Do not proceed to the `g_hash_table_lookup()` if the `attr_name`
is empty.
Additonally: improve slightly the same check for the CMD_SUBST.

We don't necessarily have a parsed-out RTP header (e.g. when forwarding
T.38) so we can't use the RTP header values to keep stats. Use the
actual datagram size instead.

It substitutes a specified `a=` line taken from the concerned
media attributes list. If such line has been not found,
the attributes list remains untouched.
It subsitutes one attribute at a time, so one attribute into
another attribute.

dump_packet() had the "recording" argument removed at some point, making
the macro arguments invalid and checking for non-NULL pointless.

Since the function has been swapped to the 'bool' return value,
we must comply with it.

These tests depends on an additional feature ("end event") that hasn't

If the remote Opus decoder prefers receiving single-channel encoded
audio, honour it and send them single-channel audio.

This commit parses out the string, but doesn't do anything with the
values except for the FEC flag. Move the FEC on/off switch from the
extra codec options into the `fmtp` string.
Change-Id: I51f74f7cb62dd49a9af9815920f077bf300cfa33
In order to actually select codec options in the selection function, we
need to parse the `fmtp` string out first.

Track audio writes in the mix buffer to set the `active` flag to true
whenever a write occurs, which makes it possible to create the buffer in
an inactivate state and implicitly set it active on demand.
Handle the mix buffer not returning any data in the RTP sending logic
(which is what happens for an inactive buffer) by simply not sending any
packets.

Similar to the existing media_player, but instead of simply producing
its own standalone output media stream, the audio_player takes over the
entire media stream flowing to the receiver, including media forwarded
from the opposite side of the call, as well as media produced by the
media_player.

We use next_run.tv_sec as flag to signal shut down of the media player
timer. Don't even call the run function when the timer has already been
shut down.

A simple circular audio buffer that allows mixing multiple sources of
audio. Sources are tracked by SSRC and all sources are expected to
provide audio in the same format (same clock rate, channels, sample
format).
Only one consumer per buffer is supported, which is expected to retrieve
buffered audio at regular intervals (ptime) and so continuously empty
the buffer.
The first audio source to write into the buffer at the leading edge of
the circular buffer has its audio simply copied into the buffer, with
the leading edge advanced, while other later sources writing into the
buffer mixed into the existing buffered audio at their respective write
positions.

Convenience function to check whether any formats have changed, which

We have to restructure project's general README.md
in order to make all recently added documentation sources
(including RTD) be compliant and let it look centralized and
good organized.
The root of the repository still has the README.md, but
it only shows general summary on the project and then gives
links to the extended documentation sources:
- RTD stored
- GitHub stored

Deprecate `asserts/` as it's only used for keeping images now.
(github wiki links fixed accordingly)
Create `docs/images` to keep visual materials and to properly
link them from the RTD with markdown.

(cherry picked from commit 99e0d93650)
We have to unify the approach we use for setting these main blocks
of the documentation to let it: 1) be unified; 2) be compliant
with RTD.

This is a first commit introducing general readthedocs wiki
structure.
It introduced the following main chapters:
- Overview (is a symlink to the README.md), the readthedocs
parses the markdown from here and creates the overview page
- Architecture overview (with the sources taken from the git wiki)
- Unit-tests (with the sources taken from the git wiki)
- Troubleshooting Overview (now only memory leaks)
- Glossary (doesn't have much information for now)
