Spumux issues

[shendric]

Hi all,

Has anyone here tried to author DVDs using dvdauthor? I've been attempting to create graphical buttons for a DVD, and I've followed the instructions in various places like:

http://www.linuxjournal.com/node/6953/print and
http://www.tappin.me.uk/Linux/dvd.html

but I'm getting a weird error with spumux. Here's the spumux xml file:

<subpictures>
<stream>
<spu
force="yes"
start="00:00:00.00"
image="WeddingMain.png"
highlight="WeddingHilight.png"
autooutline="infer"
outlinewidth="6"
autoorder="rows">
</spu>
</stream>
</subpictures>

The png files for the image and highlight attributes are indexed with 4 colors, as recommended. However, when I attempt to use spumux with:

mplex -f 8 -o /dev/stdout weddingvideo.m2v alison.mp2 | spumux -v 2 weddingvideo.xml > weddingvideo.mpg

I get the following result from spumux:

INFO: PNG had 4 colors
INFO: PNG had 4 colors
INFO: Constructing blank sel
INFO: Autodetect 0 = 85x367-298x434
INFO: Autodetect 1 = 434x368-647x435
INFO: Pickbuttongroups, success with 1 groups, useimg=0
spumux: subgen-image.c:726: imgfix: Assertion `useimg' failed.
Aborted

Does anyone have any idea why this would happen?
