If the forwarded streams of a call are later combined without the inserted
silence, the resulting mix may end up with them out of sync. This
is already handled when outputting mixed files so the same functionality
from mix.c has been added for tls forwarding
Pandoc is available even on stretch, and unlike ronn is
actively maintained.
Fix -- markdown escaping.
Use __x__ for bold, and *x* for italics.
Remove .8.ronn symlinks.

For a compatibility reasons (with other doc files and with RTD)
the `rtpengine.pod` and `rtpengine-recording.pod` file get
converted to the Markdown syntax.
The compilation of MD syntax synopsis files will work
using `ronn` application, which converts them to man pages.

Use the address family of the address object to do the conversion, not
the family of the socket. This allows for v4-in-v6 socket usage.

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.

... as an extra offset for newly added sources, based on the difference
between the last runtime (read time) of the buffer and the current time.

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.

If the expected buffer to hold a packet was determined incorrectly, log
a warning instead of throwing an assertion.

Change-Id: I4169378a27b27fed51e453e6d2da8014259c659e
Prevent a wrongly advertised (too small) a=ptime from producing too
small buffers to hold encoded packets by flagging codecs with a fixed or
minimum frame size as such.
This is relevant to libavcodec only as the code determines the expected
frame size from the clock rate and the ptime.

This type is used as const everywhere except internally, so make it part

Instead of going through ffmpeg to en/decode Opus, use libopus directly,
which allows us to benefit from additional features that aren't
available when going through ffmpeg.

Some codecs (e.g. Opus) can natively encode audio with various clock
rates without producing an output that is locked to that clock rate and
without requiring resampling the input. Add an appropriate callback
function and adapt tests.

G.722 uses 4 bits per sample, not 8. This error was negated by the ptime
incorrectly being adjusted by the clock rate multiplier.

This makes it possible to have codecs running at variable clock rates
that differ from their RTP clock rates.

Instead of just having an integer multiplier, support a fractional
factor. This allows us to have the RTP clock rate run faster than the
audio clock rate, and not just slower by an integer factor.
