A PC whose GPUs were installed from different driver packages of one vendor
(an ASUS G513QY: the integrated Radeon on the 2021 package, the RX 6800M on a
2026 one) gives the Vulkan loader two versions of that vendor's driver, and
the RX 6800M is listed once through each. wgpu's request_adapter takes the
first discrete entry, the 2021 driver's, and the window drawn through it dies
inside amdvlk64.dll (0xc0000005) before it paints: the main thread is in the
2021 driver, the fault on a thread of the 2026 one, no Rust frame anywhere.
Left to the #820 ladder, two crashed launches end in DirectX 12 only.
filmcraft_gpu::adapter::choose is wgpu's own rule (the adapters that can draw
to the surface, by device type for WGPU_POWER_PREF, then as enumerated) with
one addition: when the adapter that rule picks is listed again by the same
driver (same backend, device type, PCI vendor and device and driver name; the
same bus id when both report one), the entry exposing the most wgpu features
is used, i.e. the newer version (68 against 60 here, a strict superset).
Without such a duplicate the choice is wgpu's own, and entries of one GPU from
different drivers (RADV and AMDVLK, a vendor's driver and Dozen) are left
alone.
graphics::apply installs it as egui-wgpu's native_adapter_selector in the
default mode on Windows, as #609 was asked to be rebased onto the #827
start-up. DirectX 12 only, software mode and the other platforms keep their
adapter choice, and the ladder is untouched. The adapters and the choice go
to the log.
Tests: the laptop's listing (wgpu's rule picks the entry that crashed, choose
the other one), listings without two versions of one driver over every power
preference (choose equals wgpu's rule), surface, bus id and driver cases, and
one against the adapters of the machine running the tests (the rule is what
request_adapter returns there).

VP8 WebM showed black video: there was no VP8 decoder. New L0 crate
filmcraft-vp8, implemented from RFC 6386 sections 1-19 (tables extracted
from the RFC text, nothing from the attached reference decoder): every
coding tool, versions 0-3, hidden altref frames, size changes. Bit-exact
with libvpx on 62 libvpx VP8 test vectors, real-world FATE samples and
generated fixtures; never panics on corrupted input.
Wired into codecs for Matroska / WebM (V_VP8, including the alpha layer
of transparent WebM) and MP4 (vp08). VP8 colour is BT.601 (RFC 6386 9.2).
A hidden altref frame is a WebM block of its own with the time of the
frame that follows it: the VP8 time lookup now moves on to that shown
frame instead of repeating the previous one.

APNG and animated GIF files opened as stills showing only their first
frame. They now open as movie clips (crates/media/src/animated.rs):
- every frame is decoded and composited onto the full canvas by the
image crate (APNG blend/dispose ops, GIF disposal), keeping alpha
- each frame lasts its own delay; GIF delays <= 10 ms play as 100 ms
and APNG delays < 10 ms as 10 ms, as browsers do
- consecutive identical frames are merged; the clip is one pass of the
animation and its timebase is the most common frame length
- hostile input: at most 10,000 frames / 1 GiB of decoded pictures; a
damaged frame ends the clip at the frames before it; files with one
frame (or none that decode) still open as stills, as before
Tests: media unit tests (timing, transparency, merging, single-frame
files stay stills, truncated/bit-flipped files never panic) and an
engine test that imports an animated GIF and reopens it from a saved
project.

- release.yml: new `linux-riscv64` job, cross-compiled on ubuntu-24.04 against
ports.ubuntu.com riscv64 libs (ported from GridCraft), tar.gz only, CLI
smoke-tested under QEMU. Installs libasound2-dev:riscv64 for cpal/ALSA; the
VA-API and NVDEC/NVENC paths are loaded with libloading at run time, so they
need no riscv64 libraries. The draft-release job now needs it, so its tarball
is uploaded and covered by SHA256SUMS.txt.
- packaging/linux/package.sh: CROSS_ARCH / CROSS_TARGET / CROSS_COMPILE /
EMULATOR support, as in GridCraft.
- README and docs/releasing.md list the riscv64 tarball.
- cargo xtask version set 0.6.0 (Cargo.toml, Cargo.lock); refresh contributors.

