[FFmpeg-user] -t option is ignored

[Steve Cookson]

I forgot to add console output. (See below).

************************************

Hi Guys,

There is no indication whether this issue was every resolved here and I have
the same problem.

I tried all the options in the thread with the same results.

If I try:

> Could you try moving the -ss and -t after the -i now?

I get file '-ss' not found.

This is what I think should be correct:

( I have input.avi 60s in duration and output.avi should be 20s but is 55s
long).

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

Regards

Steve
