The MP4 reader took the AudioSpecificConfig's channel configuration as a
count, but it is an index into ISO/IEC 14496-3 Table 1.19: configuration 7
(7.1) reported seven channels and dropped the last decoded one, and 12
(7.1 back, what ffmpeg 9 writes for 7.1) reported twelve. Count from the
table (with Amd 4: 11 → 7, 12 and 14 → 8, 13 → 24), and decode
configurations 11 and 12, reordered to the WAV/SMPTE order used for 5.1.
Checked against ffmpeg's decode channel by channel.

Keep FLAC beside main's new AAC Audio format (21 formats, both audio-only
presets), use is_mp4_with / is_mp4_video in audio_codec() and the Audio
Format picker so MP4 (incl. AV1) offers AAC or FLAC, and add flacLevel to
main's export.media params.

Problem: MP4 and QuickTime name MPEG audio without its layer (ffmpeg
stores MP2 as `mp4a` + esds object type 0x6B), and we always made the
layer III decoder for it. symphonia's decoder reads only the layer it
was made for, so every MP2 frame was rejected and the track played as
silence; MOV's `.mp2` sample entry was not recognised at all.
Fix: the MPEG audio decoder for MP4 / MOV is made on the first packet,
for the layer its frame header names (ISO/IEC 11172-3 2.4.2.3);
`.mp2` maps to the MPEG audio codec like `.mp3`; the track is labelled
"MPEG Audio" for layers I/II, as Matroska's is. Decoded tracks now match
ffmpeg sample-exactly (edit list trims the 481-sample encoder delay).

Format::Av1 in export settings and jobs, SampleEntry::av1 (av01 + av1C) in
isobmff, and the Export panel's Format list, profile and encoder rows. No
encoder ships here: like H.265, AV1 is listed greyed out until a platform
encoder registers a probe, and a job without one fails with "AV1 encoder not
available yet". Split out of #409; the VA-API AV1 encoder follows on main's
vaapi::va design.

No conflicts. main's new Chinese catalog requires every tl! string:
added zh-CN for the FLAC labels (format, preset, Audio Format entry,
Compression Level and its hint).

New L0 crate filmcraft-flac, a FLAC encoder written from RFC 9639:
constant / verbatim / fixed / LPC subframes (Levinson-Durbin on Tukey-
windowed autocorrelation, up to order 12), partitioned Rice residuals,
left/side, side/right and mid/side stereo, CRC-8/CRC-16, STREAMINFO with
MD5 (RFC 1321, own implementation), levels 0-8, all lossless.
Export:
- Format::Flac, an audio-only .flac (16/24-bit), streamed one second at
a time like WAV/AIFF; STREAMINFO is rewritten at the end with frame
sizes, total samples and MD5. Preset "FLAC 48 kHz 24-bit".
- AudioCodec::Flac in MP4 and QuickTime (fLaC + dfLa), one frame per
sample with the short last frame timed exactly; the dfLa STREAMINFO
is replaced before the moov is written (Mp4Writer::set_sample_entry).
MXF stays PCM.
- AudioSettings::flac_level (default 5); Export panel: FLAC (lossless)
audio format and Compression Level; file.exportMedia `format: "flac"`,
`audioCodec`, `flacLevel`. Spanish and Japanese strings.
ffmpeg oracle: every stream decodes bit-exactly with the STREAMINFO MD5
equal to ffmpeg's hash; .flac and FLAC-in-MP4/MOV exports decode to the
same samples as a WAV export of the range.

The MP4 source reported the sample entry's size, only swapped for the display rotation, so two
crops were lost: the codec's own (H.264 SPS frame cropping, HEVC conformance window), which the
decoder applies but the reported size and sequences made from the clip didn't, and the clean
aperture (`clap`), parsed but never used. An iPhone clip (1920x1440 coded, 1744x1308 clean
aperture, -90 degree display matrix) showed 1440x1920 instead of 1308x1744.
H.264 / HEVC sizes now come from the stream's parameter sets; the clean aperture is a rectangle
inside that picture (ignored when it makes no sense), reported as the size and cut from every
frame by the GOP cache before the display rotation, through the new VideoFrame::cropped.
Tests: bit-exact against ffmpeg (which applies both crops) for an H.264 SPS crop, an HEVC
conformance window, centred and off-centre clean apertures and a clean aperture with a rotation;
clean apertures that make no sense are ignored without a panic; VideoFrame::cropped on every pixel
format with odd sizes and misaligned corners.