The NVENC HEVC encoder (Main 8-bit SDR and Main 10 HDR PQ / HLG) was gated to
Windows. It now also runs on 64-bit Linux, on the CUDA device the H.264 encoder
already uses: the H.265 format and HDR probes are registered there and the
HEVC tests run on both systems.
NVENC registration on Linux now happens after the VA-API probe. Started beside
it, the background HEVC probe's first cuInit could deadlock with
libva-nvidia-driver, which calls cuInit from its library constructor under the
loader lock.

AviSource maps AVI streams onto the decoders, opened from bytes or a
streaming reader (Media Browser probe):
- Video: Motion JPEG, H.264 and HEVC (Annex B, our decoders) and
uncompressed BGR24 / BGRX32 / YUY2 / UYVY / I420 / YV12 / NV12 / grey
(new RawVideoDecoder). Empty "drop frame" chunks hold the picture
before. AVI has no timestamps: H.264 with B-frames is stored in decode
order, so the presentation order comes from the pictures' order counts
(mxf::avc_presentation_order), keeping the slots the pictures occupy.
A writer that kept a fine time base (ffmpeg copying an MP4's 1/600)
fills the slots between pictures with empty chunks; the reported frame
rate is the one the pictures play at. DivX / Xvid and DV are named and
report that they have no decoder; their sound plays.
- Audio: PCM (integer and float) from the chunks; MPEG audio and AC-3
frames, which AVI chunks need not follow, found again across chunk
boundaries with the new filmcraft_mpegts::frame_bytes.
- Motion JPEG frames without Huffman tables (the AVI1 convention) decode
with the standard ITU-T T.81 Annex K tables (also for MOV).
Tests against ffmpeg's decode of the same files: H.264 with B-frames
bit-exact under random access, also copied from a 1/600 MP4;
uncompressed video and PCM bit-exact; JPEG and MP3 / MP2 / AC-3 within
decoder tolerance; drop frames; DivX; JPEG without tables equal to the
same frame with them. Engine: an AVI imports, makes a sequence, plays
picture and sound, and probes without reading it whole.

tests/setting.rs: keep the check against the backend register() reported
(main's fix expects VA-API on Linux, which NVDEC now sits in front of).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Adds a second Linux decoder backend, crates/platform/src/nvdec, that talks to
NVIDIA's driver directly (libnvcuvid + the CUDA driver, both loaded at run
time). It is registered in front of VA-API: what NVDEC declines still reaches
VA-API, then the software decoders. H.264 8-bit and HEVC 8/10-bit, 4:2:0
progressive.
NVIDIA's parser takes Annex B access units, so there is no host-side DPB.
Pictures are read back as NV12 / P016 through the existing biplanar path and
are bit-exact with the software decoders. The CUDA context is the one
nvenc::device already retains; it gains push/pop and copy-to-host. A seek
recreates the parser and keeps the decoder.
Also fixes tests/setting.rs, which expected the Media Foundation backend name
on Linux, and updates the Hardware decoding tooltip and its Spanish row.

main gained NVENC H.265 Main / Main 10 (#328, #360), export stage timings
(#370) and VA-API decoding (#358). Resolution: main's NVENC session, FFI and
export factory, with this PR's changes ported onto them:
- ffi: the portable Guid (now also for the HEVC GUIDs), NV_ENC_DEVICE_TYPE_CUDA;
- session: device.rs (Direct3D 11 / retained CUDA primary context), the
Linux libnvidia-encode.so.1 loader, Device::KIND;
- export: factory_with and its tests, the even-size check, the saturating
max bitrate; H.265 through NVENC stays Windows-only (the factory declines
it on Linux, where nothing probed or tested it);
- Cargo.toml: main's Linux libloading dependency covers both users;
- docs: README / ROADMAP / architecture now say NVENC H.264 runs on Windows
and Linux; ADR and platform README keep both addenda / test rows;
- abi_tests: note why the MSVC-generated expectations hold on LP64 Linux.

