Log:
Workaround VDPAU decode errors on aspect change on NVidia.

The NVidia driver seems to expect a decoder reinit on aspect
change, otherwise giving a nonsense VDP_STATUS_INVALID_SIZE
error.
Since decode and display can run out of sync, we do not in fact
know when an aspect change will happen during decode but only when
we want to display that decoded frame, and with threaded decoding
these will differ significantly.
So just catch the error and retry decoding instead, this also has
the advantage of not affecting (and possibly costing performance)
drivers without this issue.
