编译Android下可用的FFmpeg+x264
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
2.切换当前目录为该目录
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=$PLATFORM
make
sudo make install
sudo ldconfig
编译ffmpeg:
下载最新版的ffmpeg
http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
1.解压到指定的目录
2.切换当前目录为该目录
3.创建一个shell脚本build_ffmpeg.sh,内容如下:
#!/bin/bash export NDK=/home/duizhe/android-ndk-r6 export PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.4.3/prebuilt export PLATFORM=$NDK/platforms/android-8/arch-arm export PREFIX=/home/android-ffmpeg function build_one { ./configure --target-os=linux --prefix=$PREFIX \ --enable-cross-compile \ --enable-runtime-cpudetect \ --disable-asm \ --arch=arm \ --cc=$PREBUILT/linux-x86/bin/arm-linux-androideabi-gcc \ --cross-prefix=$PREBUILT/linux-x86/bin/arm-linux-androideabi- \ --disable-stripping \ --nm=$PREBUILT/linux-x86/bin/arm-linux-androideabi-nm \ --sysroot=$PLATFORM \ --enable-nonfree \ --enable-version3 \ --disable-everything \ --enable-gpl \ --disable-doc \ --enable-avresample \ --enable-demuxer=rtsp \ --enable-muxer=rtsp \ --disable-ffplay \ --disable-ffserver \ --enable-ffmpeg \ --disable-ffprobe \ --enable-libx264 \ --enable-encoder=libx264 \ --enable-decoder=h264 \ --enable-protocol=rtp \ --enable-hwaccels \ --enable-zlib \ --disable-devices \ --disable-avdevice \ --extra-cflags="-I/home/android-ffmpeg/include -fPIC -DANDROID -D__thumb__ -mthumb -Wfatal-errors -Wno-deprecated -mfloat-abi=softfp -mfpu=vfpv3-d16 -marm -march=armv7-a" \ --extra-ldflags="-L/home/android-ffmpeg/lib" make -j4 install $PREBUILT/linux-x86/bin/arm-linux-androideabi-ar d libavcodec/libavcodec.a inverse.o $PREBUILT/linux-x86/bin/arm-linux-androideabi-ld -rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -L$PREFIX/lib -soname libffmpeg.so -shared -nostdlib -z,noexecstack -Bsymbolic --whole-archive --no-undefined -o $PREFIX/libffmpeg.so libavcodec/libavcodec.a libavfilter/libavfilter.a libavresample/libavresample.a libavformat/libavformat.a libavutil/libavutil.a libswscale/libswscale.a -lc -lm -lz -ldl -llog -lx264 --warn-once --dynamic-linker=/system/bin/linker $PREBUILT/linux-x86/lib/gcc/arm-linux-androideabi/4.4.3/libgcc.a } build_one
编译完成。