The tarball now ships install.sh. It installs filmcraft, filmcraft-cli,
the desktop entry, icons, MIME type, metainfo and docs under ~/.local
without sudo; --prefix takes any absolute path (sudo ./install.sh
--prefix /usr/local for all users). Running it again updates.
The desktop entry's Exec/TryExec point at the installed binary's
absolute path, escaped per the Desktop Entry spec, so the menu entry
works without ~/.local/bin on PATH. The script checks the bundle is
complete before writing, refuses /, prefixes inside the extracted
bundle and characters launchers cannot express (=, %, control
characters), and treats the cache refresh tools as optional.
packaging/linux/test_install.py covers install and update, launching
through gio, bad arguments, an incomplete bundle, --help and a real
package.sh tarball build; Packaging lint runs it.

HDR sequences export as real 10-bit HEVC Main 10 through NVENC where the GPU
reports 10-bit HEVC: float BT.2020 R'G'B' -> rgbf_to_yuv420_10 -> P010 input;
VUI BT.2020 + PQ/HLG; HDR10 mastering-display / content-light as SEI on every

tone-mapping HDR sequences to 8-bit SDR HEVC. ABI asserts extended and

the two #328 tests that asserted HDR is declined now expect Main 10.

HEVC through VA-API the same way as H.264: the software HEVC decoder's
parsers and DPB (now generic over the picture type in filmcraft-hevc:
POC, reference picture sets, reference lists, output order, RASL
handling) drive the stateless hardware. Main, Main 10 and Main Still
Picture, 4:2:0 8/10-bit (P010 read-back); scaling lists, tiles, WPP,
dependent slices, weighted prediction. Missing references and range
extensions go to the software decoder.
Tests: hardware parity on HEVC Main / Main 10 incl. open GOP, scaling
lists, slices+WPP, weighted prediction, tskip+AMP, 1080p/2160p (streamed
comparison to stay within memory); HEVC front end against a recording
stand-in on every OS; ABI checks extended to va_dec_hevc.h. Benchmark on
Iris Xe: 4K HEVC 203 -> 10 ms CPU per frame, 4K Main 10 212 -> 18 ms.

Stateless VA-API decoding with FilmCraft's own H.264 host side: the
software decoder's SPS/PPS/slice-header parsers and its DPB (now generic
over the picture type in filmcraft-h264) drive the GPU, so reference
marking, reference lists and output order are shared and the pictures are
bit-exact with the software decoder. libva is loaded at run time; no libva
or driver means software decoding as before. frame_num gaps (open-GOP
seeks) get the software decoder's stand-in frames. HybridDecoder keeps the
transparent software fallback.
Tests: hardware parity on 7 H.264 streams incl. 1080p/2160p, seeks,
flushes, forced failures, fuzzing, concurrency; front end against a
recording stand-in on every OS; ABI checks against va.h. Docs: platform
README, ADR 0001 addendum, architecture, performance (H.264 2160p CPU per
frame 417 -> 11 ms on Iris Xe), roadmap.

eframe's default wgpu instance enables PRIMARY | GL on Windows. Creating
the OpenGL backend can crash inside AMD's atio6axx.dll before the window
appears, so the app flashes in Task Manager and exits. When WGPU_BACKEND
is not set, the Windows instance now enables only DirectX 12; an explicit
WGPU_BACKEND is still honoured. macOS, Linux and web are unchanged.

