Video issues during packet loss

Hi,

When there is moderate packet loss in the network connection between the browser and the video bridge I can see that video is freezing for a short period of time(frames not being rendered from time to time). I have also noticed that the current jicofo/videobridge is not using ulpfec/red in SDP. I looked at jicofo source code I saw this in git log:

commit a752ad938b12641e608297fd607ad5ea225d1540

Removes FEC and RED from the offer.

Is there a way to fix this issue or a plan to add ULPFEC/RED support?
