feat(codec): Phase 0 — swap audiopus → opusic-c + opusic-sys (libopus 1.5.2)

Browse Source 
Phase 0 of the DRED integration (docs/PRD-dred-integration.md). No behavior
change: inband FEC stays ON, no DRED, same bitrate, same quality. This
commit unblocks Phase 1+ by getting us onto libopus 1.5.2 where DRED lives.

Rationale for going straight to a custom DecoderHandle: opusic-c::Decoder's
inner *mut OpusDecoder pointer is pub(crate), so we cannot reach it for the
Phase 3 DRED reconstruction path. Running two parallel decoders (one for
audio, one for DRED) would drift because the DRED decoder wouldn't see
normal decode calls. Single unified DecoderHandle over raw opusic-sys is
the only correct architecture, so we build it in Phase 0 rather than
rewriting opus_dec.rs twice.

Changes:
- Cargo.toml (workspace + wzp-codec): remove audiopus 0.3.0-rc.0, add
  opusic-c 1.5.5 (bundled + dred features), opusic-sys 0.6.0 (bundled),
  bytemuck 1. Pinned exactly for reproducible libopus 1.5.2.
- opus_enc.rs: rewritten against opusic_c::Encoder. Argument order for
  Encoder::new swapped (Channels first). set_inband_fec(bool) now maps
  to InbandFec::Mode1 (the libopus 1.5 equivalent of 1.3's LBRR). encode
  uses bytemuck::cast_slice<i16,u16> at the &[u16] boundary.
- dred_ffi.rs (new): DecoderHandle wrapping *mut OpusDecoder directly via
  opusic-sys. Owns the allocation, frees on Drop. Exposes decode,
  decode_lost, and a pub(crate) as_raw_ptr() for the future Phase 3 DRED
  reconstruction. Send+Sync justified via &mut self access discipline.
- opus_dec.rs: rewritten as a thin AudioDecoder impl over DecoderHandle.
  Behavior identical to pre-swap.

Verification (Phase 0 acceptance gates):
- cargo check --workspace: clean (30 pre-existing warnings in jni_bridge.rs
  unrelated to this work; zero in changed files).
- cargo test -p wzp-codec: 53 tests pass (50 pre-swap + 6 new: 3 in
  dred_ffi.rs for DecoderHandle lifecycle, 3 in opus_enc.rs for version
  check and roundtrip).
- linked_libopus_is_1_5 test asserts opusic_c::version() contains "1.5" —
  hard signal that the swap landed correctly.

//! Raw opusic-sys FFI wrappers for libopus 1.5.2 decoder + DRED reconstruction.
//!
//! # Why this module exists
//!
//! We cannot use `opusic_c::Decoder` because its inner `*mut OpusDecoder`
//! pointer is `pub(crate)` — not reachable from outside the opusic-c crate.
//! Phase 3 of the DRED integration needs to hand that same pointer to
//! `opus_decoder_dred_decode`, and running two parallel decoders (one from
//! opusic-c for normal audio, another from opusic-sys for DRED) would cause
//! the DRED-only decoder's internal state to drift out of sync with the
//! audio stream because it would not see normal decode calls.
//!
//! The fix is to own the raw decoder ourselves and use the same handle for
//! both normal decode AND future DRED reconstruction. This module is the
//! single owner of `*mut OpusDecoder` in the WZP workspace.
//!
//! Phase 0 only exposes `DecoderHandle` (normal decode). Phase 3 will add
//! `DredDecoderHandle`, `DredState`, and the `DredReconstructor` trait
//! implementation alongside it in this same file.

