It still contains html... ;)

This can be done, but you'd need a special "GUI" for this (like we
have a GUI for GTK, one for KDE, for Windows, ... and a special
NullGui). The rendering can be done using AGG, so the "FB" GUI (the
simplest one) would be a good start.

Unfortunately I haven't (and probably the other developers neither?)
the time to make this a priority (altough it has been requested a few
times), so Gnash won't offer this possibility in the near future.

Of course you're welcome to extend Gnash in this direction and send us
your patches. It should not be hard to do once you understand the GUI
concept and have the PNG writing code.

For the rest Gnash already has all necessary options for automating
SWF-to-whatever conversions:
  -1 switch exits instead of looping the movie
  -t exits after a specified amount of time

Good luck,
Udo
