What RFC describes the FEC packetisation for WebRTC

[roxlu]

Hi, 

I've been reading up on FEC and I want to implement a FEC method in my C/C++ WebRTC library to experiment

with different ways to handle packet loss.  Some people pointed me to RFC5109 and although the introduction

talks about a generic solution for different FEC methods, most of the RFC describes a solution for XOR based

FEC.  Also nobody, including me, has been able to give a conclusive answer if e.g. Reed Solomon can be

used together with the packetisation in RFC5109.

I've also found this presentation by Giri Mandyam who refers to RFC6363 and RFC6364. I've not yet read

RFC6363, but from a first look at it, this also seems like a generic solution for create RTP packets with

FEC.   I've also found about 5 other RFCs which describe the RTP payload formats for specific FEC schemes,

e.g. like this one that describes Reed Solomon for RTP.

Can someone clarify if there is a generic RTP format that can be used with different FEC schemes and if 

this format can be used with WebRTC? 

Thanks

Several of us are working on a FEC document for WebRTC. Expect to see this in the next week or so.

Any progress on this document?  I'd be interested in seeing that; particularly any sections pertaining to RFC 2198 for RED stuff.
