As discussed on IRC this should become a new event that describes the problem
(data corruption), not the solution (new keyframe).

This event would look very similar to the QoS event and would have also a
"type" or something kind of description that describes in what way things are
broken. We have to distinguish here between things like: reference frame
missing, some bits not as they should be, etc
Also we need to distinguish between "decoding not possible at all" and
"something could be decoded but might look awful".


Upstream could then decide to request a new keyframe, or lower the bitrate, or
do other things.
