I doubt they do that without building an index in the first place.

No, they need to queue _enough_ frames, and for that timestamps are
enough.

Encoding mostly does not care about rate.

Why would it be a problem?

Please be more specific.

I see no reason not to. But I also see no reason users should do it, and
you have not convinced me.

> I have yet to see anyone use timestamps wrong.

I suggest you spend a little time doing support on the users
mailing-list and you will see plenty.

You need to learn about the difference between accuracy and precision.
