ffmpeg 和 opencv 编译

一、ffmpeg编译

ffmpeg 编译参数：

./configure  --enable-gpl --disable-x86asm --enable-shared  --enable-pic --enable-static
 

二、opencv编译

1、安装依赖库

 sudo apt-get install build-essential

    sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

    sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

 

2、编译参数

cmake -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules ../

 

3、编译问题

fatal error: vgg_generated_120.i: No such file or directory

一些文件因为下载失败，导致编译失败，从以下链接下载这些文件，放到opensource\opencv_contrib\modules\xfeatures2d\src  目录下就可以了
