Make thumbnails without playing video?

[popovaksiusha912]

Code: Select all

vlc "target.flv" --rate=1 --video-filter=scene --scene-format=png --scene-ratio=24 --scene-prefix=snap --scene-path="C:\output" vlc://quit

Code above can make thumbnails correctly, but it will play video and cost too much time.

If I use this code to make thumbnails for a 10 hours duration video, then it costs 10 hours.
If I use this code to make thumbnails for a 100 hours duration video, then it costs 100 hours.

This is unacceptable.
Is there any faster way to make thumbnails using vlc?
