Oh, I didn't realise that. And I guess from your other patch that
there is much confusion in the code base over this one.

Well, in that case I'll work on a way to propagate the -vcodec string
all the way through find_stream_info so that it can be used for the
decoder lookup. Then the probe codec and actual decoder will be the
same, which seems desirable.
