*
|

* If socket connection is establised, a PH_PRIM_CTRL_REQ message with
|
||||
* PH_CTRL_ENABLE information is received by the socket server user.
|
||||
* If the socket connection is lost, a PH_PRIM_CTRL_REQ message with
|
||||
* PH_CTRL_DISABLE information is received by the user.
|
||||
*
|
||||
* If socket connection is establised, a PH_PRIM_CTRL_IND message with
|
||||
* PH_CTRL_ENABLE information is received by the socket client user.
|
||||
* If the socket connection is lost, a PH_PRIM_CTRL_IND message with
|
||||
* PH_CTRL_DISABLE information is received by the user.
|
||||
*
|
||||
* The socket server should enable or disable interface depending on
|
||||
* the PH_CTRL_ENABLE / PH_CTRL_DISABLE information.
|
||||
*
|
||||
* The socket client user shall keep track of last PH_PRIM_ACT_IND /
|
||||
* PH_PRIM_DEACT_IND message and treat a PH_PRIM_CTRL_IND message with
|
||||
* PH_CTRL_DISABLE information as a deactivation of all channels that
|
||||
* were activated. Also it shall reject every PH_RIM_ACT_REQ with a
|
||||
* PH_PRIM_DACT_IND, if the socket is currently unavailable.
|
||||
*
|
||||
* PH_PRIM_CTRL_REQ and PH_PRIM_CTRL_IND messages with PH_CTRL_ENABLE
|
||||
* and PH_CTRL_DISABLE informations are not assoicated with a channel
|
||||
* number. The socket sender shall set it to 0, the receiver shall
|
||||
* ignore it.
|
||||
*
|
||||
* A missing MODE in PH_PRIM_ACT_REQ is interepreted as default:
|
||||
* HDLC on D-channel, TRANS on B-channel.
|
||||
*
|
||||
* Each packet on the socket shall have the follwoing header:
|
||||
* uint8_t channel;
|
||||
* uint8_t prim;
|
||||
* uint16_t length;
|
||||
*
|
||||
* The length shall be in host's endian on UN sockets and in network
|
||||
* endian on TCP sockets and not being transmitted on UDP sockets.
|
||||
*
|
||||
* 0 to 65535 bytes shall follow the header, depending on the length
|
||||
* information field.

/* How does it work:
|
||||
*
|
||||
* Storing:
|
||||
*
|
||||
* Each saved frame is sorted into the list of packages by their sequence
|
||||
* number.
|
||||
*
|
||||
* The first packet will be stored with a delay of minimum jitter window size.
|
||||
*
|
||||
* Packets with the same sequence are dropped.
|
||||
*
|
||||
* Late packets cause jitter window to shift into the past (allowing more
|
||||
* delay). Minimum jitter window size is added also, to prevent subsequent
|
||||
* packets from beeing late too.
|
||||
*
|
||||
* Early packts that exceed maximum jitter window size cause jitter
|
||||
* window to shift into the future.
|
||||
*
|
||||
* If no sequence is provided (autosequence), the sequence number is generated
|
||||
* by a counter. Also the timestamp is generated by counting the length of each
|
||||
* frame.
|
||||
*
|
||||
* If ssrc changes, the buffer is reset.
|
||||
*
|
||||
*
|
||||
* Playout:
|
||||
*
|
||||
* The caller of the playout function can request any length of samples from
|
||||
* the packet list. The packt's time stamp and the jitter window time stamp
|
||||
* indicate what portion of a packet is already provided to the caller.
|
||||
* Complete packet, sent to the caller, are removed.
|
||||
*
|
||||
* Missing packets are interpolated by repeating last 20ms of audio (optional)
|
||||
* or by inserting zeroes (sample size > 1 byte) or by inserting 0xff (sample
|
||||
* size = 1).
|
||||
*
|
||||
* Optionally the constant delay will be measured continuously and lowered to
|
||||
* minimum window size. (adaptive jitter buffer window)
|
||||
*
|
||||
* Note that the delay is measured with time stamp of frame, no matter what
|
||||
* the length is. Length is an extra delay, but not considered here.
|
||||
*
|
||||
*
|
||||
* Unocking:
|
||||
*
|
||||
* If the buffer is created or reset, the buffer is locked, so no packets are
|
||||
* stored. When the playout routine is called, the buffer is unlocked. This
|
||||
* prevents from filling the buffer before playout is performed, which would
|
||||
* cause high delay.
|
||||
