Alex,
Yes I can confirm that the standard built in Video Input [on newest iMac aka
FaceTime HD Camera] will not work as a texture input to a GLSL Shader and that
, I believe, is directly related to the already bug reported problem with the
Video Input stock patch on Lion, to a Billboard that input will work first time
around, then if stopped and restarted , it will cause a hang or a crash I'm
told that is likely as not a machine specific issue with my edition of an iMac
[2009]. Similarly, when the video input is fed into the pretty plain, stock
GLSL Shader, it will not texture up the input. How nice to know one is not
alone on this •~

& all I get is blank empty space.
One interesting point whereby this GLS problem differs from the Video Input to
Billboard problem on Lion that I have already bug reported is that you can
fairly safely start and stop and get a consistent result - namely blank empty
space :-).
Not what this fellow's ordering , but I kind of find that oddly reassuring.
The start and restart problem with the Video Input patch to a Billboard in Lion
still results in a hang , often leading by means of intervention to a Force
Quit. Shall have to update the regression section.
BTW - slight side issue but has anyone else noticed that the online mailing
lists are [possibly temporarily] unavailable. and that OSDir has ceased at
archiving from 05/2011?

Peter Boocock
