Since the generic flags parsing is done (from now on) directly
in the `parse_rtpp_flags()`, there is no need to keep a separate
bencode list object to store them, which was originally intended
to be used later for parsing in `call_ng_flags_flags()`,
but not the case anymore.

having injected events on the recv list can cause out of order TS
values which results in is_in_dtmf incorrectly returning NULL and
letting the transcoded PCM frames through.
It also doesn't make sense to add DTMF to the send list unless they're
actually being sent, so injected delayed or unblocked
Change-Id: I07e2a35e27142715a5257f199326b7a3d133e2a8
now that the returned last_event_ts is always that of the previous
DTMF, we can ensure that the next one isn't transmitted until that
time plus the required pause.
Like the num_samples calculation, the actual time needs to be
increased by 1 packets worth of samples so tha pause lasts the
full duration required
Change-Id: I6da1dd7cbcf49f7f0431a5123df2cdc382fe3dba
this function is used to determine if a pause is needed on a new
injected DTMF's start ts to ensure a gap between the events. However,
if an inject request comes in after the end of the previous event
but before it would have been offset due to pause, no pause is added
This change returns the ts value from dtmf_state if the queue is
empty as that will always be the ts of the last DTMF transmitted
Change-Id: I4f3cf5115d1a8e26c0ca1bc9570c46e29391e0d0
the num_samples was added to the start_pts, which is the first event
packet timestamp, which has already increased its ts by its event
duration. so, the total duration of events ends up being one packet
more than intended.
Change-Id: I423bb222a81c5bd78e570ff2026c72dd4dd1b100
Make sure we increase the output RTP sequence
number for each generated packet in the case
of packets that need to be duplicated or sent
repeatedly (DTMF end event)
Change-Id: Ia16ffefc0791d01575248ac5d8025eb30ccaec67
in some scenarios the start event ts can be before the *pts value, which
will result in a shortened DTMF event being transmitted than expected during
injection as the end event ts is calculated based on that initial dtmf start
value.
This change updates the end event ts by the amount the start ts was
behind, so that the resulting event has the right duration
Change-Id: Ia637d1e1c5d92de8b35317ec552c22eae23c0645
when DTMF is being transmitted using codec_output_rtp, the scheduled
time to send the packet is calculated using the timestamp difference
from the last transmitted applied on top of the realtime time the
last packet was sent. However, the timestamp is only updated on the
first event packet so a delay needs to be passed in to codec_output_rtp
to ensure the subsequent packets are scheduled based on the event
duration of the event packets

A fix for bullseye/buster and focal:

It's a useful function for parsing flags, which
we most probably will need in the future, but unsed now.
Change-Id: I3bed7b52e565a24f4ea8ee791a5872ad9cb06228
During the parsing of `rtpp_flags` use the
`call_ng_flags_flags()` directly instead of the
`bencode_list_add_str()`, hence reduce amount
of iterations required to parse generic flags.
Additionally:
`call_ng_flags_flags()` is made visible for usage
within external files.
`helper_arg` union has been moved to the header.
Change-Id: I34399a0d3940a1276feb1210e4421cbcdf656e9d
Is added by:
- explicit generic flag "directionl"; or
- if the "from-tag" flag is used
Introduce the `directional` flag for `sdp_ng_flags` struct.
In use by:
- `media_block_match1()`
Additionally:
add `IS_OP_DIRECTIONAL()` marco check.
Change-Id: Ifd56ea2ad8277d7dec136def1c028c5e2b680ff1
For the sake of proper processing for From/To tags,
we need to know which message type originated interaction
with the rtpengine (from behalf of kamailo module).
This can be of two types:
- request
- reply
This can also be re-used later, if there is a need
to detect whether that was a request or reply.
P.S.: opmode and message type shouldn't be confused,
it's not the same, since SDP offer can come in the request
as well as in the reply message (late offer/answer).
So the opmode reflects what exactly is being done in terms of
rtpengine operations, meanwhile the message type shows, which
message type originated this processing.
Change-Id: I8336175d3cfcf521418ac18b71cb4a6d5730705d
Synchronize the `enum call_opmode` with the
kamailio module list of operation modes, as well
as with the `enum ng_command`.
This allows to operate based on `call_opmode`
in a more specific way, for example for a proper
setting of From/To tags based on directional flag,
which in its turn is being set using `call_opmode`.
Additionally introduce a macro checker, which covers
all previously non-existent operation mode types
as OP_OTHER, for backwards compatibility in conditions.
Change-Id: Idf4b9d910b81ee24be51008996c3fd02d8336a38
Add support of rtpp_flags parsing for the daemon.
From now on, it's possible to parse option flags
on the daemon side instead of the kamailio module.
It's identical to what the module does, but the
difference is:
- module sends general call identification such as:
call-id, From/To tags, viabranch using bencode
- meanwhile all generic/non-generic option flags
are added to the `rtpp_flags` bencode member as str
- parsing of that is done as usually using the
`call_ng_main_flags()` / `call_ng_flags_flags()`
and additionally using new parser `parse_rtpp_flags()`
New file implementation and header introduced:
- control_ng_flags_parser.c
- control_ng_flags_parser.h
Otherwise no functional changes, and the parsing itself
remains working following the same algorithm.

If multiple pollers are in use, use a single poller per call instead of
assigning pollers round-robin to each socket used in the call.
Change-Id: Iec49bd9d2fbd75d947d6232bcccfdfe87c4c6d7c
The poller-per-thread feature was broken with a division by zero. Take
the opportunity to rework it and eliminate the poller_map object. Use a
simple array of pollers for media sockets, plus one global poller for
control sockets. In the regular case only one poller is created and
everything points to that poller. In the poller-per-thread case, one
poller per thread is created, plus one poller (also with its own single
thread) for control connections. All control sockets use the single
control poller, while all media sockets get assigned one poller from the
pool in a round-robin fashion.

Look up the first object in the tree to determine the needed sleep time.
But instead of leaving the object in the tree for the next (post-sleep)
iteration, which requires another tree lookup, remove it from the tree
and remember it, anticipating that nothing would get added into the tree
to be scheduled sooner. This saves us from having to do another tree
lookup for each timer that runs.
Adapt the scheduling function to be able to handle this and wake up the
thread sooner if necessary.
