If we anticipate to add more metadata common to video and audio, we might want to introduce a RTCEncodedFrameMetata dictionary that audio and video metadata dictionaries would extend.
Let's think about this once this PR is done.

<dt>
<dfn>synchronizationSource</dfn> of type <span class="idlMemberType">unsigned long</span>
</dt>
<dd>
<p>
The synchronization source (ssrc) identifier is an unsigned integer value per [[RFC3550]]
used to identify the stream of RTP packets that the encoded frame object is describing.
</p>
</dd>
<dt>
<dfn>payloadType</dfn> of type <span class="idlMemberType">octet</span>
</dt>
<dd>
<p>
The payload type is an unsigned integer value in the range from 0 to 127 per [[RFC3550]]
that is used to describe the format of the RTP payload.
</p>
</dd>
<dt>
<dfn>contributingSources</dfn> of type <span class=
"idlMemberType">sequence&lt;unsigned long&gt;</span>
</dt>
<dd>
<p>
The list of contribution sources (csrc list) as defined in [[RFC3550]].