Properties panel: the diamond on a row was the stopwatch (effects.toggleAnimation),
so clicking it on a keyframe dropped every keyframe and kept the value at the
playhead. It is now Add/Remove Keyframe (effects.addKeyframe), as in Premiere:
it turns animation on with a keyframe at the playhead, adds one there, or removes
the one there, and the value falls back to what the remaining keyframes give in
Properties, Effect Controls and the Program monitor. An animated row shows the
navigator (previous / diamond / next); the diamond is filled only while the
playhead is on a keyframe. Crop's diamonds work too (the effect is applied first).
Effect Controls: the keyframe lane has a time ruler (ticks and sequence timecode
over the clip's stretch of the sequence) with the playhead's handle on it; click
or drag the ruler to move the playhead. The playhead is drawn only while it is on
the clip. Both panels share one navigator widget, with automation ids
<panel>.<effect>.<param>.addKeyframe / .prevKeyframe / .nextKeyframe, plus
effectControls.ruler and effectControls.playhead.
Tests: engine add/remove at the playhead with undo, redo and bad parameters;
headless UI tests of the navigator, Crop and the ruler; ruler labels and limits.

- release.yml: new `flatpak` jobs (x86_64 on ubuntu-24.04, aarch64 on ubuntu-24.04-arm) that
repackage the Linux tarball as filmcraft-<v>-linux-<arch>.flatpak, and a `freebsd` job that
builds filmcraft-<v>-freebsd-x86_64.tar.gz in a FreeBSD 14.3 VM; both feed the draft release.
- AppImages embed gh-releases-zsync update information and ship a .zsync beside them; the
Linux job checks both.
- Jobs that sign nothing (version, Linux, Flatpak, FreeBSD, web) no longer use the `release`
environment, so a dispatch on a branch dry-runs them; the signing jobs and the draft-release
job stay in the environment, so nothing is published from a branch.
- packaging/linux/flatpak-bundle.sh + bundle manifest (same runtime and finish-args as the
Flathub manifest; packaging-lint checks they agree), packaging/freebsd/package.sh (with a
--dry-run that packaging-lint runs), and a nightly FreeBSD build workflow.
- README: Downloads section listing every build; docs/releasing.md updated.

Merge origin/main into the NVENC branch. #183 already provides the
HardwareEncoding enum, ExportSettings.hardware_encoding, the
hardwareEncoding export param and the Export > Video > Hardware Encoding
checkbox, so the duplicates from this branch are dropped and NVENC uses
them. filmcraft-export is now an all-platform dependency of
filmcraft-platform (VideoToolbox and NVENC both register encoders).
Never-crash fixes in the NVENC backend:
- submit() rejects a driver input pitch narrower than a row (and unlocks
the buffer); fill_nv12 uses get_mut instead of slicing rows.
- composition offsets use saturating math and i32::try_from; frame-rate,
size and timestamp casts are checked; sizes above u16::MAX decline.
- Annex B scanning and NAL type checks use get()/first().
- A failed nvEncOpenEncodeSessionEx that returns a handle destroys it.
ffi.rs carries NVIDIA's MIT notice for nvEncodeAPI.h, listed in
ATTRIBUTION.md under a new "Third-party source code" section.