# Change Log
An overview of changes:
## [0.2.0]
* Now requires `cmake`.
* Windows will build via `cmake` too.
* Windows pre-built binaries have been removed.
* Updated `bindgen` to version `0.58`.
## [0.1.8]
This release adds build support for FreeBSD.
## [0.1.7]
Add missing `opus`-folder.
## [0.1.6]
This release removes the `bindgen`-dependency from the default features.
Additionally, the `bindgen`-feature has been added in order to generate a new binding.
## [0.1.4 and 0.1.5]
v0.1.4:
This release fixes a problem where `audiopus_sys` could not find the
Opus folder.
v0.1.5:
Convert Unix-relevant files' EOLs from CRLF to LF inside the opus-folder.
### **Fix**
* Bundle the Opus project again.
* Added missing `cfg` on `find_via_pkg_config`.
## [0.1.3]
Fixes build-issues related to `pkg-config`.
## [0.1.2]
This release adds the ability to bypass `pkg-config`.
### **Added:**
* Ignore `pkg-config` when `LIBOPUS_NO_PKG` or `OPUS_NO_PKG` is set.
* Print the dynamic/static build cause via `cargo:info`.
* Add missing repository-link in `Cargo.toml`.
## [0.1.1]
### **Added:**
* Copy Opus' source to `OUT_DIR` before building to avoid modifying and generating files outside of `OUT_DIR`.
### **Fixed:**
* Convert Unix-relevant files' EOLs from `CRLF` to `LF` inside the `opus`-folder.
* Resolve unused import warnings when building with Unix.

# Contributing
Everyone is welcome to get involved, may it be a pull request, suggestion, bug
report, or a textual improvement! : )
The language applied in this repository is British English.
## Contributions
Contributions to `audiopus_sys` should be first discussed up via an issue and then
implemented via pull request.
Issues display development-plans or required brainstorming, feel free to ask,
suggest, and discuss!
The `master`-branch contains the latest release.
## Comments & Documentation Style
- Comments are placed the lines before the related code line, not on the same
line.
- Write full sentences in British English.
- `unsafe` must always be reasoned and their soundness must be proven via a
comment.
- Use Rust intra-doc-links paths to refer Rust items in documentation:
`[name](crate::module::struct::method)`.
- If code ends up difficult, try to simplify it, if unavoidable, explain code
with comments. Prefer explicit variable naming instead of abbreviations.
## Commit Style
Write full sentences in British English.
Commits should describe the action being peformed.
Example:
- *Fix deadlock for events.*
- *Correct grammar in `command`-example.*
## Pull Request Checklist
- Make sure to open an issue prior working on a problem or ask on existing
issue be assigned.
- If a pull requests breaks the current API, use the `breaking-changes`-branch,
otherwise `stable-changes`.
- Commits shall be as small as possible, compile, and pass all tests.
- Make sure your code is formatted with `rustfmt` and free of lints,
run `cargo fmt` and `cargo clippy`.
- If you fixed a bug, add a test for that bug. Unit tests belong inside the
same file's `mod` named `tests`, integrational tests belong inside the
`tests`-folder.
- Last but not least, make sure your planned pull request merges cleanly,
if it does not, rebase your changes.
If you have any questions left, please reach out via the issue system : )

# About
`audiopus_sys` is an FFI-Rust-binding to [`Opus`] version 1.3.
Orginally, this sys-crate was made to empower the [`serenity`]-crate to build audio features on Windows, Linux, and Mac. However, it's not limited to that.
Everyone is welcome to contribute,
check out the [`CONTRIBUTING.md`](CONTRIBUTING.md) for further guidance.
# Building
## Requirements
If you want to build Opus, you will need `cmake`.
If you have `pkg-config`, it will attempt to use that before building.
You can also link a pre-installed Opus, see [**Pre-installed Opus**](#Pre-installed-Opus)
below.
This crate provides a pre-built binding. In case you want to generate the
binding yourself, you will need [`Clang`](https://rust-lang.github.io/rust-bindgen/requirements.html#clang),
see [**Pre-installed Opus**](#Generating-The-Binding) below for further
instructions.
## Linking
`audiopus_sys` links to Opus 1.3 and supports Windows, Linux, and MacOS
By default, we statically link to Windows, MacOS, and if you use the
`musl`-environment. We will link dynamically for Linux except when using
mentioned `musl`.
This can be altered by compiling with the `static` or `dynamic` feature having
effects respective to their names. If both features are enabled,
we will pick your system's default.
Environment variables named `LIBOPUS_STATIC` or `OPUS_STATIC` will take
precedence over features thus overriding the behaviour. The value of these
environment variables have no influence of the result: If one of them is set,
statically linking will be picked.
## Pkg-Config
By default, `audiopus_sys` will use `pkg-config` on Unix or GNU.
Setting the environment variable `LIBOPUS_NO_PKG` or `OPUS_NO_PKG` will bypass
probing for Opus via `pkg-config`.
## Pre-installed Opus
If you have Opus pre-installed, you can set `LIBOPUS_LIB_DIR` or
`OPUS_LIB_DIR` to the directory containing Opus.
Be aware that using an Opus other than version 1.3 may not work.
# Generating The Binding
If you want to generate the binding yourself, you can use the
`generate_binding`-feature.
Be aware, `bindgen` requires Clang and its `LIBCLANG_PATH`
environment variable to be specified.
# Installation
Add this to your `Cargo.toml`:
```toml
[dependencies]
audiopus_sys = "0.2"
```

