Hi, i need a way to extract just one thumbnail just on one specified time from the video.

I have tryed with this one:

vlc -V image --start-time 5 --stop-time 6 --image-out-format jpg --image-out-ratio 25--snapshot-width 720 --snapshot-height 0 --image-out-prefix D:\Movies\thumb_ D:\Movies\movie1.ts vlc://quit

it shoul be take the thumb at second 5 and quits vl after that, but it starts from begin, takes every second one thumb and doesnt exit vl...!?!?

can i specify to go directly so second x from the video and take only one thumb, without hearing the audio?

Thank you for any hints :mrgreen:

--start-time is broken in VLC 0.9.8a. Fixed in 0.9.9/1.0.0. Try a nightly build of VLC 0.9.9-rc2 (in the "branch-" directories):

For no audio use:

Code: Select all

--no-audio

--start-time is still broken. I've tested the nightly versions from 8-Mar to 10-Mar and I still can't get it to work. I've been using vlc 0.8.6h because it works there so I know my command line usage is correct. This bug is the only thing preventing me from using a later version. Additionally, in version 8.6h --start-time is broken when a value of 4295 (or more) is used.

Have you tried with the "trunk" builds (VLC 1.0.0-git) as well?

Time options won't work with TS files, because VLC doesn't know the length of those files.

Just tested --start-time with both the latest 0.9.9-rc2 nightly and 1.0.0-git nightly. Both work fine via commandline.
