This directory builds a Linux command line replay runner for apitrace files. It is meant for CI coverage of MobileGL without Android, APK packaging, FCL, or plugin runtime dependencies.

The bundled openra fixture comes from GL4ES' apitrace corpus. See GL4ES_TRACES.md for the current inventory and the traces that were rejected because they rely on compatibility/fixed-function OpenGL.

Build from the MobileGL repository root:

cmake -S . -B build-test -G Ninja \
  -DMOBILEGL_BUILD_TEST=ON \
  -DMOBILEGL_BUILD_BENCHMARK=OFF \
  -DMOBILEGL_BUILD_TRACE_REPLAY=ON
cmake --build build-test

Run the OpenRA fixture test:

ctest --test-dir build-test -V -R MobileGLTraceReplay.OpenRA

Run the CLI directly:

build-test/tools/trace_replay/mobilegl_trace_replay \
  --trace openra.trace \
  --golden openra.0000031249.png \
  --output out/openra \
  --backend DirectGLES \
  --mobilegl-library build-test/libMobileGL.so \
  --target-call 31249 \
  --width 640 \
  --height 480 \
  --crop-x 1 \
  --crop-y 1 \
  --crop-width 638 \
  --crop-height 478 \
  --tolerance 20 \
  --fuzz-percent 20

The Linux runner loads MobileGL by path with dlopen. It uses an EGL pbuffer for DirectGLES and maps the pbuffer path to VK_EXT_headless_surface for DirectVulkan, so CI does not need an X11 or Wayland window.
