Description
|
|
Packit |
8ff292 |
Payload encoded H.261 video frames into RTP packets according to RFC 4587.
|
|
Packit |
8ff292 |
For detailed information see: https://www.rfc-editor.org/rfc/rfc4587.txt
|
|
Packit |
8ff292 |
The payloader takes a H.261 frame, parses it and splits it into fragments
|
|
Packit |
8ff292 |
on MB boundaries in order to match configured MTU size. For each fragment
|
|
Packit |
8ff292 |
an RTP packet is constructed with an RTP packet header followed by the
|
|
Packit |
8ff292 |
fragment. In addition the payloader will make sure the packetized H.261
|
|
Packit |
8ff292 |
stream appears as a continuous bit-stream after depacketization by shifting
|
|
Packit |
8ff292 |
the encoded bit-stream of a frame to align with the last significant bit of
|
|
Packit |
8ff292 |
the previous frame. This helps interoperability in the case where the
|
|
Packit |
8ff292 |
encoder does not produce a continuous bit-stream but the decoder requires
|
|
Packit |
8ff292 |
it.
