群晖（Synology）video Station索引无视频缩略图

一、个人环境

黑群晖DSM6.1.4

二、解决方式

1、参考上文，下载新版本ffmpeg

https://www.cnblogs.com/hester/p/14696235.html

2、编写python脚本，调用ffmpeg截取视频图像

三、解决步骤

目前群晖DSM自带的ffmpeg版本是 2.7.1 ，通过社区第三方安装 4.2.4 版本的ffmpeg，Photo Station索引后，可以生成视频缩略图；但Video Station索引后，仍然无法生成视频缩略图。

个人的解决方式为编写python转换脚本

1、下载新版ffmpeg

如何下载、安装，请参考：https://www.cnblogs.com/hester/p/14696235.html

2、编写python转换脚本

创建脚本文件photo_thumb.py

3、上传至群辉共享文件夹

• 打开File Station，上传脚本文件photo_thumb.py至需要转换的文件夹，如video

• 脚本执行时，会自动遍历子文件夹，所以只需在最外层文件夹执行即可

4、进入步骤3中video文件夹，运行脚本

ssh登录群辉，如何设置、登录，请参考https://www.cnblogs.com/hester/p/14696235.html

ssh命令行窗口运行如下命令

cd / cd volume1/video/ sudo python3 photo_thumb.py

注：如上脚本采用python3执行，python2未实验
