oak-cli and oak-render-worker use the C ABI exclusively (0 olive::
symbols). Google Test suites updated for the migrated APIs, new engine
facade test coverage, CLI transcode verification.
- oak-render-worker now builds from worker/ (own CMakeLists.txt) as a
peer of app/; RenderWorkerPool resolves the new build-tree location
- deduplicated the Linux install() rules for the worker
- worker-spawning tests resolve build/worker instead of build/app
- cd.yml: Windows staging copies the worker from its new output path
The CI runner has no Vulkan runtime (liboakvulkan.so fails to load) and
no display (offscreen QOpenGLWidget cannot create a context). The
viewer display tests only checked that the parameter was "vulkan", so
they ran on the OpenGL fallback and segfaulted with no usable GL
context. Probe the backend the same way the other render test fixtures
do (load, verify the backend kind actually matches the request, init)
and skip when it is unavailable. Also replace the stale "temporary
scratch test" file header now that this is a committed regression test.
ClipBlock::kBufferIn is declared as NodeValue::kNone with no value
hint, so when a footage node is connected straight to a clip's buffer
input (no effect node in between), the traverser has no type to look
up in the footage's value table and falls back to its last entry. A
footage pushes its video texture first and its audio samples last, so
a video clip ended up fed with audio samples, produced no texture and
the preview went silently black. With any node in between, the table
only carries the passthrough texture, which is why the bug only showed
on direct connections.
Make Node::GetValueHintForInput virtual and override it in ClipBlock
to prefer the value type matching the clip's track (kTexture on video
tracks, kSamples on audio tracks).
Regression tests cover the exact application render path
(PreviewAutoCacher -> RenderManager -> RenderWorkerPool ->
oak-render-worker) for both the direct and indirect cases, the hint
following the track type, and viewer display widgets. The direct-case
test reproduces the black frame without the fix and passes with it.
Full suite: 584 passed.
