Dear John,
Whoops, it looks like I changed the quicktime.py demo slightly for use
with the "bleeding edge". I attach the full thing with this email, but
the new code looks like this:
bounds = movie.GetMovieBox()
height = bounds.bottom-bounds.top
width = bounds.right-bounds.left
Sorry about the confusion on this...

Adam Naples just directed me to a ctypes download that solved that
problem
(http://downloads.sourceforge.net/ctypes/ctypes-1.0.1.win32-py2.4.exe).
Thanks Adam!
Now, when quicktime.py runs, I get the visionegg intro window, but
when I click OK on this, I get the following error. Any ideas on
this one?
Thanks very much for continuing to help me along with this!
John

Thanks Andrew, good catch... I uninstalled VisionEgg, reinstalled
the bleeding edge version, ran quicktime.py, and got a different
error message indicating something about a module called ctypes. I
couldn't find any python files with this name anywhere. I also
confirmed that I had pyOpenGL installed. Any thoughts about how to
fix this error?
Thanks!

Are you sure it's exactly the same error? The error you post below
indicates line 18 of QuickTime.py is "import VisionEgg.gl_qt".
However, that's not the line 18 in the "bleeding edge" release. If
you post your new traceback, we can help you further...

Hi John,
I know this works on more machines than my own, so I suspect
there might be something wrong with your installation. Can you
delete the contents of C:\Python24\lib\site-packages\VisionEgg\
and then re-install with the new bleeding edge version and try
again?

Hi Andrew,
Thank you very much for getting back to me. I downloaded the
bleeding edge version (the output reads Vision Egg 1.1.dev), and
I'm still getting the same error... let me know if there's other
stuff I should try.
Cheers - John

Dear John,
On Windows, the quicktime stuff works in the "bleeding edge"
release. I will make an "official" release once I ensure that
quicktime is working in both Windows and Mac. (I'm afraid the
process of getting it working in Windows broke it on Mac, but
now that I actually have a decent Mac machine, I'm much less
averse to doing development for it.)
So, give the bleeding edge release a try and let us know if
there are any issues.

I am a newbie to visionegg and python who has just installed
them (and their dependencies) on my Windows XP machine. I'm
able to run most of the demos (in the visionegg-1.0-demos
package), except for some related to presenting video. It
looks like errors related to pygame.movie have been documented
on the listserv, but I'm having a problem running quicktime.py
as well. When I run it, I get the following error:

Although the message seems to point pretty clearly to a single
line in the gl_qt.py file that tries to load a module named
_gl_qt (and fails), I was unable to fix it... has anyone
encountered this problem, and if so, what is the solution?
Thanks!
