What are the supported platforms of the new driver? Does your driver
support ZynqMP, too?
If there are enough similarities between the encoders, I'd happily
replace parts of the current driver with functionality of the upcoming
driver or reuse the infrastructure of the new driver.

Sorry, I don't understand what you mean by parsing and conversion. Do
you mean the mailbox messages or the NAL units?
Can you point me to some repository with your upcoming driver? I'd
really like to know what's coming up to have an informed discussion how
to structure the directory.
