I am trying to encode a bunch of jpg files using the following command:

mencoder mf://*.jpg -mf w=800:h=600:fps=25:type=jpg -ovc lavc
-lavcopts vcodec=mpeg4:mbd=2:trell -oac copy -o output.avi

I got this command from here:

http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-enc-images.html

I get the following results:

$ mencoder mf://*.jpg -mf w=800:h=600:fps=25:type=jpg -ovc lavc
-lavcopts vcodec=mpeg4:mbd=2:trell -oac copy -o output.avi

I've been following this mailing list for a month or so but this is
the first time I really try out mencoder, so I don't really know what
is going on. Can you help me?
