Do you actually have any QNX expierence?
This is the kind of stuff its meant for- its an OS that delievers deterministic maxamum latencies.. Thats qhy QNX is a real-time OS, and linux isn't. Whats this mean.. Well, a real-time OS isn't normally as efficient at processing mid-large level stuff (quiz: whats the best system for large large jobs? Batch processing.. its the most efficient.. but not to interactive...), however it gives you gaurentees that when you make a syscall, etc, it WILL happen in a certain amount of time.
If I'm making machinery go, and this machinery is responsible for something important, I'm sure as heck gonna make sure I use a real-time OS.
Linux is cool, yes.. been running it for a long long time, but RTlinux isn't nearly as mature as QNX...
I must say, from my experience programming on, and for QNX: its nice.
Well, I don't really care about watching movies.. I want access to the bitstream so that I can do image processing!
I've yet to find a well-documented video API under linux... makes developing certain (cool ) applications very very difficult! I've just been doing "raw" videos... Not very good for displaying due to I/O restrictions, and not very good for your HD, but gimme something better and I'll use it!
That being said, Sorenson compression seems to be the "cleanest" format out there (counting formats that do any decent compression), and I'm deeply saddened that its "protected" under US patent law.
The author of xanim had something about talking to apple about (not)letting him implement it a while back, but no go... apple won't let go.
