Hi leozhang,
Adding dynamic resolution encoding support is the tendency, and there
are some previous discussions[1] [2]
about adding support for dynamic resolution encoding.
And one conclusion is that we'd prefer to cope with this in a more
general way, like recreating the
encoder instance instead of modifying in specific codec.

The problem is, that specially in the case of nvenc, re-creating the
encoder can take several seconds.
Patch generally looks okay to me, and I'm fine with applying it.
