目录下视频批量截图脚本，转码，上传到阿里OSS

这是之前开发的一个项目的时候写的，脚本批量将目录里的视频批量的截图 ，用到了 ffmpeg 转码工具
截图脚本事例：

#!/bin/bash

run_ls(){
        pwd;

        for x in $(ls -l| grep ".mp4$" | awk '{print $9}')
        do
            echo $x
            ffmpeg -y -i $x -frames 1 -f image2 $x".jpg"
        done
}

myfunc(){
        cd $1;
        #run_make;
        run_ls;

        for x in $(ls .)
        do
                if [ -d "$x" ];then
                        myfunc $x;
                        cd ..
                fi

        done
}

p=.
if [ $1 ];then
    p=$1
fi
echo $p

myfunc $p

转码并上传到OSS：