- Move conditional no-op match arms into guards
- Preserve renderer predicate order with De Morgan's law
- Strict clippy, fmt, layers, assets and WASM pass on Rust 1.95
- Clean engine runs match main: 379 pass, 10 fail, 3 ignored
- Full CI is not green; upstream baseline failures remain
aac, bitstream, cfb, color, format, frame, geom, isobmff, media, scopes, speech, the desktop
app and the web app have no production unwrap/expect/panic/unreachable (the web app's two
`expect`s — frame-cache eviction and chunked file reads — become `let … else`); each now
carries `#![deny(clippy::unwrap_used, …)]` outside tests so it stays that way.

Rust/clippy 1.99 added `chunks_exact_to_as_chunks` and tightened
`needless_late_init` and `drain_collect`, failing `clippy -D warnings`
on main.
- `chunks_exact(N)` / `chunks_exact_mut(N)` with a constant N become
`as_chunks::<N>()` / `as_chunks_mut::<N>()` (fixed-size arrays, so
several byte reads drop their per-element indexing). relink's
fingerprint uses the `(chunks, remainder)` split; its hash output is
unchanged.
- Late-initialised `let`s in ac3 bit allocation and opus CELT
bands/rate become `let x = if/match …`.
- `dpb.drain(..).collect()` becomes `std::mem::take(&mut dpb)`.
No behaviour change; `cargo xtask ci` passes.

Phones record portrait video as landscape pictures plus a rotation in the
container: the MP4/MOV tkhd matrix (ISO/IEC 14496-12 §8.3.2) or the
Matroska Projection pose roll (RFC 9559 §5.1.4.1.28.46). The matrix was
parsed but never used, so every portrait iPhone clip imported sideways
at its landscape size.
- isobmff: Track::display_rotation() reads 0/90/180/270° from the matrix
signs (mirrored / sheared matrices are left alone).
- matroska: parse Projection (type, yaw, pitch, roll);
VideoInfo::display_rotation() for rectangular projections.
- frame: VideoFrame::rotated() turns every plane at its own resolution
(4:2:2 chroma is widened to 4:4:4 for quarter turns) and swaps the PAR.
- codecs: Mp4Source / MkvSource report the displayed size and PAR, and
GopCache rotates decoded frames before caching them.
- web: the WebCodecs source configures the decoder with the coded size
and rotates its output the same way.
Tests: a one-frame ProRes MOV built in the test with 0/90/180/270°
matrices (reported size + which half ends up on top), plane rotation for
RGBA / 4:2:0 / 4:2:2, and a synthetic Matroska file with a -90° roll.

5.1 / multichannel:
- audio-dsp::channels: layouts (L R C LFE Ls Rs), ITU-R BS.775 up/downmix, 5.1 Mixdown Types,
equal-power 5.1 panner (puck, Center %, LFE).
- Mixer graph buses are 2 or 6 channels wide; 5.1 tracks/submixes/Mix; strips feeding a 5.1 bus
use the 5.1 panner (lanes pan51.x/y/center/lfe stored in MixerStrip::lanes, no schema change);
5.1 strips fold into stereo buses with BS.775; per-channel meters; clip effects on 6 channels.
- file.newSequence {mix, trackType}, sequence.settings {mix}; playback honours the 5.1 Mixdown
Type preference on stereo devices and plays 6 channels on 5.1 devices.
- Export Audio Channels 5.1: WAV WAVE_FORMAT_EXTENSIBLE (mask 0x3F), QuickTime PCM with a chan
atom, AAC channel configuration 6 (reordered to C L R Ls Rs LFE).
- Track Mixer: 5.1 panner puck with Center/LFE, N-channel meters, Show/Hide Tracks, Meter
Input(s) Only; transport record button runs voice-over.
Voice-over: engine AudioInput trait + SyntheticInput, cpal input in the app, audio.voiceover.*
commands (punch-in, pre/post-roll, countdown cues, WAV next to project / scratch disk, one undo
step), track header mic button and Voice-Over Record Settings dialog.
Remix: beat tracking + chroma/cepstra self-similarity planner in audio-dsp, hidden `remix` clip
effect holding the plan, render::remix playback with equal-power crossfades, clip.remix.*
commands, Remix tool and Remix Properties dialog.
Clip Mixer automation: per-track Latch/Touch/Write (clipMixer.setMode/touch/release) heard live
and written as thinned clip Volume/Panner keyframes at the end of the pass.

