[MEncoder-users] newbie help request - can't compile JPGs into movie

Hi, nice to meet you all

I'm trying to use mencoder to compile any number of .JPG images, with
varying but incomplete results. Please can anyone suggest what might be
going wrong for me?

OS: Ububtu 7.10
Mencoder version 2:1.0~rc1-0ubuntu13.2


When I try executing (1), it creates a zero size .avi output file, and
dumps the core giving (2):

(1)
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


(2)

mencoder(read_font_desc_ft+0x4c2)[0x80c16e2]


I've had a good look for missing libraries, but can't see what's going
wrong.

Thanks in advance

Matt
