Description from PR:
With the newer PNG library, spumux is detecting an errors about PNG
images being too big (at least on amd64). This patches uses a specific
libpng type for width and height.
devede was generating a DVD with a menu that was non-functional. It
took me awhile to narrow down the problem: spumux was skipping the
addition of a subtitle to the menu MPG file but not causing devede to
return an error. It seems that DVD's require a subtitle for the menu to
function even if it does not say anything.
Patch obtained from the dvdauthor repository:
