Applying a CIPerspectiveTransform to a QTMovieLayer

Hi,

I'm experimenting on 10.5.2 with applying CIFilters to QTMovieLayers. I have a simple test project that has a single NSView with a single QTMovieLayer. It applies a single filter to the QTMovieLayer, sets the default values on the filter, and that's it.

For most filters this works fine, but when I try to apply the CIPerspectiveTransform the console fills with messages of this nature:

CoreImage: ROI is not tilable: APPLY perspective DOD [118,140 528x367] ROI [183,219 19x22] RGBA_14 AFFINE [1 -0 -0 1 -16384 -16384] DOD [-16384,-16384 32768x32768] ROI [-13375,-8223 1712x2498] ARGB_8 IMAGE CIImage:0x7dae20 DOD [0,0 32768x32768] ARGB_8

This is, alas, the main filter I'm interested in using. What am I doing wrong?

Thanks,
Chris
