Generally, I mean you don't really have a warranty that alive ever returns 
false until pf_deactivate() is called. You are making not always correct 
assumptions about the way decoders may be used. Simply put, a decoder relying 
on that to return from its pf_decode() is a buggy decoder.

I thought so too when I started VLC development. But a lot of users seem to 
notice. So I don't think so anymore.
