How do we know that we can just put the packets of the new instance
after the packets of the old instance and it will work?

It will work for image codecs, of course.

It will not work for raw video codecs, since the frame size and
characteristics are global.

It may work for some codecs.

It may work if we generate side data to renew the extra data.

Clearly, making a new encoder instance is not an universal solution.
