1.3.0 linked libVkLayer_fdm_darken.so into every arm64 game's engine library; in libCryRenderVulkan.so CrySystem
initialization then fails right after the renderer lists its Vulkan device extensions, and the shutdown crashes
(SIGSEGV in CSystem::ShutDown). Bisected headless on the dev Frame by swapping libraries between the September
known-good APK and a current build: only the modified renderer breaks it. Climb 2's private VrApi bridge still
loads the layer itself (72 fps headless with this change). frame.adapter package revision 3 for both games;
triage cryengine-init-failed.
With Quest 3 the game switches to a 2592x2256 eye buffer after the intro; by then its UI panels have used up the
runtime's ~15 swapchains per session, so the new eye buffer is refused (XR_ERROR_LIMIT_REACHED) and it stops
drawing. Headless on the dev Frame, same build: Quest 3 frames stop, Quest 2 holds 72 fps.
From issues #409#410#412#418#421#435#441#447#448#453#456#461#462#464#472 via
scripts/catalog_from_issue.py. GoldenEye VR (no sound), JKXR (stutters after minutes) and Umurangi Generation
(freezes when saving a photo) are "issues"; Simpsons and Astro VR Host setup steps point to the Files tab, the
long instructions moved to details.
The software Main 10 path narrowed HDR10 pictures to 8 bits as they were, so
PQ shown as SDR looked grey and BT.2020 colours dull. hdr_tonemap.h maps
brightness with BT.2390's EETF (203 cd/m2 reference white = SDR white,
highlights rolled off up to MaxCLL / the mastering peak / 1000 cd/m2) and
converts colour per chroma sample through linear light into BT.709, moving
out-of-gamut colours toward grey of the same luminance. The component then
prefers its bitstream colour aspects, so surfaces and its RGBA conversion see
BT.709. Bands run in the colour helper threads (about 10 ms per 1080p picture
on one big core). Decoder revision 10; artifacts rebuilt with build.py.
Iris on the Frame's kernel (6.18) offers HEVC Main 10 only into its
compressed Q10C capture format. The component always asks for NV12, and a
Main 10 stream in such a session returned no pictures: playback stayed at
0:00, the flush on leaving timed out (ACodec -110) and the next video hit
MediaCodec::reclaim, so every later decoder start in the app failed until it
restarted (seen in Bigscreen Beta with local files over DLNA).
- hevc_profile.h reads general_profile_idc from the parameter sets
(CODECCONFIG or the first access unit, Annex B or hvcC); streams beyond
Main never open Iris and decode in FFmpeg's software HEVC decoder, which
the component already contains.
- Its 10-bit planar pictures are rounded to 8-bit planar before the existing
outputs (no HDR tone mapping).
- The HEVC component lists Main 10 (level 5.1), so format-aware players
select it instead of reporting NoSupport and using it anyway.
- Decoder revision 9; artifacts rebuilt with native/hevc/build.py (the same
toolchain rebuilds revision 8 byte for byte).
Tested on a Steam Frame in Bigscreen Beta: 1080p and 4K Main 10 clips and a
real 1080p Main 10 episode play; 8-bit HEVC and H.264 afterwards play too.
FFmpeg's software HEVC decoder on the Frame's CPU, 4 threads as the
component uses: 1080p Main 10 episode 232 fps, synthetic 4K Main 10 72 fps.
The owner's tuned room-scan cleanup (2026-10-18) ported to C, pass for pass: plane offsets re-estimated from the
scan, one-sided structural bands, flat wall/floor/ceiling panels (or snap), near clearing, erase spheres, the walked
volume from the recording's head path, furniture tops, clipping with the unseen-edge allowance, islands, thin
floating pieces, Taubin smoothing; label rules on the scanner's volumes (merged/nested/outside boxes removed, shape
relabelling, SCREEN flatness from the raw mesh, door/closet suggestions in scan.json).
room.txt + room-mesh.bin are now refined (ceiling re-estimated); the unrefined output stays as room-raw.txt +
room-mesh-raw.bin with the same UUIDs; scan.json holds heads, settings, report, labels, suggestions. The scan path
refines its raw files as read back, so --refine-only on them reproduces the scan byte for byte; --refine 0 writes
the old output. The fusion grid is freed before the refinement (peak memory unchanged).
- detect: many Meta XR SDK games carry the Depth API without using it; until a headset check shows more games
with the symptom (or OVRPort is found advertising XR_META_environment_depth, which a FrameBridge hide setting
would fix generally), the patch comes from Laser Dance's catalog recipe or the user's choice.
- ApkWorkspace.size/contains: entries are searched in 4 MiB chunks instead of read whole.
- Laser Dance: the fixes' original values at all seven places together identify the build (no versionName was
recorded with them); another build gets none of them.
- tests: lz4 is skipped when missing, the known/unknown Laser Dance build, chunked search.
The PR turned it on for every Unity game with USE_SCENE or MRUK's library: a game-logic change keyed to one
game's symptom (MRUK games mostly don't use OVRSceneManager at all). A scanned room around the player usually
passes IsUserInRoom by itself.
