In some cases, in particular when multiple input codecs are transcoding
to the same output codec (e.g. audio + DTMF -> audio), it's possible
that one of the input decoders produces frames in a format different
from the one expected by the encoder. Add an encoder-side resampler to
compensate for that.

ffmpeg 7.1+ has deprecated direct usage of ->sample_fmts in favour of a
call to avcodec_get_supported_config(). Update accordingly.

Consider errors from dlopen() or dlsym() as hard errors. Don't just log
an error message and continue startup. If we were instructed to load a
plugin, make sure that we could actually load it.

Some gcc targets report ifunc as a supported attribute, while at the
same time actually trying to build the object fails with "ifunc not
supported on this target". Be more prejudicial with ifunc usage.

(cherry picked from commit 80014423c3)
Introduce rtpe_has_cpu_flag() and associated enum to test for specific
CPU flags. Use singleton approach to do the CPUID only once.
Convert simd_float2int16_array() to float2int16_array() as an ifunc. The
resolver function uses rtpe_has_cpu_flag() to determine which
implementation to use.
If no SIMD implementation is available, use the linked evs_syn_output()
from the shared object as before, with an intermediate wrapper function,
which is needed as the dlopen() happens only after the
float2int16_array() is resolved.

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.

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
of the typedef for brevity.

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.
Change-Id: I125c897ee9cbdac29278be9b6451d82b48ff94c2
This makes it possible to have codecs running at variable clock rates
that differ from their RTP clock rates.
Change-Id: Ia2f5effb82eefe8c3028573ba0a6697da28473b1
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.

Parsing out the a=fmtp string has been left up to the codec init
function until now, with the values that resulted from the parsing being
stored only within the codec. Convert this to an explicit method to
parse the a=fmtp string, and introduce a dedicated struct to store the
resulting values.
Functionally this change is a no-op.

Starting with release 5.1, ffmpeg obsoletes the `channels` and
`channel_layout` fields, replacing them with a unified `ch_layout`
struct of type AVChannelLayout. Add wrapper defines into the
compile-time build-test headers fix_frame_channel_layout*.h to
accommodate both new and old versions.
