ffmpeg linux 静态库,Ubuntu ffmpeg编译静态库和共享库-Go语言中文社区
Ubuntu16.04 环境下编译ffmpeg生成静态库和共享库
基本上按照这个步骤编
Compile FFmpeg on Ubuntu,Debian,or Mint
Get the Dependencies
sudo apt-get update
sudo apt-get -y install autoconf automake build-essential libass-dev libfreetype6-dev
libsdl2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev
libxcb-xfixes0-dev pkg-config texinfo wget zlib1g-dev
Compilation & Installation
mkdir ~/ffmpeg_sources
任意指定一个目录即可
Yasm
强烈推荐使用，不然会编得很慢
An assembler for x86 optimizations used by x264 and FFmpeg. Highly recommended or your resulting build may be very slow.
If your repository provides yasm version ≥ 1.2.0 then you can install that instead of compiling:
sudo apt-get install yasm
或
cd ~/ffmpeg_sources
wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar xzvf yasm-1.3.0.tar.gz
cd yasm-1.3.0
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"
make
make install
nasm
使用x264的话就需要
NASM assembler. Required for compilation of x264 and other tools.
cd ~/ffmpeg_sources
wget http://www.nasm.us/pub/nasm/releasebuilds/2.13.01/nasm-2.13.01.tar.bz2
tar xjvf nasm-2.13.01.tar.bz2
cd nasm-2.13.01
./autogen.sh
PATH="$HOME/bin:$PATH" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"
PATH="$HOME/bin:$PATH" make
make install
libx264
H.264 video encoder. See the H.264 Encoding Guide for more information and usage examples.
Requires ffmpeg to be configured with –enable-gpl –enable-libx264.
If your repository provides libx264-dev version ≥ 118 then you can install that instead of compiling:
sudo apt-get install libx264-dev
或
cd ~/ffmpeg_sources
wget http://download.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
tar xjvf last_x264.tar.bz2
cd x264-snapshot*
PATH="$HOME/bin:$PATH" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static --disable-opencl
PATH="$HOME/bin:$PATH" make
make install
以下的库有选择地安装吧，有些音频的库用不到，都安装也可以，注意看英文说明，哪个需要在运行configure文件的时候，enable一下
libx265
H.265/HEVC video encoder. See the H.265 Encoding Guide for more information and usage examples.
If your repository provides libx265-dev version ≥ 68 then you can install that instead of compiling:
sudo apt-get install libx265-dev
或
sudo apt-get install cmake mercurial
cd ~/ffmpeg_sources
hg clone https://bitbucket.org/multicoreware/x265
cd ~/ffmpeg_sources/x265/build/linux
PATH="$HOME/bin:$PATH" cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$HOME/ffmpeg_build" -DENABLE_SHARED:bool=off ../../source
make
make install
libfdk-aac
AAC audio encoder. See the AAC Audio Encoding Guide for more information and usage examples.
Requires ffmpeg to be configured with –enable-libfdk-aac (and –enable-nonfree if you also included –enable-gpl).
If your repository provides libfdk-aac-dev then you can install that instead of compiling:
sudo apt-get install libfdk-aac-dev
或
cd ~/ffmpeg_sources
wget -O fdk-aac.tar.gz https://github.com/mstorsjo/fdk-aac/tarball/master
tar xzvf fdk-aac.tar.gz
cd mstorsjo-fdk-aac*
autoreconf -fiv
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install
libmp3lame
MP3 audio encoder.
Requires ffmpeg to be configured with –enable-libmp3lame.
If your repository provides libmp3lame-dev version ≥ 3.98.3 then you can install that instead of compiling:
sudo apt-get install libmp3lame-dev
或
cd ~/ffmpeg_sources
wget http://downloads.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gz
tar xzvf lame-3.99.5.tar.gz
cd lame-3.99.5
./configure --prefix="$HOME/ffmpeg_build" --enable-nasm --disable-shared
make
make install
libopus
Opus audio decoder and encoder.
