/**
 * element-webrtcsrc:
 *
 * `webrtcsrc` is the source counterpart of the #webrtcsink element and can be
 * used to receive streams from it, it can also be used to easily playback WebRTC
 * streams coming from a web browser.
 *
 * To try the element, you should run #webrtcsink as described in its documentation,
 * finding its `peer-id` (in the signalling server logs for example) and then
 * run:
 *
 * ``` bash
 * gst-launch-1.0 webrtcsrc signaller::producer-peer-id=<webrtcsink-peer-id> ! videoconvert ! autovideosink
 * ```
 *
 * or directly using `playbin`:
 *
 * ``` bash
 * gst-launch-1.0 playbin3 uri="gstwebrtc://localhost:8443?peer-id=<webrtcsink-peer-id>"
 * ```
 *
 * ## Decoding
 *
 * To be able to precisely negotiate the WebRTC SDP, `webrtcsrc` is able to decode streams.
 * During SDP negotiation we expose our pads based on the peer offer and right after query caps
 * to see what downstream supports.
 * In practice in `uridecodebinX` or `playbinX`, decoding will happen
 * in `decodebinX` but for the case where a `videoconvert` is placed after a `video_XX` pad,
 * decoding will happen inside `webrtcsrc`.
 *
 * Since: 0.10
