ci: fix the three failures the first real three-platform run exposed
Linux, glibc. The LiveKit SDK's "linux-x64" asset is not actually generic:
it is built on Ubuntu 24.04 and needs GLIBC_2.38 and GLIBCXX_3.4.32, so
linking it on a 22.04 runner fails outright ("undefined reference to
std::ios_base_library_init()@GLIBCXX_3.4.32", "__isoc23_strtol@GLIBC_2.38").
That is exactly what happened when this repo's CI landed on the 22.04 Linux
runner instead of the 24.04 one. LiveKitSDK.cmake now defaults Linux to the
ubuntu-22.04 asset, which needs at most GLIBC_2.35 / GLIBCXX_3.4.30 (checked
with objdump against both archives) and therefore links and runs on 22.04 and
on everything newer -- the right floor for a plugin handed to directors as a
binary.
Linux, libobs version. The Linux job is pinned to ubuntu-24.04 rather than
ubuntu-latest, which this instance's two Linux runners answer with different
releases. 24.04's libobs-dev is 30.0.2 -- exactly the OBS version
buildspec.json pins for macOS/Windows -- so all three platforms build against
the same libobs. A 22.04 runner would have given OBS 27, a different API
surface.
macOS, no Xcode. The OBS sub-build failed its configure with "No
CMAKE_C_COMPILER could be found": the template hardcodes the Xcode generator,
and the `home-mac` runner has the Command Line Tools but no xcodebuild. The
sub-build now uses Ninja (with an explicit CMAKE_BUILD_TYPE, since Ninja is
single-config) and builds a single architecture rather than upstream's forced
universal -- this plugin is single-arch anyway, because client-sdk-cpp ships
single-arch dylibs, so a universal libobs would double the slowest step in CI
for a slice nothing links against.
While in there, generator flags are built as proper CMake lists so each
becomes its own argv entry. Upstream packs several into one space-separated
string and passes it unquoted, which execute_process hands to cmake as a
single argument; it happens not to matter for the optional flags upstream
passes, but it would silently swallow -DCMAKE_BUILD_TYPE.
Also lowers the libobs API floor in the adapter: video_format_get_parameters
instead of video_format_get_parameters_for_format. The _for_format variant
only exists from libobs 30 onwards and only differs for the 10-bit formats
(I010/P010) this source never receives, so using the older entry point keeps
the module loadable on an older OBS -- the direction that matters, since OBS
refuses modules built against a NEWER libobs than the one running.
Re-verified locally on Ubuntu 24.04 with the ubuntu-22.04 SDK asset:
ctest 6/6; the real-LiveKit integration test still reports "36 video frames,
323 audio frames, 10 state changes / 32 checks passed"; and the headless
libobs harness still logs "connected to ws://127.0.0.1:7880 ... watching
cam-test" followed by "video frame 640x360 I420" with the camera dropdown
populated from the live slot list.

ci: build the real OBS adapter on all three platforms
Two things: unbreak the Windows compile, and give macOS/Windows a libobs.
MSVC fix. test_json.cpp failed to compile on the Windows runner with
"a universal-character-name specifies an invalid character" and "illegal
escape sequence" -- MSVC still forms escape sequences and
universal-character-names INSIDE raw string literals, which it must not.
Every JSON input containing a backslash is now built by string concatenation
from a single kBS constant, which also sidesteps the separate murky corner of
translation phase 1 where a doubled backslash immediately followed by 'u' has
historically been treated inconsistently. Same 158 checks, no behaviour
change.
OBS SDK bootstrap for macOS/Windows. Adopts obsproject/obs-plugintemplate's
buildspec machinery -- buildspec.json plus cmake/common/buildspec_common.cmake
and cmake/{macos,windows}/buildspec.cmake -- so those two platforms get a real
libobs and build the actual plugin module instead of only the core library.
Linux is untouched and still uses Ubuntu's libobs-dev
(-DSTPLUGIN_BOOTSTRAP_OBS=OFF); the bootstrap only runs where there is no
system package.
Trimmed against upstream, each change recorded in the file that makes it:
- qt6 is dropped from dependencies_list on both platforms. The properties UI
is plain obs_properties_* and nothing here links Qt.
- The OBS sub-build builds and installs the `libobs` target, not
`obs-frontend-api`. Building the frontend API is what would drag Qt back in,
and this plugin never calls it.
- The sub-build is configured with ENABLE_UI=OFF and ENABLE_SCRIPTING=OFF as
well as upstream's ENABLE_FRONTEND=OFF: the pinned OBS predates
ENABLE_FRONTEND and gates its Qt-dependent UI on ENABLE_UI, so without this
it configures the whole OBS UI and demands Qt anyway.
- Only the Release configuration is built and installed, not Debug as well.
Nothing consumes a debug libobs and it doubles the slowest CI step.
- Only the dependency-acquisition modules are vendored. The template's
compilerconfig/defaults/helpers/xcode modules drive its own target and
bundle layout, which this project does not use.
obs-studio is pinned to 30.0.2, deliberately low: OBS refuses to load a module
built against a NEWER libobs than the one running it and accepts older ones, so
this pin IS the minimum OBS version users need. 30.0.2 is also exactly what
Ubuntu 24.04's libobs-dev ships, which puts all three platforms on one floor,
and it supports the modern CMake layout the bootstrap drives via
-DOBS_CMAKE_VERSION=3.0.0. prebuilt is obs-deps 2023-11-03 with the hashes
obs-studio 30.0.2's own buildspec.json publishes; the obs-studio source
archive hashes were computed from the GitHub tag archives.
The workflow also prints what was actually produced on each platform (ldd /
otool / dir over build/package) and uploads it as an artifact, so "does this
even link against libobs" is answered by CI output rather than assumed.
Verified locally: the Linux path is unchanged by all of this -- a fresh
configure still finds libobs-dev, and ctest is 6/6. The macOS and Windows
bootstrap can only be verified by CI; that is what this push is for.

ci: install cmake on the Windows runner before configuring
First CI run confirmed winvm-builder is a self-hosted act_runner labeled "windows-latest" but not the GitHub-hosted windows-latest image -- cmake isn't on PATH there (unlike the Linux/macOS runners, which do have working system/brew package managers). Use lukka/get-cmake to fetch a pinned cmake+ninja without needing admin/choco.

Scaffold core/OBS-adapter split, prove CMake toolchain, add 3-platform CI
First pass on the streamer-tools OBS camera plugin: a minimal but real CMake project matching the design doc's core-library/OBS-adapter split (docs/superpowers/specs/2026-09-06-obs-camera-plugin-design.md in the streamer-tools repo). No LiveKit FFI integration yet -- this proves the toolchain works. - core/: dependency-free C++17 library (no OBS dependency), unit tested via CTest with no external test framework. - obs-adapter/: adapted from obsproject/obs-plugintemplate (commit 3e7d7ac, 2025-12-09). Registers a real, stubbed OBS source type; builds as a genuine dynamically-linked OBS module against Ubuntu's system libobs-dev (confirmed via ldd/nm, not a fake stand-in). - Simpler hand-written top-level CMakeLists.txt in place of the template's full buildspec-driven bootstrap (which downloads full OBS source + prebuilt deps) -- find_package(libobs) alone is enough on Linux; falls back to core-library-only when libobs isn't found (expected on macOS/Windows CI for now). - .gitea/workflows/build.yml: 3-platform matrix (ubuntu-latest, macos-latest, windows-latest) matching the runners confirmed available to this repo under the CyberCoveLLC org.
