example code for ULP-FEC?

[Pascal Massimino]

Hi!

is there any sample (javascript, client-side in Chrome) on how to use ulpfec with H264 video? I couldn't find one in this page.

My situation: I'm streaming h264 as RTP packets over UDP to a reflector that transmits the packets to WebRTC client in Chrome (139.0.7258.139), thanks to a local HTTP server.

The packets with payload-type 96 (h264) and 125 (ULP-FEC) are sent to the PeerConnection, and the javascript client seems to be ok with them... but no error correction seems to be happening. I am surely missing something. 

So, any code pointer welcome!

thanks a lot,

skal/

ps: my sdp contains: a=rtpmap:125 ulpfec/90000

https://issues.chromium.org/issues/384844217 has some comments but in general flexfec is the way to go for H264 FEC
