Let me chime in to save others (most of all: the devs) the time to
answer here. I'm not very knowledgeable on the matter, but I believe
everything has been said already. The Quicktime framework called QTKit
exists only as 32-bit version and has been deprecated. Since Mac OS X
Lion the new default media framework is AVFoundation  which is 64-
bit, which is the 'primary' arch on OS X / macOS. From what I
understand, Gem only has plugins for QTKit, but not yet for
AVFoundation (we read recently that Dan has been working on video
playback with AVFoundation, though). This means if you want to have
video playback and recording in Gem now, you are bound to 32-bit Gem,
which means you need a 32-bit Pd and all other externals you want to
use have to be 32-bit, too. At some point, Apple will stop including
old QTKit in their newer OS versions and Gem will lose most (any?)
ability to access/write media (camera, video files, etc.).
It takes some work to make Gem support the newer AVFoundation
framework, but this step is necessary for 64-bit / future-proof Gem to
become a reality.
Please correct me if I spread alternative facts.
