Firefox 150.0.1 + media.ffmpeg.vaapi.enabled=true + LIBVA_DRIVER_NAME= v4l2_request, executed under Xvfb on ohm. Result: inconclusive at the boolean-correctness level. RDD process dlopens libva.so.2 + libva-drm.so.2 + libva-x11.so.2 for capability probe then immediately closes them; never reaches vaInitialize, never opens /dev/dri/renderD128, never reaches v4l2_request_drv_video.so. Falls back to software H.264 in RDD via FFmpeg-OS-library PDM (Broadcast support from 'RDD', support=H264 SWDEC). Root cause: Xvfb provides software framebuffer with no DRI/DRM render-node integration. Firefox's gfx-environment platform-fitness check rejects VAAPI before adding it to the RDD PDM order list. Not a libva-side or driver-side fault — mpv --hwdec=vaapi-copy in the same headless rig DID engage end-to-end (per phase0_evidence/2026-05-04/findings.md). Definitive Firefox verdict requires retesting inside a live Plasma session — deferred to live-session run (next commit). Also: Phase 0 deliverable #2 (Step 1 reconciliation into fork master) was completed and pushed to marfrit/libva-v4l2-request-fourier between this and the prior Phase 0 commit; status table updated.
