This isn't a codec matter but a container one. As long as your
container supports arbitrary timestamp increments you can do it with
whatever codec you like.

And before some people object: some nasty codecs like mpeg try to be
incestuously tied to a particular container and/or store framerate (or
timestamp) information in the codec stream, but a good container can
still overcome this just fine.
