FFmpeg編譯記錄

參照官方wiki編譯，鏈結為:

一、copy and paste the whole code box for each step.

sudo apt-get update

sudo apt-get -y install autoconf automake build-essential git libass-dev libgpac-dev \
libsdl1.2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libx11-dev \
libxext-dev libxfixes-dev pkg-config texi2html zlib1g-dev
mkdir ~/ffmpeg_sources

二、compilation&installation

2.1yasm

yasm is an assembler used by x264 and ffmpeg.

cd ~/ffmpeg_sources

wget 
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
. ~/.profile

2.2 x264

h.264 video encoder. see the x264 encoding guide for more information and examples.

cd ~/ffmpeg_sources

git clone --depth 1 git:
cd x264
./configure --prefix="$home/ffmpeg_build" --bindir="$home/bin" --enable-static
make
make install
make distclean

if you really want to compile without asm, configure with --disable-asm.

解決方法

回到yasm-1.2.0目錄下

./configure --prefix=/usr --enable-shared 

重新編譯

2.3 fdk-aac

aac audio encoder. see the aac encoding guide for more information and examples.

cd ~/ffmpeg_sources

git clone --depth 1 git:
cd fdk-aac
autoreconf -fiv
./configure --prefix="$home/ffmpeg_build" --disable-shared
make
make install
make distclean

2.4 lib***lame

*** audio encoder.

sudo apt-get install lib***lame-dev

sudo apt-get install nasm

cd ~/ffmpeg_sources
wget 
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
make distclean

2.5 libopus

opus audio decoder and encoder.

cd ~/ffmpeg_sources

wget 
tar xzvf opus-1.0.3.tar.gz
cd opus-1.0.3
./configure --prefix="$home/ffmpeg_build" --disable-shared
make
make install
make distclean

2.6 libvpx

vp8/vp9 video encoder and decoder. see the vpx (webm) encoding guide for more information and examples.

cd ~/ffmpeg_sources

git clone --depth 1 
cd libvpx
./configure --prefix="$home/ffmpeg_build" --disable-examples
make
make install
make clean

2.7 ffmpeg

cd ~/ffmpeg_sources

git clone --depth 1 git:
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-libass --enable-libfdk-aac \
--enable-lib***lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx \
--enable-libx264 --enable-nonfree --enable-x11grab
make
make install
make distclean
hash -r

完成後可執行檔案位於~/bin目錄下

官方wiki建議使用gcc4.2 ，已嘗試使用gcc-4.2.3在編譯libvpx時出錯，故放棄

現已測試編譯環境為:

ubuntu11.04 bit64 、gcc4.5.2

ubuntu12.04 bit32、gcc-4.6

ubuntu12.04 bit64、gcc-4.6(待測試)

FFMPEG交叉編譯記錄

記錄一下自己踩過的坑，linux小白 1 ndk版本17之後使用clang編譯器，不使用gcc 2 初裝linux可能未安裝clang編譯器，需要先檢查下 終端輸入clang，若提示 not input file 則已安裝 sudo yum install epel release sudo yum...
