android編譯ffmpeg+x264

編譯x264:
下載最新版的x264
ftp://ftp.videolan.org/pub/videolan/x264/snapshots/
1.解壓到指定的目錄
2.切換目前的目錄為該目錄
3.建立一個shell指令碼build_x264.sh，內容如下：

export NDK=/home/robin/案頭/android-ndk-r8cexport PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.4.3/prebuiltexport PLATFORM=$NDK/platforms/android-8/arch-arm export PREFIX=/home/robin/android-x264./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

執行如下命令編譯和安裝
make
sudo make install
sudo ldconfig
編譯ffmpeg:
下載最新版的ffmpeg
http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
1.解壓到指定的目錄
2.切換目前的目錄為該目錄
3.建立一個shell指令碼build_ffmpeg.sh，內容如下：

執行build_ffmpeg.sh編譯完成，編譯輸出在$PREFIX指定的目錄