# WZP: distinguish real cl.exe from clang-cl. libopus uses `if(NOT MSVC)`
# to guard per-file `-msse4.1` / `-mssse3` / `-msse2` flags that GCC and
# clang (GNU driver) accept. Under clang-cl (Clang running in MSVC driver
# mode, as used by cargo-xwin cross-compiles), CMake sets MSVC=1 via
# Platform/Windows-MSVC.cmake, so those guards become false and the
# SIMD source files end up compiled WITHOUT the required target feature
# — which then explodes in silk/x86/NSQ_sse4_1.c with
# "always_inline function '_mm_cvtepi16_epi32' requires target feature
# 'sse4.1'" errors. clang-cl, unlike real cl.exe, still honors Clang's
# target-feature system, and accepts `-msse4.1` (LLVM 14+) to enable it.
#
# Split real cl.exe (which genuinely doesn't need per-feature gating
# because its SIMD intrinsic headers are unconditionally available) from
# clang-cl (which does need gating) using CMAKE_C_COMPILER_ID. Then the
# `if(NOT MSVC)` guards below become `if(NOT MSVC_CL)` so clang-cl gets
# the GCC-style per-file flags, and the `if(MSVC)` global /arch block at
# the bottom becomes `if(MSVC_CL)` so only real cl.exe applies `/arch:AVX`
# / `/arch:SSE2` globally (clang-cl relies on per-file `-msse` instead).

== Opus audio codec ==
Opus is a codec for interactive speech and audio transmission over the Internet.
Opus can handle a wide range of interactive audio applications, including
Voice over IP, videoconferencing, in-game chat, and even remote live music
performances. It can scale from low bit-rate narrowband speech to very high
quality stereo music.
Opus, when coupled with an appropriate container format, is also suitable
for non-realtime stored-file applications such as music distribution, game
soundtracks, portable music players, jukeboxes, and other applications that
have historically used high latency formats such as MP3, AAC, or Vorbis.
Opus is specified by IETF RFC 6716:
https://tools.ietf.org/html/rfc6716
The Opus format and this implementation of it are subject to the royalty-
free patent and copyright licenses specified in the file COPYING.
This package implements a shared library for encoding and decoding raw Opus
bitstreams. Raw Opus bitstreams should be used over RTP according to
https://tools.ietf.org/html/rfc7587
The package also includes a number of test tools used for testing the
correct operation of the library. The bitstreams read/written by these
tools should not be used for Opus file distribution: They include
additional debugging data and cannot support seeking.
Opus stored in files should use the Ogg encapsulation for Opus which is
described at:
https://tools.ietf.org/html/rfc7845
An opus-tools package is available which provides encoding and decoding of
Ogg encapsulated Opus files and includes a number of useful features.
Opus-tools can be found at:
https://gitlab.xiph.org/xiph/opus-tools.git
or on the main Opus website:
https://opus-codec.org/

