Decrypt SCTP-DTLS Traffic in WebRTC in Chrome

I'm trying to inspect the pakets sent over the sctp connection of webrtc datachannels in chrome on my local machine. There isnt really much information which I found about decrypting DTLS-Traffic (e.g. through wireshark). Is there a way to access the certificate generated for the peerconnection? If not, how would one decrypt the traffic by other means? (e.g. some mitm proxy, mostly those are for TLS only though).

the certificate alone won't help, Chrome typically uses DTLS with perfect forward secrecy.

The --disable-webrtc-encryption (see http://peter.sh/experiments/chromium-command-line-switches/) might work in canary.
