| <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> |
