echo "验证"

echo "/usr/local/ffmpeg/lib" >> /etc/ld.so.conf.d/ffmpeg.conf

cd /usr/local/ffmpeg/bin

###运行

###./ffmpeg -version

###报错：

###libavdevice.so.57: cannot open shared object file: No such file or directory，原因是lib目录未加载到链接到系统库中

###解决：

###vim /etc/ld.so.conf.d/ffmpeg.conf

###加入  /usr/local/ffmpeg/lib

###保存

echo "使配置生效ldconfig"

ldconfig

###运行

./ffmpeg -version

sleep 3

###vim /etc/profile

###加入： 

echo "传入环境变量""

####ffmpeg

echo "#ffmpeg" >> /etc/profile

###echo "export FFMPEG_HOME=/usr/local/ffmpeg/" >> /etc/profile

###echo "export PATH=$PATH:$FFMPEG_HOME/bin" >> /etc/profile

echo "export PATH=/usr/local/ffmpeg/bin:$PATH" >> /etc/profile

source /etc/profile

###音频格式转换测试：

###ffmpeg -i test.avi out.mp4

###opencv安装(视频提取)

echo "opencv安装"

yum install  gcc  gcc-c++ cmake* unzip -y

##yum install cmake gcc gcc-c++ gimp-devel gimp-devel-tools gimp-help-browser zlib-devel libtiff-devel libjpeg-devel libpng-devel gstreamer-devel libavc1394-devel libraw1394-devel libdc1394-devel jasper-devel jasper-utils swig  libtool nasm build-essential unzip

###gtk2.0使用yum安装

echo "gtk2.0使用yum安装"

yum install gtk2-devel -y

###安装ant，使得opencv编译java接口包

echo "安装ant，使得opencv编译java接口包"

yum install ant -y

##下载opencv安装包

echo "下载opencv安装包"

cd /opt

wget https://github.com/opencv/opencv/archive/3.4.1.zip

unzip 3.4.1.zip

mv opencv-3.4.1 /usr/local/src/

cd /usr/local/src/opencv-3.4.1

###判断文件是否存在CMakeCache.txt

echo "判断文件是否存在CMakeCache.txt,存在则删除"

if [ -f "/usr/local/src/opencv-3.4.1/CMakeCache.txt" ];then

echo "文件存在"

echo "rm -rf /usr/local/src/opencv-3.4.1/CMakeCache.txt"

else

echo "文件不存在"

fi

echo "创建build目录"

mkdir build

cd build

##编译

cmake -DBUILD_SHARED_LIBS=OFF -DBUILD_TESTS=OFF -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local/opencv ..

###（如果报错：FATAL: In-source builds are not allowed , You should create a separate directory for build files.

###则把 opencv3.4.1/cMakeCache.txt 删除后再试）

###（IPPICV: Download: ippicv_2017u2_lnx_intel64_20170418.tgz ，速度有点慢，多等一会儿）
