still use 0.42.5 with no problems for me :)
Can the 32-bit QuickTime API work at all in 64-bit mode ? It could
explain some things... I remember that Apple designed some things as
if 64-bit would never happen, and then when was the time to support
64-bit mode, they came up with a new QuickTime interface that is
very much different and won't run on OSX-10.4.
As a result, a different GEM component would have to be written to
support the new QuickTime. Correct me if I'm wrong. No, two of them,
one for the movie files, one for the cameras.
I'm not saying that this is what prevents Gem from building at
all... I'm not talking about that kind of problem. But to get a full
64-bit release, much of QuickTime support code has to be rewritten.
AFAIK, Quicktime is dead at 32-bit, and there is a totally new API for
64-bit. Check gem-dev for more info, Chris Clepper has posted more
about it. But since gmerlin, gstreamer and other backends work on Mac
OS X and work in 64-bit, Gem could be build for 64-bit Mac OS X using
those. Then that would lose the highly optimized backend stuff in
Quicktime.
