<p>Extract encoded H.261 video frames from RTP packets according to RFC 4587.
For detailed information see: https://www.rfc-editor.org/rfc/rfc4587.txt</p>
<p>The depayloader takes an RTP packet and extracts its H.261 stream. It
aggregates the extracted stream until a complete frame is received before
it pushes it downstream.</p>
