movie playback in oF darker than QT and uses lots of CPU

Given the same movie, in window 1 played through oF (ofVideoPlayer.load() and .play()), and in window 2 played through Quicktime Player 10.0, I’m seeing that the video played in oF is noticeably darker than the QT player. I’ve attached a file showing the difference. On the left is oF, on the right is QT.

I’ve also noticed that oF uses 162% CPU to do the same task that QT needs 16% CPU for.

Any ideas on what’s going on with the color or the CPU? Should I be using some other video library?

Oh, I should have probably mentioned:

I’m using the latest build from GitHub
I’m on a Snow Leopard 10.6.6 MBP
I’m using Xcode 4
The movie is a 720p H.264, 24fps video file.
