Log message:
Update to 1.3.1

Changelog:
Apr 12, 2019
This Opus 1.3.1 minor release fixes an issue with the analysis on
files with digital silence (all zeros), especially on x87 builds
(mostly affects 32-bit builds). It also includes two new features:

    A new OPUS_GET_IN_DTX query to know if the encoder is in DTX
    mode (last frame was either a comfort noise frame or not encoded
    at all)

    A new (and still experimental) CMake-based build system that
    is eventually meant to replace the VS2015 build system (the
    autotools one will stay).

Log message:
Updated libopus to 1.2.1.

1.2.1

This Opus 1.2.1 minor release fixes a relatively rare issue where
the 1.2 encoder would wrongly assume a signal to be bandlimited to
12 kHz and not encode frequencies between 12 and 20 kHz. This only
happens on a few clips, but it is good to update to avoid a potential
loss of quality.

1.2.

This Opus 1.2 major release brings many quality improvements, new
features, and bug fixes. You can read all the details in this release
demo page. Changes since 1.1.x include:

    Speech quality improvements especially in the 12-20 kbit/s range
    Improved VBR encoding for hybrid mode
    More aggressive use of wider speech bandwidth, including fullband speech \ 
starting at 14 kbit/s
    Music quality improvements in the 32-48 kb/s range
    Generic and SSE CELT optimizations
    Support for directly encoding packets up to 120 ms
    DTX support for CELT mode
    SILK CBR improvements
    Support for all of the fixes in draft-ietf-codec-opus-update-06 (the mono \ 
downmix and the folding fixes need --enable-update-draft)
    Many bug fixes, including integer wrap-arounds discovered through fuzzing \ 
(no security implications)

Log message:
Updated libopus to 1.1.5.

This Opus 1.1.5 release backports the surround encoder bug fix from
1.2-beta. There are no other changes compared to 1.1.4.

Log message:
don't fail the build just because we don't know how to check for cpu
features on ARM. it doesn't seem to be a problem if /cpu/procinfo is
empty as in netbsd/arm nor if procfs is unmounted.

Log message:
Enable Ambisonics support. Bump PKGREVISION
Requested by Jesus Cea.

Log message:
Updated libopus to 1.1.4.

This Opus 1.1.4 release fixes a single bug. A specially-crafted
Opus packet could cause an integer wrap-around in the SILK LSF
stabilization code. This would cause an out-of-bounds read 256
bytes before a constant table. In most circumstances, the consequences
are harmless and the result is simply noise in the audio.

This was reported as CVE-2017-0381. Contrary to that report, our
own analysis shows that no remote code execution is possible.
However, we are making this release as a precaution.

Log message:
Updated libopus to 1.1.3.

This Opus 1.1.3 release focuses mainly on optimizations and bug
fixes. Changes include:

* Neon optimizations improving performance on ARMv7 and ARMv8 by up to 15%
* Fixes some issues with 16-bit platforms (e.g. TI C55x)
* Fixes to comfort noise generation (CNG)
* Documenting that PLC packets can also be 2 bytes
* Includes experimental ambisonics work (--enable-ambisonics)

Log message:
Update libopus to 1.1.2:

Opus 1.1.2 includes:

    Fixes encoder or decoder state reset, which would previously
    disable some run-time selected architecture-specific optimizations;
    and
    Fixes hybrid mode discontinuous transmission (DTX) operation,
    where the comfort noise above 8 kHz was incorrectly estimated
    and could oscillate in time.

None of these bugs were regressions over previous releases.

Log message:
Update libopus to 1.1.1:

This Opus 1.1.1 release brings many optimizations to the encoder
and decoder, including:

*   x86 SSE, SSE2 and SSE4.1 intrinsics optimizations with run-time
    CPU detection contributed by Cisco Systems,
*   MIPS intrinsics optimizations contributed by Imagination
    Technologies,
*   ARM Neon optimizations contributed by Linaro and ARM,
*   many architecture-independent optimizations and memory footprint
    reductions that should improve performance on all platforms,
    and
*   several minor bug fixes.

The quality of the encoder should be mostly unchanged compared to
version 1.1.
