--- Comment #18 from Nicolas Dufresne (ndufresne) <nicolas at ndufresne.ca> ---
Right now we get these error because we no longer send NULL pointers to the
accelerator to avoid undefined behaviour. That's the lack of concealment, which
would require a reliable way to clone a close-by image or to create grey
initialized images in case there is none (like this case). That being said,
this is a lot of work, and I won't adventure that way.

I've suggested this way, because I do think it's important to trace these
errors, but I see no use of sending a pipeline error (even when not live). All
it will do is make a bad situation worst.

So I would says if this isn't the way, then we should go for 1 and drop these
macro, just like avdec.
