FFmpeg编译hevc版本，支持mac、linux系统

相关前置库

openssl

• 仓库：https://github.com/openssl/openssl.git
• 编译方式参考INSTALL.md中的步骤

 # Unix / Linux / macOS$ ./config$ make && sudo make install

lame库

• 如果需要处理mp3相关，依赖lame库， 仓库：https://sourceforge.net/projects/lame/
• mp3相关操作可以参考《ffmpeg转换mp3的实现》
• 编译方式

build_lame()
{echo "Build lame"if [ -f "${INSTALL_DIR}/lib/libmp3lame.a" ]; thenecho "Use built static libmp3lame.a"elseif [ -f "${THIRD_PARTY_DIR}/lame-3.100.tar.gz" ]; thenecho "exist lame source in 3rd dir, use it"tar -zxvf ${THIRD_PARTY_DIR}/lame-3.100.tar.gz -C $INSTALL_DIRelseecho "do not have lame source, need download"wget https://jaist.dl.sourceforge.net/project/lame/lame/3.100/lame-3.100.tar.gz -P ${THIRD_PARTY_DIR}fipushd $INSTALL_DIR/lame*os_type=$(uname)if [[ "$os_type" == "Darwin" ]]; thenXCRUN_SDK=`echo macosx | tr '[:upper:]' '[:lower:]'`CC="xcrun -sdk $XCRUN_SDK clang -arch x86_64"CFLAGS="-arch x86_64 $SIMULATOR"if ! xcodebuild -version | grep "Xcode [1-6]\."thenCFLAGS="$CFLAGS -fembed-bitcode"fiCXXFLAGS="$CFLAGS"LDFLAGS="$CFLAGS"CC=$CC ./configure --disable-shared --disable-frontend --host=x86_64-apple-darwin \--prefix=$INSTALL_DIR CC="$CC" CFLAGS="$CFLAGS" LDFLAGS="$LDFLAGS"elif [[ "$os_type" == "Linux" ]]; thenLDFLAGS="-fPIC" ./configure --prefix=$INSTALL_DIR --build=BUILD --enable-static --enable-nasm --with-picelseecho "Unknown operating system"fimake -jmake installpopdfi
}

x264库

• 如果需要x264，对应仓库：https://github.com/mirror/x264

build_x264()
{pushd $INSTALL_DIRecho "Build x264"if [ -d x264 ]; then echo "Use exists x264."elsegit clone -b master git@github.com:mirror/x264.gitfipushd x264if [ -f "${INSTALL_DIR}/lib/libx264.a" ]; thenecho "Use built static libx264.a"else./configure --prefix=$INSTALL_DIR \--enable-static \--enable-picfimake -jmake installpopdpopd
}

x265库

• 如果需要x265，到官网下载https://www.x265.org/downloads/

build_x265()
{pushd $INSTALL_DIRecho "Build x265"if [ -d x265 ]; then echo "Use exists x265."elseif [ -f "${THIRD_PARTY_DIR}/x265_v3.3.tar.gz" ]; thenecho "exist x265 in 3rd dir, use it"tar -zxvf $THIRD_PARTY_DIR/x265_v3.3.tar.gz -C $INSTALL_DIRelseecho "download x265 source code from https://www.x265.org/downloads/ and save it to 3rd dir, for example: 3rd/x265_v3.3.tar.gz"fi fipushd x265_3.3ln -sf $INSTALL_DIR/../scripts/x265_multilib.sh build/linux/x265_multilib.shif [ -f "${INSTALL_DIR}/lib/libx265.a" ]; thenecho "Use built static libx265.a"elsepushd build/linuxsh x265_multilib.sh $INSTALL_DIRpopdfipopdpopd
}

FFmpeg的编译

• 整理ffmpeg的编译相关build ffmpeg

# for debug, add --enable-debug --disable-stripping
build_ffmpeg()
