            Bug ID: 795939
           Summary: webrtcbin: Lack of mandatory fields in offer SDP in
                    case of h.264 stream
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: All
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: ilya.smelykh at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

When webrtcbin forms sdp for an offer it doesn't add such params as
packetization-mode, profile-level-id, etc.

It's seems like since Google Chrome updated to version 66 at least
packetization-mode parameter is required and Chrome fails to create an answer
when this param not presented in SDP for remote description. 

Modifying offer's sdp in js by adding packetization-mode=1 makes video working
in Chrome 66.
