Do you use SDP munging (i.e. modification of the SDP between createOffer/createAnswer and setLocalDescription) to...

simulcast
simulcast (sdp munging gives me SSRCs)
VP9 SVC
stereo playout
changing header extensions
changing codecs preferences
changing rtp payload types
changing ssrcs
restricting bandwidth
turning off layers
enabling codecs not available by default
something else (please specify)

(feel free to edit and amend this list)

It might be good to ask people do separate their answers for certain browsers even though I suspect a lot of this is chrome/libwebrtc specific.

Some other minor things I think i have done in the past munging SDPs:

change audio packetization time
change audio bitrate
enable dtx
It can be summarized as "opus configuration" :)
