command line vlc --start-time not working

[insyzygy]

Hi,
I am using the "--video-filter=scene" option in command-line vlc.

The issue I am having is with the --start-time and --end-time parameters. I want to output screen caps between 23:10 (1390 secs) and 24:10 (14:50 secs). When I enter 1390 and 1450 as the respective parameters, the screen caps just start from start of the video and proceed through until the end (I guess). However, if I set the times to be, say 2 and 10 seconds, it runs fine: I get screen caps between 2 and 10 seconds...

I've tried 60 and 71 seconds and the screen caps range between 0 and 71 seconds...

Why will it not work between 1390 and 1450 seconds?! This is driving me crazy...

It appears to me that -start-time is just ignored... is this a bug?

thanks for any suggestions
Garret
