海思Hi3536交叉编译ffmpeg 和OPencv

1 海思Hi3536交叉编译x264库

1. 下载x264 https://code.videolan.org/videolan/x264

编译和安装
x264编译

编译之前先给.sh 文件权限，
先执行 version.sh
在执行
CC=arm-himix200-linux-gcc   ./configure \
--host=arm-himix200-linux \
--prefix=$OPENCV_DEPEND  \
--cross-prefix=arm-himix200-linux- \
--enable-static \
--enable-shared \

make
make install

2 海思Hi3536交叉编译 ffmpeg