% sudo apt-get install git autoconf automake libtool gcc make
On a Fedora/Redhat based Linux:
% sudo dnf install git autoconf automake libtool gcc make
Or for older Redhat/Centos Linux releases:
% sudo yum install git autoconf automake libtool gcc make
On Apple macOS, install Xcode and brew.sh, then in the Terminal enter:
% brew install autoconf automake libtool
1) Clone the repository:
% git clone https://gitlab.xiph.org/xiph/opus.git
% cd opus
2) Compiling the source
% ./autogen.sh
% ./configure
% make
3) Install the codec libraries (optional)
% sudo make install
Once you have compiled the codec, there will be a opus_demo executable
in the top directory.
Usage: opus_demo [-e] <application> <sampling rate (Hz)> <channels (1/2)>
<bits per second> [options] <input> <output>
opus_demo -d <sampling rate (Hz)> <channels (1/2)> [options]
<input> <output>
mode: voip | audio | restricted-lowdelay
options:
-e : only runs the encoder (output the bit-stream)
-d : only runs the decoder (reads the bit-stream as input)
-cbr : enable constant bitrate; default: variable bitrate
-cvbr : enable constrained variable bitrate; default:
unconstrained
-bandwidth <NB|MB|WB|SWB|FB>
: audio bandwidth (from narrowband to fullband);
default: sampling rate
-framesize <2.5|5|10|20|40|60>
: frame size in ms; default: 20
-max_payload <bytes>
: maximum payload size in bytes, default: 1024
-complexity <comp>
: complexity, 0 (lowest) ... 10 (highest); default: 10
-inbandfec : enable SILK inband FEC
-forcemono : force mono encoding, even for stereo input
-dtx : enable SILK DTX
-loss <perc> : simulate packet loss, in percent (0-100); default: 0
input and output are little-endian signed 16-bit PCM files or opus
bitstreams with simple opus_demo proprietary framing.
== Testing ==
This package includes a collection of automated unit and system tests
which SHOULD be run after compiling the package especially the first
time it is run on a new platform.
To run the integrated tests:
% make check
There is also collection of standard test vectors which are not
included in this package for size reasons but can be obtained from:
https://opus-codec.org/docs/opus_testvectors-rfc8251.tar.gz
To run compare the code to these test vectors:
% curl -OL https://opus-codec.org/docs/opus_testvectors-rfc8251.tar.gz
% tar -zxf opus_testvectors-rfc8251.tar.gz
% ./tests/run_vectors.sh ./ opus_newvectors 48000
== Portability notes ==
This implementation uses floating-point by default but can be compiled to
use only fixed-point arithmetic by setting --enable-fixed-point (if using
autoconf) or by defining the FIXED_POINT macro (if building manually).
The fixed point implementation has somewhat lower audio quality and is
slower on platforms with fast FPUs, it is normally only used in embedded
environments.
The implementation can be compiled with either a C89 or a C99 compiler.
While it does not rely on any _undefined behavior_ as defined by C89 or
C99, it relies on common _implementation-defined behavior_ for two's
complement architectures:
o Right shifts of negative values are consistent with two's
complement arithmetic, so that a>>b is equivalent to
floor(a/(2^b)),
o For conversion to a signed integer of N bits, the value is reduced
modulo 2^N to be within range of the type,
o The result of integer division of a negative value is truncated
towards zero, and
o The compiler provides a 64-bit integer type (a C99 requirement
which is supported by most C89 compilers).

To build this source code, simply type:
% make
If this does not work, or if you want to change the default configuration
(e.g., to compile for a fixed-point architecture), simply edit the options
in the Makefile.
An up-to-date implementation conforming to this standard is available in a
Git repository at https://gitlab.xiph.org/xiph/opus.git or on a website at:
https://opus-codec.org/
However, although that implementation is expected to remain conformant
with the standard, it is the code in this RFC that shall remain normative.
To build from the git repository instead of using this RFC, follow these
steps:
1) Clone the repository (latest implementation of this standard at the time
of publication)
% git clone https://gitlab.xiph.org/xiph/opus.git
% cd opus
2) Compile
% ./autogen.sh
% ./configure
% make
Once you have compiled the codec, there will be a opus_demo executable in
the top directory.
Usage: opus_demo [-e] <application> <sampling rate (Hz)> <channels (1/2)>
<bits per second> [options] <input> <output>
opus_demo -d <sampling rate (Hz)> <channels (1/2)> [options]
<input> <output>
mode: voip | audio | restricted-lowdelay
options:
-e : only runs the encoder (output the bit-stream)
-d : only runs the decoder (reads the bit-stream as input)
-cbr : enable constant bitrate; default: variable bitrate
-cvbr : enable constrained variable bitrate; default: unconstrained

