1.下载linux ndk并配置profile文件
本例以android-ndk-r10e为例
vi /etc/profile
export NDK_HOME=/root/ffmpeg/android-ndk-r10e
export PATH= P A T H : PATH: PATH:NDK_HOME
source /etc/profile
2.下载x264并生成
git clone https://code.videolan.org/videolan/x264.git
cd x264/
./configure --prefix=/root/ffmpeg/outputx264 --enable-shared --enable-static --disable-asm
make
make install
3.下载fdk-aac并生成
git clone --depth 1 https://gitee.com/mirrors/fdk-aac.git
cd fdk-aac/
./autogen.sh
sudo apt-get install autoconf
sudo apt-get install automake
sudo apt-get install libtool
./autogen.sh
./configure --enable-shared --prefix=/root/ffmpeg/outputfdk
make
make install
4.下载lame并生成
wget http://downloads.sourceforge.net/project/lame/lame/3.100/lame-3.100.tar.gz
tar zxvf lame-3.100.tar.gz
cd lame-3.100/
./configure --enable-shared --enable-static --prefix=/root/ffmpeg/outputlame
make
make install
5.最后编译ffmpg
