Good point. I agree that deciding whether to do rot with each and
every frame and other function calls. Can this not be optimized?

I cannot decide, I am just commenting. I was just pointing out that
copying a large amount of code for few modifications makes the whole
thing ineffective and a large maintenance burden.

Michael Niedermayer is the flvdec maintainer, and other core developers
will also know better what to do.