/*Although derived separately, the pulse vector coding scheme is equivalent to
a Pyramid Vector Quantizer \cite{Fis86}.
Some additional notes about an early version appear at
https://people.xiph.org/~tterribe/notes/cwrs.html, but the codebook ordering
and the definitions of some terms have evolved since that was written.
The conversion from a pulse vector to an integer index (encoding) and back
(decoding) is governed by two related functions, V(N,K) and U(N,K).
V(N,K) = the number of combinations, with replacement, of N items, taken K
at a time, when a sign bit is added to each item taken at least once (i.e.,
the number of N-dimensional unit pulse vectors with K pulses).
One way to compute this is via
V(N,K) = K>0 ? sum(k=1...K,2**k*choose(N,k)*choose(K-1,k-1)) : 1,
where choose() is the binomial function.
A table of values for N<10 and K<10 looks like:
V[10][10] = {
{1, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{1, 2, 2, 2, 2, 2, 2, 2, 2, 2},
{1, 4, 8, 12, 16, 20, 24, 28, 32, 36},
{1, 6, 18, 38, 66, 102, 146, 198, 258, 326},
{1, 8, 32, 88, 192, 360, 608, 952, 1408, 1992},
{1, 10, 50, 170, 450, 1002, 1970, 3530, 5890, 9290},
{1, 12, 72, 292, 912, 2364, 5336, 10836, 20256, 35436},
{1, 14, 98, 462, 1666, 4942, 12642, 28814, 59906, 115598},
{1, 16, 128, 688, 2816, 9424, 27008, 68464, 157184, 332688},
{1, 18, 162, 978, 4482, 16722, 53154, 148626, 374274, 864146}
};
U(N,K) = the number of such combinations wherein N-1 objects are taken at
most K-1 at a time.
This is given by
U(N,K) = sum(k=0...K-1,V(N-1,k))
= K>0 ? (V(N-1,K-1) + V(N,K-1))/2 : 0.
The latter expression also makes clear that U(N,K) is half the number of such
combinations wherein the first object is taken at least once.
Although it may not be clear from either of these definitions, U(N,K) is the
natural function to work with when enumerating the pulse vector codebooks,
not V(N,K).
U(N,K) is not well-defined for N=0, but with the extension
U(0,K) = K>0 ? 0 : 1,
the function becomes symmetric: U(N,K) = U(K,N), with a similar table:
U[10][10] = {
{1, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 1, 1, 1, 1, 1, 1, 1, 1, 1},
{0, 1, 3, 5, 7, 9, 11, 13, 15, 17},
{0, 1, 5, 13, 25, 41, 61, 85, 113, 145},
{0, 1, 7, 25, 63, 129, 231, 377, 575, 833},
{0, 1, 9, 41, 129, 321, 681, 1289, 2241, 3649},
{0, 1, 11, 61, 231, 681, 1683, 3653, 7183, 13073},
{0, 1, 13, 85, 377, 1289, 3653, 8989, 19825, 40081},
{0, 1, 15, 113, 575, 2241, 7183, 19825, 48639, 108545},
{0, 1, 17, 145, 833, 3649, 13073, 40081, 108545, 265729}
};
With this extension, V(N,K) may be written in terms of U(N,K):
V(N,K) = U(N,K) + U(N,K+1)
for all N>=0, K>=0.
Thus U(N,K+1) represents the number of combinations where the first element
is positive or zero, and U(N,K) represents the number of combinations where
it is negative.
With a large enough table of U(N,K) values, we could write O(N) encoding
and O(min(N*log(K),N+K)) decoding routines, but such a table would be
prohibitively large for small embedded devices (K may be as large as 32767
for small N, and N may be as large as 200).
Both functions obey the same recurrence relation:
V(N,K) = V(N-1,K) + V(N,K-1) + V(N-1,K-1),
U(N,K) = U(N-1,K) + U(N,K-1) + U(N-1,K-1),
for all N>0, K>0, with different initial conditions at N=0 or K=0.
This allows us to construct a row of one of the tables above given the
previous row or the next row.
Thus we can derive O(NK) encoding and decoding routines with O(K) memory
using only addition and subtraction.
When encoding, we build up from the U(2,K) row and work our way forwards.
When decoding, we need to start at the U(N,K) row and work our way backwards,
which requires a means of computing U(N,K).
U(N,K) may be computed from two previous values with the same N:
U(N,K) = ((2*N-1)*U(N,K-1) - U(N,K-2))/(K-1) + U(N,K-2)
for all N>1, and since U(N,K) is symmetric, a similar relation holds for two
previous values with the same K:
U(N,K>1) = ((2*K-1)*U(N-1,K) - U(N-2,K))/(N-1) + U(N-2,K)
for all K>1.
This allows us to construct an arbitrary row of the U(N,K) table by starting
with the first two values, which are constants.
This saves roughly 2/3 the work in our O(NK) decoding routine, but costs O(K)
multiplications.
Similar relations can be derived for V(N,K), but are not used here.
For N>0 and K>0, U(N,K) and V(N,K) take on the form of an (N-1)-degree
polynomial for fixed N.
The first few are
U(1,K) = 1,
U(2,K) = 2*K-1,
U(3,K) = (2*K-2)*K+1,
U(4,K) = (((4*K-6)*K+8)*K-3)/3,
U(5,K) = ((((2*K-4)*K+10)*K-8)*K+3)/3,
and
V(1,K) = 2,
V(2,K) = 4*K,
V(3,K) = 4*K*K+2,
V(4,K) = 8*(K*K+2)*K/3,
V(5,K) = ((4*K*K+20)*K*K+6)/3,
for all K>0.
This allows us to derive O(N) encoding and O(N*log(K)) decoding routines for
small N (and indeed decoding is also O(N) for N<3).

