Review: python-opuslib-next 1.3.1-2

Package Information

Description	Python bindings for the Opus audio codec This library encodes PCM audio as Opus packets and decodes Opus packets back to PCM, with support for integer and floating-point samples. It provides encoder and decoder interfaces for single streams, multistream audio and projection-based channel mapping. Codec controls allow adjustment of bitrate, encoding complexity and in-band forward error correction. This is a maintained fork of opuslib, retaining its API under the distinct module name opuslib_next.

DFSG NEW review for python-opuslib-next version 1.3.1-2

Summary

Licensing is DFSG-compliant and debian/copyright is accurate: Yes
Packaging is of good quality: Yes
Issues: 0 blocker, 0 important, 0 minor
debian/watch: version 5
debian/copyright: machine-readable
Scan before the review: nothing found

Licensing

All upstream files are BSD-3-Clause, matching the single upstream LICENSE and the module docstring compile (':copyright: Copyright (c) 2025, Kalicyh', ':license: BSD 3-Clause License'). debian/copyright is DEP-5/machine-readable with the canonical Format URL; the Files: * catch-all covers every upstream file (only ~35 text files: opuslib_next/, tests/, benchmarks/, .github/, top-level docs) with holders Kalicyh 2025 and SvartalF 2012 (the retained opuslib heritage, explained in a Comment), and Files: debian/* for the packager. The full BSD-3-clause text is reproduced in a stand-alone License stanza, verbatim from upstream LICENSE, including its third-clause wording and the <COPYRIGHT HOLDER> placeholder that upstream and original opuslib carry. No non-free terms, binaries, minified files or files lacking a licence: the prescan author check found every holder named in debian/copyright.

Packaging

Standard, minimal dh-python packaging done right. debian/control has correct Build-Depends (debhelper-compat 14, dh-sequence-python3, dh-sequence-single-binary, pybuild-plugin-pyproject, python3-all, python3-hatchling) and Build-Depends-Indep for test-only deps (python3-pytest, libopus0, both <!nocheck>, consistent with compat 14 test-skipping). The runtime Depends: libopus0 is correct and necessary: the code does ctypes.CDLL('/usr/lib/x86_64-linux-gnu/libopus.so.0'), the real path of libopus.so.0 delivered by libopus0. python3-hatchling 1.30.1 in the archive satisfies the upstream hatchling>=1.27.0 build requirement. Standards-Version 4.7.4.1 equals current Policy 4.7.4.1; Vcs-*, Homepage, changelog (bug closure #1151105), source format 3.0 (quilt), docs file, salsa-ci.yml and upstream/metadata are all in order. rules is the one-line dh $@ --buildsystem=pybuild. No patches, maintainer scripts or hand-written tests/control needed (uses Testsuite: autopkgtest-pkg-pybuild).

Issues

None.

Verified ◂

Prescan 'copyright holders' item: the only holder found in source is 'Copyright (c) 2025, Kalicyh' (opuslib_next/init.py docstring), and it is named in the Files: * stanza; SvartalF (2012) is additionally listed in debian/copyright for the retained opuslib-derived code, matching the upstream LICENSE content that mentions 'SvartalF' in the third clause — no missing holder.
Complete recursive listing (gitignore:false, .pc and debian/ excluded) shows the entire source tree is 35+ text files: opuslib_next/, tests/, benchmarks/, .github/workflows/ and top-level LICENSE, README.md, pyproject.toml, uv.lock, .gitignore. Nothing built, minified, binary, or generated; no other LICENSE/COPYING/NOTICE/AUTHORS in any subdirectory.
debian/copyright License text is verbatim the upstream LICENSE (BSD-3-clause incl. <COPYRIGHT HOLDER> disclaimer placeholder and third clause) — accurate, full text present, so no /usr/share/common-licenses pointer needed.
grep across the tree for Copyright/©/SPDX/BSD/Redistribution/licence wording found licence notices only in LICENSE and opuslib_next/init.py; all other files are clean and covered by the Files: * stanza.
libopus0 exists in the archive and installs libopus.so.0 at exactly the paths opuslib_next/api/init.py loads (/usr/lib/x86_64-linux-gnu/libopus.so.0), so the unversioned Depends is right (verified via apt-cache).
python3-hatchling 1.30.1-2 in unstable satisfies pyproject's hatchling>=1.27.0 build requirement (verified via apt-cache); pybuild-plugin-pyproject exists.
Standards-Version 4.7.4.1 equals current Policy version 4.7.4.1 read from the policy tool; debhelper-compat 14; no substvar or nocheck concerns (Build-Depends-Indep python3-pytest and libopus0 both carry <!nocheck>).
uv.lock is a dev-only dependency lock file of package/URL records (no vendored code); it is not installed with the binary and has no licensing impact.
debian/watch, changelog and upstream/metadata reviewed only where they touch other findings; watch itself is outside this review's scope.
uscan found the packaged version as the newest upstream release (upstream 1.3.1, packaged 1.3.1).

Not confirmed ◂

Could not build or run the autopkgtest here; no cause for failure is visible from the tree (Build-Depends are satisfiable, libopus0 and python3-pytest are declared for the test run). This is a reported-only limitation.

Proposed changes ◂

None.
