My first reaction says that there is no reason that the MPEG decoder has
to send invalid data, even without the I frame.  For instance if you
working with an I-slice stream you may want to show just the intra-coded
sections of the P-frames, and just make the rest black.  So I would say
that it should be the decoder's responsibility to provide valid frames,
whether they be NULL (black) or something like that.
