Remove any existing packages:

sudo apt-get remove ffmpeg x264 libav-tools libvpx-dev libx264-dev yasm

Get the dependencies (Ubuntu Desktop users):

sudo apt-get update

sudo apt-get -y install autoconf automake build-essential checkinstall 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

Installation

Yasm

Yasm is an assembler and is recommended for x264 and FFmpeg.

cd  //回到用户家目录

wget 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

make

sudo checkinstall --pkgname=yasm --pkgversion="1.2.0" --backup=no \

  --deldoc=yes --fstrans=no --default

x264

H.264 video encoder. The following commands will get the current source files, compile, and install x264.

cd

git clone --depth 1 git://git.videolan.org/x264.git

cd x264

./configure --enable-static

make

sudo checkinstall --pkgname=x264 --pkgversion="3:$(./version.sh | \

  awk -F'[" ]' '/POINT/{print $4"+git"$5}')" --backup=no --deldoc=yes \

  --fstrans=no --default

//我用的选项

--enable-shared   (--enable-debug)

FFmpeg

Note: Ubuntu Server users should remove --enable-x11grab from the following command:

cd

git clone --depth 1 git://source.ffmpeg.org/ffmpeg

cd ffmpeg

./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-libvpx --enable-x11grab --enable-libx264 --enable-nonfree --enable-version3

make

sudo checkinstall --pkgname=ffmpeg --pkgversion="7:$(date +%Y%m%d%H%M)-git" --backup=no \

  --deldoc=yes --fstrans=no --default

hash –r

我用的选项

./configure --enable-gpl --enable-libfaac --enable-x11grab --enable-libx264 --enable-nonfree --enable-version3

Finish

Installation is now complete and FFmpeg is now ready for use.

测试x264是否支持mp4 output，然后再次编译使其支持 lavf

x264 --video-filter resize:width=352,height=288,method=spline -o /home/ray/media/Linux.mp4 /mnt/hgfs/share/test.mpg

输入x264 –help

Infile can be raw (in which case resolution is required),

  or YUV4MPEG (*.y4m),

  or Avisynth if compiled with support (yes).

  or libav* formats if compiled with lavf support (no) or ffms support (no).

Outfile type is selected by filename:

 .264 -> Raw bytestream

 .mkv -> Matroska

 .flv -> Flash Video

 .mp4 -> MP4 if compiled with GPAC support (yes)

Add lavf support to x264 (Re-compile x264)

This allows x264 to accept just about any input that FFmpeg can handle and is useful if you want to use x264 directly.

cd ~/x264

make distclean

./configure --enable-static

make

sudo checkinstall --pkgname=x264 --pkgversion="3:$(./version.sh | \

  awk -F'[" ]' '/POINT/{print $4"+git"$5}')" --backup=no --deldoc=yes \

  --fstrans=no –default

再次测试之

输入x264 –help

Infile can be raw (in which case resolution is required),

  or YUV4MPEG (*.y4m),

  or Avisynth if compiled with support (yes).

  or libav* formats if compiled with lavf support (yes) or ffms support (no).

Outfile type is selected by filename:

 .264 -> Raw bytestream

x264 --video-filter resize:width=352,height=288,method=spline -o /home/ray/media/Linux.mp4 /mnt/hgfs/share/test.mpg

成功转换出mp4

【附】第一次编译x264与第二次编译区别

x264 can use LAVF input if it detects a usable install of FFmpeg. Notice that the first x264 set was issued before compiling FFmpeg, therefore it will not have the option of using LAVF to open files. The later step recompiles x264 after FFmpeg is installed, detecting LAVF automatically.

LAVF input (and FFMS input, if that had been covered) allows the user to give x264 any general video file directly. Any way you look at the steps though, a recompile is going to be necessary somewhere in the process. Either x264 has to be rebuilt (as per this guide), or FFmpeg has to be rebuilt (in cases where the user wants to keep the LAVF and FFMS components streamlined, and needs a stripped-down version of FFmpeg).