New L0 crate filmcraft-dnx, written from SMPTE ST 2019-1:2016 + Amd 1:2023
(tables extracted from the standard's text by tools/extract_tables.py).
Decoder: every compression ID (DNxHD 1235-1260 incl. field-coded and
macroblock-adaptive interlace, thin rasters, RGB 4:4:4; DNxHR 1270-1274
LB/SQ/HQ/HQX/444), 8/10/12-bit, 4:2:0/4:2:2/4:4:4, DCT and lossless alpha,
macroblock rows in parallel. Matches ffmpeg within IDCT precision (max 2 LSB,
<=50 per million beyond 1, 87-99% identical) on 22 ffmpeg fixtures; follows
ffmpeg where it departs from the standard's text (reconstruction offset,
CID 1271 weights, 4:4:4 signalling) - documented in the README.
Encoder: DNxHR LB/SQ/HQ/HQX(10/12-bit)/444, CBR at the eq. 7.1 frame sizes,
uniform-qsf binary search + per-macroblock refinement; ffmpeg decodes every
profile with -xerror (HQ luma PSNR 58.8-66.3 dB).
Wiring: MOV AVdn/AVdh import (codec label from the CID), export
Format::DnxHr (MOV AVdh, dnxProfile lb|sq|hq|hqx) in the export dialog and
file.exportMedia.

- model: SequenceSettings::color (ColorPipeline: working space, wide gamut, Auto Tone Map Media;
serde default Rec. 709) and Interpretation::color_space (override; None = metadata)
- render::colorman: source colour space from the override or VUI/colr/MKV metadata, decode tables
(camera log with super-whites, PQ, HLG + OOTF), gamut matrix, tone mapping into SDR working
spaces, gamut mapping; working → SDR monitor transform at the top level
(RenderOptions::working_output keeps working values for HDR export and scopes). Plain Rec. 709
media in a Rec. 709 sequence keeps the old fast path and stays on the GPU; managed layers and
HDR/wide-gamut sequences composite on the CPU
- export: H.264 and ProRes of a PQ/HLG sequence encode BT.2020 PQ/HLG and signal it: VUI / ProRes
header, colr (nclx/nclc), and for PQ mdcv + clli boxes and H.264 SEI (payloadTypes 137/144);
`sdr: true` (and render previews) export tone-mapped SDR. isobmff reads/writes mdcv and clli
- commands: sequence.colorSettings (Sequence ▸ Color Management…), clip.interpretFootage
(Clip ▸ Modify ▸ Interpret Footage…, Project panel context menu), color.spaces,
media.colorInfo; dialogs with automation ids colorDialog.*
- scopes: HDR sequences show a cd/m² waveform on a PQ scale (203 marked) and a BT.2020
vectorscope from the working-space render (scopes.hdrWaveform)
- display-referred wide-gamut input is desaturated into gamut keeping in-gamut colours exactly;
the soft compression is reserved for camera gamuts
- tests: colorman unit tests, engine (interpret/undo, PQ working space values and display),
goldens log_to_rec709 and hdr_tone_map (own renders + sidecars), export PQ/HLG × ProRes/H.264
read back by our demuxer and ffprobe (color_transfer/primaries/space, mastering display and
content light side data), headless UI (dialogs, HDR scopes)
- docs: architecture §5.2 (pipeline, HDR export, display colour management: no macOS EDR yet)

New dev-dependency-only crate crates/testkit (L0, no FilmCraft deps):
FILMCRAFT_FFMPEG/FILMCRAFT_FFPROBE, then PATH (incl. .exe), then known
dirs; SKIPPED lines and FILMCRAFT_REQUIRE_ORACLES=1 to make skips fail;
require_ffmpeg!/require_ffprobe!/require_oracles!; fixtures_dir() under
<workspace>/target/fixtures with per-thread temp names and atomic
generation. Oracle helpers in aac, opus, h264, hevc, h264enc, isobmff,
matroska, prores and export migrated (codecs left on its local lookup).