/*A range decoder.
This is an entropy decoder based upon \cite{Mar79}, which is itself a
rediscovery of the FIFO arithmetic code introduced by \cite{Pas76}.
It is very similar to arithmetic encoding, except that encoding is done with
digits in any base, instead of with bits, and so it is faster when using
larger bases (i.e.: a byte).
The author claims an average waste of $\frac{1}{2}\log_b(2b)$ bits, where $b$
is the base, longer than the theoretical optimum, but to my knowledge there
is no published justification for this claim.
This only seems true when using near-infinite precision arithmetic so that
the process is carried out with no rounding errors.
An excellent description of implementation details is available at
http://www.arturocampos.com/ac_range.html
A recent work \cite{MNW98} which proposes several changes to arithmetic
encoding for efficiency actually re-discovers many of the principles
behind range encoding, and presents a good theoretical analysis of them.
End of stream is handled by writing out the smallest number of bits that
ensures that the stream will be correctly decoded regardless of the value of
any subsequent bits.
ec_tell() can be used to determine how many bits were needed to decode
all the symbols thus far; other data can be packed in the remaining bits of
the input buffer.

/*============================================================================
** On Intel Pentium processors (especially PIII and probably P4), converting
** from float to int is very slow. To meet the C specs, the code produced by
** most C compilers targeting Pentium needs to change the FPU rounding mode
** before the float to int conversion is performed.
**
** Changing the FPU rounding mode causes the FPU pipeline to be flushed. It
** is this flushing of the pipeline which is so slow.
**
** Fortunately the ISO C99 specifications define the functions lrint, lrintf,
** llrint and llrintf which fix this problem as a side effect.
**
** On Unix-like systems, the configure process should have detected the
** presence of these functions. If they weren't found we have to replace them
** here with a standard C cast.

This replaces the Vorbis FFT (and uses the exact same API), which
was a bit too messy and that was ending up duplicating code

The algorithm is similar to (and inspired from) Fabrice Bellard's

/* This is a simple MDCT implementation that uses a N/4 complex FFT
to do most of the work. It should be relatively straightforward to
plug in pretty much and FFT here.
This replaces the Vorbis FFT (and uses the exact same API), which
was a bit too messy and that was ending up duplicating code
(might as well use the same FFT everywhere).
The algorithm is similar to (and inspired from) Fabrice Bellard's
MDCT implementation in FFMPEG, but has differences in signs, ordering
and scaling in many places.

/* This is a simple MDCT implementation that uses a N/4 complex FFT
to do most of the work. It should be relatively straightforward to
plug in pretty much and FFT here.
This replaces the Vorbis FFT (and uses the exact same API), which
was a bit too messy and that was ending up duplicating code
(might as well use the same FFT everywhere).
The algorithm is similar to (and inspired from) Fabrice Bellard's
MDCT implementation in FFMPEG, but has differences in signs, ordering
and scaling in many places.
