[visionegg] Re: quicktime

From Apple's website I downloaded Quicktime 7.3 SDK for Windows, and
QTMLClient.dll wasn't in the download.

From googling QTMLClient.dll it seems like it may have been included in
earlier versions (e.g. Quicktime 5 SDK).  I found a couple different
places where I could download different versions of QTMLClient.dll.  For
both versions, I placed it in the path where VisionEgg was trying to
find it, ran quicktime.py, and got the following error:

2008-04-15 19:50:33,980 (3160) CRITICAL: Traceback (most recent call
last):

    import VisionEgg.qtmovie as qtmovie

  File "C:\Python25\lib\ctypes\__init__.py", line 362, in __getattr__
    func = self.__getitem__(name)
  File "C:\Python25\lib\ctypes\__init__.py", line 367, in __getitem__
    func = self._FuncPtr((name_or_ordinal, self))
AttributeError: function 'NewMovieFromProperties' not found

Perhaps both the versions of QTMLClient.dll that I found are different
from yours?

Hi Mason,

I'll have to re-trace my steps w.r.t the Windows installation of 
QuickTime and see where those files came from. My guess is that if 
they're not with Apple's QuickTime download, they must be with the 
QuickTime SDK. Anyhow, I've been quite busy lately (sorry for the delay 
responding) and it will most likely be another few days before I can get

to this. I suspect that downloading and installing the SDK will 
hopefully solve the problem. Clearly this is something I need to sort 
out before the 1.1 release, so thanks for testing.
