We don't know when libav managed to recover without a keyframe..

I can't see a good use case, the CORRUPTED flag seems enough for now. It's just
that intuitively there is a difference between corrupted and conceiled raw data
(mostly for audio, you would think corrupted data sounds like noise and
conceiled data is sortof close to the intended output)..
