The SEI will be skipped by decoders that don't understand it, but available to those that do.

Thanks for your answer.The data is H.264 data with the OutFileMode set to 1 which means RTP not Annex. So in any case how much redundant bits could i add as a SEI message ? For example i divide the frame into 16 packets and add 2 more redundant packets for error recovery. Is it possible?

Isn't FEC usually done at the RTP level, though?

I need your kind suggestion on this too. I wonder not even a single code snippet i have seen which is applying FEC at any level so that newbies can get help from it. So if i want to add FEC at RTP level what would be your suggestion?
Apply Encode file using JM as RTP add FEC inside JM apply rtp_loss and Decode it?
or Take H.264 file as an input in matlab apply FEC pass it through noisy channel Recover packet loss and decode using JM?
Thanks
