[Openmcl-devel] how to use quicktime

Just wondering if somebody has some ideas on how to use QuickTime from  
CCL (1.2). Here are some ways that do NOT work:

1) using QuickTime framework:

I can access the quicktime functions from PPC CCL

(ccl:open-shared-library "/System/Library/Frameworks/ 

using QT functions appears to work. But not so in Intel-Mac CCL

Error: Error opening shared library "/System/Library/Frameworks/ 
QuickTime.framework/QuickTime": dlopen(/System/Library/Frameworks/ 
QuickTime.framework/QuickTime, 10): no suitable image found. Did find:
 > /System/Library/Frameworks/QuickTime.framework/QuickTime: no  
matching architecture in universal wrapper

OK, I guess this not 64bit compatible.

2) using NS movie

ns:ns-movie is bound: #<OBJC:OBJC-CLASS NS:NS-MOVIE (#xA0894754)>

so I think this MAY work but I get the warning: Legacy Document,  
Important: This class is deprecated. Use QTMovie instead.

I rather not use this then.

3) using QTMovie

There is not obvious evidence of an existing class called QTMovie in  
CCL.... hmmm

4) using QTkit

(ccl:open-shared-library "/System/Library/Frameworks/QTKit.framework/ 

succeeds but how does one create the main classes, e.g., QTMovie and  
QTMovieView? I assume this would be the recommended route to go.

Has anybody managed to get some QuickTime code working?
