Independent firefox-fourier campaign (RK3399 H.264 stateless via
rkvdec) overlaps significantly with David's HEVC work outlined in
comment #3 — same gfxinfo / FFmpeg / sandbox plumbing. Posting our
findings, including a non-obvious sandbox/libudev interaction
(Mozilla's OpenAtTrap rejects fd-relative openat used by systemd's
chase() inside udev_enumerate_scan_devices), would save duplicate
effort.
Draft is the proposed comment text plus upload notes. Final
submission still needs human review + bugzilla account to post.
