Maybe this is actually the same as what Andreas was asking, but could
you split this change into two - with the first part just doing the
renames, and then the second part adding the 4:2:2 handling. The fact
that the renames get mixed in with the conversions causes it to be hard
to keep track of what is actually new.
Thanks,
