GEM on OSX and pdp on any platform do this.

I started doing 1920x1080 HD work using GEM on OSX in 2006 and never had
performance problems. I had the engineers who write Final Cut Pro tell me
that what I was doing was physically impossible with modern CPUs, yet it was
done.  At this point streaming raw video out of a 5D or P2 cam, recording it
to disk while manipulating the video using shaders is the baseline for
performance, not fantasy.
