ffmpeg not working right

[youradds]

Hi,

Not sure this is the right forum to post in (but I found a post relating to ffmpeg in here before, so am hoping it is =))

I'm using the following SSH command to make a video screenshot:

ffmpeg -i /home/projects/domains/domain.com/public_html/cgi-bin/tube/admin/get_screenshots/tmp/464_st.flv -y -f image2 -ss 12 -sameq -t 0.001 -s 320*240 /home/projects/domains/domain.com/public_html/static/shots/xx.jpg

...Now, this doesn't seem to work :/

However, using the same command with another .flv movie, and it works fine. After some debugging - the output from 2 example calls (one working, and one not) are below:

Can anyone see the problem? I'm hoping its just an issue with how we are calling it (rather than a problem with the .flv movies) ... as the movies are hosted by the websites, rather than us, so we can't fix any problems with the movies

TIA!
