[MEncoder-users] set duration when converting jpeg to video

[Peter Falk]

Hello,

I try to convert a single JPEG file to a video with the following command:

mencoder mf://xy.jpg -mf w=800:h=600:fps=25:type=jpg -ovc lavc -lavcopts 
vcodec=mpeg4 -oac copy -o output.avi/

/But the duration ist only 0,040 sec. How can I set a duration of e.g. 
15 sec.?/

/Thanks for your help

  Peter
