Black Synology generates video thumbnails with one click

question

When we use VideoStation, if the upload is not a film and television drama, etc., there is no way to automatically find the thumbnail of the poster, so we made a tutorial here. Use FFmpeg , Python respectively

solution

1. Enter the Synology system
[the yellow highlighter marks the place that needs to be clicked]

2. Add the source

name of the third-party package with the same name as the location.

Location URL:
[DSM6.x version]

https://spk.imnks.com/

[DSM7.x version]

https://spk7.imnks.com/

3. To install the software package
, click the community
to search for ffmpeg and install it.

4. Enable the Synology SSH function.
Please see the following figure for the operation steps. 5.

Use the SSH tool to connect
to Synology . Account Enter the password of the group management account and log in successfully 6. Add Python files and copy all

enter to find your own video storage location, method: the folders starting with volume are all hard disks, ls /volume a few times, you can find the location where the video is stored

press Enter, press i , right-click and copy a lot of code just copied into the terminal,

press ESC , enter : wq, and press Enter. Note that it is the English
