編譯Android的FFmpeg+x264 @ 自由手記

编译x264:

下载最新版的x264

ftp://ftp.videolan.org/pub/videolan/x264/snapshots/

1.解压到指定的目录

3.创建一个shell脚本build_x264.sh，内容如下：

NDK= NDK=/home/duizhe/android-ndk-r6（你自己的NDK根目录)

PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.4.3/prebuilt

PLATFORM=$NDK/platforms/android-8/arch-arm (or any other android platform you want)

PREFIX=/home/android-ffmpeg

./configure --prefix=$PREFIX \

--enable-static \

--enable-pic \

--disable-asm \

--disable-cli \

--host=arm-linux \

--cross-prefix=$PREBUILT/linux-x86/bin/arm-linux-androideabi- \

--sysroot=$PLATFORM

make

sudo make install

sudo ldconfig

编译ffmpeg:

下载最新版的ffmpeg

http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2

1.解压到指定的目录

3.创建一个shell脚本build_ffmpeg.sh，内容如下：
