Using moviemaker to render movie of a sketch using an OpenGL canvas, no
file is produced on Mac OSX (10.4.11). The same sketch functions correctly
under Windows. This has been observed on the 1.x releases of Processing
(earlier builds functioned correctly).

There is no error message, the sketch just doesn't run!

The bug is discussed here:

This is mentioned on the "known bugs" page:

Hmm. I can't see any known issues regarding this bug - and bug 882 seems to
be addressing video _capture_ rather than moviemaker _rendering_

Of course, I may be missing a subtlety here, apologies if so :-)

moviemaker is part of the video library--it affects all sketches that use
the video library plus opengl or some other libraries.

Also for what it's worth, I probably won't be fixing the bug because we're
planning to move to a new video library soon, since Apple has discontinued
QuickTime for Java. Sorry for the trouble, but the other bug also lists a
workaround that should get things going for you again.
