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.
