license: relicense first-party code from GPL-2.0-or-later to Apache-2.0 
Owner sign-off: replace root LICENSE with Apache License 2.0, add a root
NOTICE file, and swap the GPL-2.0 boilerplate header in every first-party
core/ and obs-adapter/ source file for a short Apache-2.0 notice.

This resolves review finding C2 (GPLv2 top-level LICENSE vs. the vendored
Apache-2.0 LiveKit SDK is a license-compatibility violation): the whole
repo is now Apache-2.0, matching LiveKit, so there's no GPL/Apache clash
left. Updated the README Status gate and the CI workflow comment to reflect
that C2 is resolved, while leaving the C1 WebRTC/OpenH264 patent/royalty
gate untouched -- that question is still open and still blocks release.

third_party/ stays under its own upstream licenses; only this project's own
code changed hands. All 6 CTest suites still pass after the header swap.

LiveKit client-sdk-cpp redistribution notices

This plugin links and redistributes prebuilt binaries from livekit/client-sdk-cpp — the liblivekit / liblivekit_ffi shared libraries that ship next to the plugin module — so the SDK's licence and notice files ship with it.

LICENSE and NOTICE here are copied verbatim from the pinned release tag v1.10.1 (Apache License 2.0). They are staged into build/package/licenses/ by obs-adapter/CMakeLists.txt on every build, alongside this plugin's own Apache-2.0 LICENSE (this project's own first-party code was relicensed from GPL-2.0 to Apache-2.0 to match).

A correction to the design doc

The design doc's open questions say:

client-sdk-cpp's bundled LICENSE.md (~28 distinct third-party license blocks — Google WebRTC, OpenH264, etc.) must ship inside the plugin package

No such file exists at v1.10.1. Checked, on 2026-09-06:

  • The five release archives for this tag (livekit-sdk-<triple>-1.10.1.tar.gz / .zip) contain only include/, lib/, bin/ and share/livekit/build-info.json. No licence file of any kind.
  • The repository at tag v1.10.1 has LICENSE (Apache-2.0, 10142 bytes) and NOTICE (553 bytes) at its root. There is no LICENSE.md, no NOTICE.md, and no THIRD_PARTY_LICENSES file.

So what ships here is the Apache-2.0 licence and notice, which is what actually exists upstream. The aggregated third-party notice the design doc expected — covering the WebRTC/OpenH264/etc. code statically linked inside liblivekit_ffi.so — has not been located and is not being shipped. That is a real, open licensing question for whoever signs off on distributing release binaries, not something this packaging step has resolved. Worth raising upstream, or asking counsel whether the Apache-2.0 NOTICE alone suffices for a binary redistribution of that library.
