Cool. The answer depends on which layer you intend to put error 

Some FEC protects against the corruption some bits within a datagram (or 
on permanent storage), while I think others are meant to recover 
entirely lost frames (whatever that means).

Depending on that, if I understand the FEC concept, it could presumably 
be done in a:
  (client-side)   (server-side)
- access plugin & access output plugin, e.g. RTP)
- demux plugin  & mux plugin, e.g. MPEG-TS)
-          codec plugins, e.g. H264)
