In order to allow "level-asymmetry-allowed" we now handle a new "profile" field, which as the same semantics as the "profile" field in H.264 stream so that we can force payloaded stream to have the right format when using the `gst_sdp_media_get_caps_from_media` to set caps filter after the payloader. This allows a simple negotiation in standard RTP negotiation based on SDPs (like webrtc) for that particular case, closely respecting the specs.
