This is currently unimplemented. Actually right now the error handlig
is so bad that we can crash on bad streams sometimes.

When we solve the crash problems error concealment can probably be
implemented outside of libmpeg2 - like you would get a list of slices
that were not properly decoded, and you'd have to do whatever you want
with these slices. Maybe we could try to also extract more information
like motion vectors from the slices above and below to help the error
concealment algorithms. But as I said we have nothing of that yet.

Are you interested in error concealment yourself ?

Of course I think I'm right. If I thought I was wrong, I'd change my mind.