Requires ffmpeg to be configured with –enable-libopus.
If your repository provides libopus-dev version ≥ 1.1 then you can install that instead of compiling:
sudo apt-get install libopus-dev
或
cd ~/ffmpeg_sources
wget https://archive.mozilla.org/pub/opus/opus-1.1.5.tar.gz
tar xzvf opus-1.1.5.tar.gz
cd opus-1.1.5
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install
libvpx
VP8/VP9 video encoder and decoder. See the VP8 Video Encoding Guide for more information and usage examples.
Requires ffmpeg to be configured with –enable-libvpx.
If your repository provides libvpx-dev version ≥ 0.9.7 then you can install that instead of compiling:
sudo apt-get install libvpx-dev
或
sudo apt-get install git
cd ~/ffmpeg_sources
git clone --depth 1 https://chromium.googlesource.com/webm/libvpx.git
cd libvpx
PATH="$HOME/bin:$PATH" ./configure --prefix="$HOME/ffmpeg_build" --disable-examples --disable-unit-tests
PATH="$HOME/bin:$PATH" make
make install
最后，ffmpeg
cd ~/ffmpeg_sources
wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
tar xjvf ffmpeg-snapshot.tar.bz2
cd ffmpeg
PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig"
在解压后的ffmpeg目录下面有configure文件，打开或者运行./configure –help可看到使用说明，以下是官方文档中的配置，其中–pkg-config-flags=”–static”一句表明只生成静态库.a，若想生成共享库.so，或者都生成，参考文章最后的配置。
./configure
--prefix="$HOME/ffmpeg_build" --pkg-config-flags="--static" --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" --bindir="$HOME/bin" --enable-gpl --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfreePATH="$HOME/bin:$PATH" make
make install
hash -r
只生成静态库.a：使用以上配置
只生成共享库.so：
删去–pkg-config-flags=”–static”一句
使用–enable-shared –disable-static
静态库.a和共享库.so都声称：
删去–pkg-config-flags=”–static”一句
仅使用–enable-shared(两条-)
最终，在~/ffmpeg-build/lib目录下，可查看到生成的相关库。
注：生成的.so有一些是.so.*形式的扩展名，如不想生成此种形式，需要修改configure文件。
贴出网上的一种改法：
将该文件中的如下四行：
SLIBNAME_WITH_MAJOR=’(SLIBNAME).(LIBMAJOR)’
LIB_INSTALL_EXTRA_CMD=’$$(RANLIB)”$(LIBDIR)/$(LIBNAME)”’
SLIB_INSTALL_NAME=’$(SLIBNAME_WITH_VERSION)’
SLIB_INSTALL_LINKS=’(SLIBNAMEWITHMAJOR)(SLIBNAME)’
替换为：
SLIBNAME_WITH_MAJOR=’(SLIBPREF)(FULLNAME)-(LIBMAJOR)(SLIBSUF)’
LIB_INSTALL_EXTRA_CMD=’$$(RANLIB)”$(LIBDIR)/$(LIBNAME)”’
SLIB_INSTALL_NAME=’$(SLIBNAME_WITH_MAJOR)’
SLIB_INSTALL_LINKS=’$(SLIBNAME)’
如果想撤销以上所有操作对你的系统造成的改变，使用以下命令
rm -rf ~/ffmpeg_build ~/ffmpeg_sources
~/bin/{ffmpeg,ffprobe,ffplay,ffserver,x264,x265,nasm}
sudo apt-get autoremove autoconf automake build-essential cmake libass-dev libfreetype6-dev
libmp3lame-dev libopus-dev libsdl2-dev libtheora-dev libtool libva-dev libvdpau-dev
libvorbis-dev libvpx-dev libx264-dev libxcb1-dev libxcb-shm0-dev ibxcb-xfixes0-dev mercurial texinfo zlib1g-dev
sed -i '/ffmpeg_build/c' ~/.manpath
hash -r