Adds `Format::Hevc` (Export > Format > H.265 (HEVC); `"format": "hevc"` in
`file.exportMedia`): HEVC Main, 8-bit 4:2:0, in MP4 (`hvc1`) or QuickTime, with AAC audio,
encoded by the macOS hardware encoder. There is no built-in H.265 encoder (one in pure Rust
is a project of its own, and x265 is GPL), so the format exists only where the OS has one.
- `videotoolbox_encode`: the session wrapper creates HEVC sessions too (`VtProfile::HevcMain`;
the profile also says which codec). Keyframes are the HEVC random access points (NAL types
16 to 21); the parameter sets are VPS / SPS / PPS; the `hvcC` record in the MP4 sample
entry is the one VideoToolbox writes (sample description extension atoms), so profile,
level and flags are the encoder's own. `VtEncoder::uses_hardware()` asks VideoToolbox
whether the session runs on a hardware encoder (a test checks H.264 and HEVC), so a
requirement dropped by accident could never become a silent software encode.
- `hardware_encode`: one adapter for both codecs. Choosing the format is the opt-in (the
`hardware_encoding` setting is for H.264). `hevc_available()` (one small hardware session,
created once) is registered with the new `filmcraft_export::register_format_probe`, so
`available(Format::Hevc)`, the format list of Export mode and `exportFormats` follow the
machine. `Format::has_builtin_encoder` says which formats need such a probe.
- `export`: `Format::is_h26x` where H.264 and H.265 behave alike (MP4 or QuickTime, AAC, size
estimate, summary line). Two-pass VBR is refused up front ("H.265 export has no two-pass
mode") and HDR sequences export as SDR, because there is no encoder to fall back to.
- Export mode: H.265 shows H.264's multiplexer, audio, metadata and bitrate controls, without
profile, level, two-pass or the hardware checkbox, and says "Encoder: Hardware".
Apple M1 (8 cores), 1080p25, a 9:29 timeline (camera clip, ProRes 4444 overlays, AAC,
loudness): hardware H.265 at 10 Mb/s 195 s, hardware H.264 at 20 Mb/s 204 s (CPU 1029 s and
1042 s; the same H.264 export took 193 s and 200 s on other runs). It is not faster: the codec
that compresses further is the more expensive one (raw encoders: 166 and 189 frames/s), and
the export is bound by the CPU compositor, not by the media engine.
Quality per bit, 30 s of the same timeline against a ProRes 422 HQ export (average PSNR over
the three planes, SSIM): 20 Mb/s 46.88 dB / 0.9902 (H.264) and 46.91 dB / 0.9903 (H.265);
10 Mb/s 44.96 / 0.9863 and 45.09 / 0.9863; 6 Mb/s 43.72 / 0.9833 and 44.31 / 0.9843; 4 Mb/s
42.91 / 0.9807 and 43.64 / 0.9825; 3 Mb/s 42.37 / 0.9786 and 43.05 / 0.9807. The same picture
at 10 Mb/s and above; at 3 to 6 Mb/s H.265 needs 22 to 31 % less bitrate for the same PSNR.
Both formats therefore keep the same default bitrate. Details in docs/performance.md (HW3).
Tests: tests/hardware_encode.rs gets the HEVC counterparts of the H.264 ones (what is taken
and declined, a round trip through our HEVC decoder with luma PSNR above 30 dB, keyframes, MP4
and QuickTime exports with AAC, ffmpeg / ffprobe reading `hevc` / `Main` / `hvc1` /
`yuv420p` / BT.709, exact sizes, hostile configurations, encoders dropped at any point, the
format list agreeing with the probe, sessions on the hardware encoder); settings_tests.rs
checks names, ids, defaults, the summary, two-pass refusal and the probe; export_ui.rs the
controls H.265 shows and hides.
Stacked on the hardware H.264 encoder (the first commit of this branch).
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Export encodes H.264 on the CPU with the built-in encoder, which is most of the time
of an export (about two thirds of the busy CPU in a profile of a 20 s export). On
macOS the media engine can do it: a VideoToolbox compression session behind
`filmcraft_export::VideoEncoder`, registered by `filmcraft_platform::register()`.
- `ExportSettings::hardware_encoding` (`HardwareEncoding::Off` | `Auto`; Export > Video >
Hardware Encoding, `"hardwareEncoding": "off|auto"` in `file.exportMedia`, a boolean is
understood too), off by default: the built-in encoder's output is byte-identical on
every machine, a hardware encoder's is not.
- `videotoolbox_encode` (FFI, same containment as the decoder: SAFETY comments, no
panic across the callback, safe API) and `hardware_encode` (safe adapter and factory).
- The factory declines, so the built-in encoder is used, for other formats, MXF, two-pass
VBR, HDR, odd sizes, non-square pixels and any configuration VideoToolbox cannot create a
hardware session for. An encoder that fails mid-export stops it with an error: unlike a
decoder, it cannot hand a half-written stream to another one.
- No B-frames: on real 1080p footage the quality is the same with and without them
(+-0.3 dB at equal bitrate) and the bitrate lands closer to the target, and without
them every frame is presented at its decode time (no composition offsets, no edit list).
- `export::register_encoder` ignores a factory registered twice; `encoder_registered`.
Apple M1, 8 cores, single runs: a 9:29 timeline (camera clip, ProRes 4444 overlays with
alpha, AAC, loudness) exports in 311 s instead of 793 s (2.5x faster); its densest 134 s
in 84 s instead of 395 s (4.7x). The outputs compare at SSIM 0.990 / PSNR 46.5 dB. The encoder
alone runs 200 fps at 1080p (docs/performance.md).
Tests (tests/hardware_encode.rs): what is taken and declined, a round trip through our
software decoder, an export that decodes in our decoder and in ffmpeg, the fallback for
everything hardware declines, exact output sizes, an empty range, hostile configurations
and encoders dropped at any point; the engine's `hardwareEncoding` parameter.

