* For detailed information see: https://www.rfc-editor.org/rfc/rfc4587.txt
*
* The payloader takes a H.261 frame, parses it and splits it into fragments
* on MB boundaries in order to match configured MTU size. For each fragment
* an RTP packet is constructed with an RTP packet header followed by the
* fragment. In addition the payloader will make sure the packetized H.261
* stream appears as a continuous bit-stream after depacketization by shifting
* the encoded bit-stream of a frame to align with the last significant bit of
* the previous frame. This helps interoperability in the case where the
* encoder does not produce a continuous bit-stream but the decoder requires
* it.
