Title:
[FFE] Merge 1.2.1-1 from Debian
Status in opus package in Ubuntu:
Invalid
Status in opus package in Debian:
Fix Released
Bug description:
Please merge 1.2.1-1 from Debian. I cannot work on this merge myself.
This is only a reference.
Opus 1.2.1 has been in Debian since October 2017 and no new bugs were
filed.
The current package version in Bionic 1.1.2 is the same as in Xenial.
It's a pity that the improvements in the new version will not be
present in the new LTS.
Looking at the upstream git log of opus [1], you'll see that there aren't
(relatively) many commits after 1.2.1 up to this day, which means that 1.2.1 is
a pretty stable release, and upstream goes directly to a major 1.3 release.

Version 1.2 brings improvements described here:

libopus 1.2.1
Jun 26, 2017
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.
There are no other changes compared to 1.2. Please report any
problems.
libopus 1.2
Jun 20, 2017
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)
There are no known regressions compared to the latest stable release
(1.1.5). Please report any problems.
libopus 1.2-rc1
Jun 8, 2017
Opus 1.2-rc1 is the first release candidate of the upcoming Opus 1.2
release. If no issues are found with it, it will soon become
1.2-final, so we encourage everyone to give it a try. Changes compared
to 1.2-beta include:
Improves quality on files with powerful tones that cause MDCT leakage
Improves bit allocation on mode transitions (CELT to/from SILK/hybrid)
More ARM Neon optimizations
Fixes to the speech/music detection at the very beginning of files
Fixes to the unit tests (fixes illegal instructions and –disable-static)
libopus 1.2-beta
May 24, 2017
This Opus 1.2-beta beta release of the upcoming Opus 1.2 fixes a bug in
surround encoding causing very bad quality on signals beyond a certain
amplitude. Thanks to Franziska Trojahn and others from HfT Leipzig for finding
this issue through their listening test (the quality of the two bad files in
the paper should now be similar to the others). Also included in this release
are some more ARM Neon optimizations and some low-bitrate quality tuning.
----------------------------------------------------------------
(In case of not approving on updating to 1.2.1 from the Release Team, I
suggest updating to the latest 1.1.x release, which is 1.1.5 [2], as it's a
bug-fix release)

Changelog from Debian:
opus (1.2.1-1) unstable; urgency=medium
* Fixes a bug in surround encoding causing very bad quality on loud signals
beyond a certain amplitude.
* Speech quality improvements especially in the 12-24 kbit/s range.
* Music quality improvements in the 32-48 kb/s range.
* More aggressive use of wider speech bandwidth, including fullband speech
starting at 14 kbit/s.
* Improved VBR encoding for hybrid mode.
* SILK CBR improvements.
* DTX support for CELT mode.
* Support for directly encoding packets up to 120 ms.
* Improves quality on files with powerful tones that cause MDCT leakage.
* Fixes for speech/music detection at the very beginning of files.
* Fixes an issue where the encoder can misdetect that the signal is SWB
instead of FB, lowpassing the signal.

opus (1.2~alpha2-1) unstable; urgency=medium
* Run the tonality analysis at 24 kHz, which reduces complexity while giving
better frequency resolution for the tonality estimate.
* 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.
* Ensure that NLSF cannot be negative when computing a min distance between
them. This was reported and fixed in July, and assessed as having only a
relatively minor impact (garbage output, from the garbage input needed to
trigger it), or at very worst, an assertion failure or simple crash from
a slightly out of bounds read. In December it was assigned CVE-2017-0381
by someone other than the upstream developers, with claims of it being a
'Critical' issue on Android, but we're yet to see any analysis to back
that up. Closes: #851612

opus (1.1.3-1) unstable; urgency=medium
* Remove the generation date from the docs to improve reproducible builds.
Closes: #825345
* Fixes some corner cases with the soft clipper.
* Improve CBR and some other issues seen with using crazy low rates.
* More robustness fixes for reporting bad input.
* More optimisations, mostly for ARM.
* More precision fixes for edge cases.
* Fixes to comfort noise generation.
