Freevo 1: Graphic OSD for TV

Right after giving up with attempting to use the logo
filters and other
hacks to get an OSD on the screen, I've started to look at
using a shaped
window.

Now my preference for X toolkits is PyGTK but I'm worried
this may place a
too large burden on those with small systems. I've looked at
(and got a
very simple example working) python-xlib, but it is not
complete and
specifically doesn't appear to free pixmaps.

FLTK doesn't support shaped windows in version 1 and the
version 2
bindings are only beta.

Qt - I haven't looked at, but this probably has the same
issues as PyGTK
(ie size).

TK - Is slow and horrid, but there is support for shaped
windows via an
extension

Does any one know of any other lightweight toolkits with
python bindings
that does shaped windows?

Finally, if not, then is it asking too much of our users to
install PyGTK
or compile a small X application?

Any thoughts?

Cheers

Adam

Please note I have tried using most of the features provided
by the
current players and they simple don't fit the bill. Either
they require a
patch that isn't mainline yet or they don't work as
expected. Also the
majority of the OSD are applied to the video before it is
scaled meaning
that you get a small squished OSD when viewing a widescreen
video on a 4:3
display.
The only thing that is lost using a shaped window is alpha
compositing
over the video which is not a big thing.

Will your work only be for the 2.x branch then?

Bad form I know to answer one's own post, but after a
"well why don't I
see what this kaa.display thing is" I realised that
with a small patch it
will do exactly what I need. Should have started looking a
bit closer to
home first.

No as long as people don't mind installing kaa.display it
will work on
the 1.8 branch, that's my intention.
