- Runners: ubuntu-24.04, macos-15, windows-latest (free tier) instead
of WarpBuild 8x/12x instances
- openfx-misc parallelism adapts to nproc (GitHub runners have fewer
vCPUs than the WarpBuild instances)
- Schedule a daily 03:17 UTC run so ccache entries never hit GitHub's
7-day cache expiry and system dependencies stay current
WarpBuild's cache service is billed; GitHub's cache is free (10 GB
repo limit with LRU eviction, ample for ccache entries). All three
cache sites — ccache for the matrix and dynamic-backend jobs, plus the
macOS OpenTimelineIO build — now use actions/cache@v4, which also
removes the Windows-specific fallback step.
Point CCACHE_DIR and the cache action at a fixed workspace directory
instead; checkout cleans untracked files before the restore, so the
ordering is safe.
- Restore ccache with WarpBuilds/cache@v1 on all three OS and the
dynamic-backend job (per-OS keys with branch fallback), and wire it
up through CMAKE_C/CXX_COMPILER_LAUNCHER; builds print ccache -s so
hit rates are visible in CI logs
- Cache the macOS OpenTimelineIO build (keyed on v0.16.0) and skip the
rebuild on cache hit
- Install ccache via apt/brew/MSYS2 as needed; CCACHE_MAXSIZE=1G
- Runner sizes 16x/32x -> 8x (macOS 12x kept); openfx-misc make -j8 to
match
- Extract libolive-rendercore static library to minimize backend link boundary.
- Add DynamicRenderer adapter with C ABI (oakgl/oakvulkan shared libs).
- Make OAK_ENABLE_DYNAMIC_RENDER_BACKEND default ON with OpenGL fallback.
- Implement VulkanRenderer prototype (textures, shaders, UBO blit, readback).
- Add backend-neutral viewer readback path (offscreen -> QImage -> QPainter).
- Refactor PluginRenderer to be renderer-agnostic; OFX plugins fall back to CPU
path on non-OpenGL backends while preserving OpenGL render path.
- Add Renderer::AttachOutputTexture/DetachOutputTexture and C ABI forwards.
- Update docs/zh/render-backend-dynamic-plan.md for Phase 3/4/5.
