Feature flags (FEATURES= make variable):
glfw — GLFW + OpenGL viewer (libglfw3, libglew)
vulkan — future Vulkan renderer
turbojpeg — MJPEG decode/encode (libturbojpeg)
xorg — XRandR geometry + screen grab (libx11, libxrandr)
vaapi — VA-API hardware codec (libva)
Each flag injects -DHAVE_<FEATURE> and the relevant pkg-config flags.
Headless build: make (no FEATURES set).
test_image module (src/modules/test_image/):
Generates test frames in YUV420, YUV422, and BGRA.
Patterns: SMPTE 75% colour bars, greyscale ramp, white/black grid.
BT.601 limited-range RGB→YCbCr in write_pixel().
test_image_cli (dev/cli/):
Generates a frame and writes it as a PPM file for visual verification.
Usage: test_image_cli [--pattern bars|ramp|grid]
[--width N] [--height N]
[--format yuv420|yuv422|bgra]
--out FILE.ppm
xorg module (src/modules/xorg/):
xorg.c — full GLFW+OpenGL implementation (compiled with FEATURES=glfw)
xorg_stub.c — no-op stub (compiled otherwise; xorg_available() returns false)
Renderer: full-screen quad via gl_VertexID, three GL_R8 textures for YUV,
BT.601 matrix in fragment shader, GL_BGRA texture for packed frames.
MJPEG path: tjDecompressToYUVPlanes → planar YUV → upload (requires turbojpeg).
push_yuv420/push_bgra/push_mjpeg all usable independently.
