You don't have to store them all, especially if you implement a strategy to 
start decoding frames you don't have once you start stepping back near the 
beginning of the ones you do. And anyway, 300MB of RAM is not entirely 
unreasonable. I presume the amount it used would be configurable.

I wonder how Quicktime does it. Possibly it avoids the issue simply by not 
supporting very long GOPs.
