I noticed that thumbnails of videos are generated when I open my file explorer (Thunar).
I guess it uses external package such as tumbler and/or ffmpegthumbnailer
But I don’t know how to check the code of tumbler to execute it by myself from my command line terminal, without opening my Thunar file explorer…
Any idea?
I know I could use the command ffmpeg but it asks to choose when to do the screenshot in the video with the statement -ss, but I don’t want to choose it arbitrary, I prefer when tumbler chooses the right moment (maybe the middle of the video?) to do it.
Thanks for your help
