Hi Carl,

>> ffmpeg version 0.7.3-4:0.7.3-0ubuntu0.11.10.1
> please see http://ffmpeg.org/download.html for supported versions.

Thanks for this.   

Really I need a stable version and I am a little surprised that Ubuntu
doesn't use one, why would they not use one of, for instance:

- FFmpeg 0.9.1 "Harmony"
- FFmpeg 0.10.2 "Freedom"?

Anyhow we are where we are.  Next time I do a rebuild, I will consider
whether I can move to a stable supported release of FFmpeg.

In the meantime if I use the idea that $frames = int($clip_duration * fps)
and I do 

ffmpeg -ss 5 -i input.avi -vframe 200 -vcodec huffyuv -r10 -sameq -an -y
output.avi

Instead of 

ffmpeg -ss 5 -t 20 -i input.avi -vcodec huffyuv -r10 -sameq -an -y
output.avi

And this works, so thanks very much for your help all.

Regards

Steve
