It's certainly possible, but probably not a very good idea.  There  
are a enough knowable things about a FLV frame that makes it possible  
to find one if you know you have a few.

It sure as hell wouldn't be anywhere near the simplest thing that  
could possibly work, and it would likely require a bunch more hits to  
the disk since you'd have to binary search for a timestamp.  Indexing  
on the other hand is trivial and it has very good performance  
characteristics, at a small cost of maintaining a little metadata  
somewhere or another.