ffmpeg prints "corrupt decoded frame" as a warning, so the oracle's
`-v error -ec 0` decode let a stream with a whole slice missing pass
silently. Switching that decode to `-v warning` is not enough: with
`-ec 0`, ffmpeg 7.1/8.1 flags every picture that has more than one
slice, libx264's multi-slice streams included, while the pixels are
unchanged. That is the 119/120 in #74; the encoder's bitstream is not
at fault (VideoToolbox decodes the same streams bit-identically, and
ffmpeg with strict error detection reports nothing).
The oracle now decodes with ffmpeg's default concealment, `-v warning`
and `-err_detect +crccheck+bitstream+buffer+explode`, fails on any
output or a non-zero exit, and still compares every pixel with the
encoder's reconstruction. A negative control drops and truncates
slices (CAVLC and CABAC, 3 slices) and checks the oracle reports each
one; it fails with the old flags.

The merged Japanese interface (#38) looked only for a system font. When
FilmCraft is built with craft-fonts, theme::install already appends the
Japanese faces to every font family, so switching to Japanese uses them
(no system scan) and works on the web too; otherwise it falls back to an
installed system font as before. Docs use an absolute CRAFT_FONTS_DIR
(build.rs runs in crates/text, so a relative path resolves from there).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
crates/text/build.rs embeds the fonts of a storytold/craft-fonts checkout
named by CRAFT_FONTS_DIR as filmcraft_text::fonts::CRAFT_FONTS (native:
all of them; wasm32: only BIZ UDPGothic Regular). Unset, CRAFT_FONTS is
empty and nothing changes. A bad CRAFT_FONTS_DIR is a warning, or an
error with CRAFT_FONTS_REQUIRED=1. Never a Cargo dependency, no network.
- UI: the Japanese faces are the last fallback of every egui font family
(BIZ UDPGothic first, Bold first in the semibold/medium families).
- Text engine: registered after the bundled faces; fallback_for picks
them after the bundled faces and before system faces (Mincho for serif
text, Gothic otherwise, nearest weight).
- Tests: Japanese glyphs (no tofu) in the UI and title paths, skipped
without craft-fonts; the theme works with CRAFT_FONTS empty.
- Release: every build job checks out craft-fonts at a pinned commit and
builds with CRAFT_FONTS_DIR + CRAFT_FONTS_REQUIRED; packages carry
OFL-<family>.txt. NOTICE, ATTRIBUTION.md (optional build input), AGENTS.md,
CLAUDE.md, README and docs/contributing.md describe it.
FilmCraft main bundles no Japanese font, so no font files move.

ROADMAP honest assessment, Where we are lacking and Running now; README status and codec note. 35 crates (platform).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
ROADMAP now reports two numbers: the feature checklist (~87%, what exists)
and ready for real work (~50-60%, an honest estimate). Adds a by-dimension
assessment with evidence, a prioritised "Where we are lacking" list (hardware
acceleration, a measured parity tool, real-world media corpus, workflow
acceptance tests, Windows/Linux runtime CI, delivery codecs, plugins, AI, web),
and where we're going. Fixes stale rows (M5 effect count, Running now) and logs
2026-10-05.
README: the stale "45%" status replaced with both numbers and the biggest
gaps; the codec note now lists what imports today and what's missing.
docs/agents.md: agents read the honest assessment first, prefer its gaps,
and report progress as measured vs estimated.
