Stream FEC-encoded data over simple UDP-protocol?

[Bert Douglas]

FEC is not needed for UDP.    The UDP service delivers a packet, or does
not.
UDP does not randomly flip some bits inside the packet.
To tolerate packet loss, only redundancy is needed.

If you really want FEC, I don't think you will find ready to use libraries.
FEC is used in spacecraft applications.
There is some really good free documentation here.

The old stuff is simpler and probably good enough.
There is some free source code available.

Some related topics:
-- Reed Solomon block coding, used in CDroms, to protect against scratches.
-- RAID, used for fault tolerant disk arrays.

Good luck,
Bert Douglas
