Then I really don't see the point of it, getting -ovc copy from
something like "completely broken" to "almost completely broken"
does not seem like it is worth any effort to me.
Some people may have a use for this, but I think they would be served
much better by a special application, that possibly also takes much more
codec-specific stuff into account.
