* craft-video: AV1 decoder from FilmCraft (`av1-decode` feature)
FilmCraft's crates/av1 at 4c0d2ad7 becomes craft_video::av1::decode. The encoder moves to
av1/encode and is still exported from craft_video::av1. Feature av1 now turns on av1-decode and
av1-encode, so either half can be built without the other.
The ignored speed tests no longer read the thread CPU clock (FilmCraft used rustix for it).
craft_video::budget (the picture memory budget from DeckCraft's bitstream crate) is added for the
next commit. craft-video is built at opt-level 3 in the dev profile, as FilmCraft built its
codecs.
* craft-video: AV1 decoder hardening from DeckCraft's copy
- The picture store (eight reference slots, the new frame, frames in flight) is checked against
a memory budget before a frame is allocated; Decoder::set_memory_budget.
- Non-uniform tile spacing is refused past MAX_TILE_COLS columns or MAX_TILE_ROWS rows.
* craft-video: AV1 fuzz seeds are 64x64 so SVT-AV1 2.x can encode them
FilmCraft's seeds were 64x48; the SVT-AV1 2.3 on the Ubuntu runners refuses a source under 64
lines, and an encoder that exists but fails is a test failure, not a skip.
* craft-video: MPEG-2 and MPEG-1 video decoder from FilmCraft (`mpeg2`)
FilmCraft's crates/mpeg2v at 4bec22bd moves to craft_video::mpeg2 behind the
decoder-only feature `mpeg2`: sources, README and tests (unit, synthetic
streams checked by ffmpeg, the ffmpeg oracle fixtures, hostile sweeps).
Changes in the move: craft-media-testkit instead of filmcraft-testkit, one
test target (tests/mpeg2), crate paths, rustfmt at this repo's width.
New: a memory budget (Decoder::set_memory_budget, craft_video::budget) checked
when a sequence becomes active, and a mutation test over the synthetic
field-picture, 16x8 and dual-prime streams, which ffmpeg's encoder cannot
produce and the hostile sweep therefore never reached.
* craft-video mpeg2: write the restart check without a negated conjunction (clippy nonminimal_bool)
FilmCraft's crates/apv at 4bec22bd moves to craft_video::apv: the decoder
(craft_video::apv::decode, feature `apv-decode`), the encoder
(craft_video::apv::encode, feature `apv-encode`), both re-exported at the
module root; `apv` turns on both. Sources, README and tests (ffmpeg oracle,
alpha, mutation and hostile sweeps).
Changes in the move: craft_media::bitstream and craft-media-testkit instead of
FilmCraft's, one test target (tests/apv), crate paths.
New: DecodeOptions::memory_budget (craft_video::budget) refuses a frame whose
samples do not fit before anything is allocated (Error::MemoryBudget).
Fixed, each with a test that fails without it (debug-build overflows):
- EncoderConfig::new multiplied width, height and 30 in u64 without a check.
- Frame::new shifted by the bit depth unchecked (32 and above overflow).
- The public transform functions shifted by a bit depth outside 10..=16.
* craft-video: H.264 decoder from FilmCraft (`h264-decode` feature)
FilmCraft's crates/h264 at 4c0d2ad7 becomes craft_video::h264::decode. The encoder moves to
h264/encode and is still exported from craft_video::h264. Feature h264 now turns on h264-decode
and h264-encode, so either half can be built without the other.
Without the threads feature a reference row that was never published read through expect();
it now reads as a gray row. craft_video::budget (the picture memory budget from DeckCraft's
bitstream crate) is added for the next commit. craft-video is built at opt-level 3 in the dev
profile, as FilmCraft built its codecs.
* craft-video: H.264 decoder hardening from DeckCraft's copy
- The picture store (DPB, current picture, pictures in flight or queued for output) is checked
against a memory budget before a picture is allocated; Decoder::set_memory_budget.
- configure_avcc checks every entry before handling any: SPS NAL units in the first list, PPS in
the second. A picture slice in the record starts no picture.
- The inverse transforms clamp coefficients to the spec's r range instead of overflowing.
- Temporal direct motion vectors are scaled in i32 and clipped to the spec range.
- slice_qp_delta is added with a checked add.
- A picture job sets up its picture state inside the panic guard.
* craft-video: HEVC decoder from FilmCraft (`hevc-decode` feature)
FilmCraft's crates/hevc at 4c0d2ad7 becomes craft_video::hevc::decode. The encoder moves to
hevc/encode and is still exported from craft_video::hevc. Feature hevc now turns on hevc-decode
and hevc-encode, so either half can be built without the other.
craft_video::budget (the picture memory budget from DeckCraft's bitstream crate) is added for the
next commit. craft-video is built at opt-level 3 in the dev profile, as FilmCraft built its
codecs.
* craft-video: HEVC decoder hardening from DeckCraft's copy
- The picture store (DPB, current picture, pictures in flight) is checked against a memory
budget before a picture is allocated; Decoder::set_memory_budget.
- configure_hvcc checks every array before handling any NAL: only VPS, SPS, PPS and SEI arrays,
each NAL header agreeing with its array type. A picture slice in the record starts no picture.
- init_qp_minus26, slice_qp_delta and delta_chroma_log2_weight_denom are range checked before
the additions that overflowed on Exp-Golomb values near the i32 limits.
- A picture job sets up its picture state inside the panic guard.
* craft-video: VP9 decoder from FilmCraft (`vp9-decode` feature)
FilmCraft's crates/vp9 at 4c0d2ad7 becomes craft_video::vp9::decode. The encoder moves to
vp9/encode and is still exported from craft_video::vp9. Feature vp9 now turns on vp9-decode and
vp9-encode, so either half can be built without the other.
The decoder's tests find ffmpeg and the fixture directory through craft-media-testkit; a fixture
that cannot be generated fails under CRAFT_MEDIA_REQUIRE_ORACLES=1. craft-video is built at
opt-level 3 in the dev profile, as FilmCraft built its codecs.
* craft-video: VP9 decoder checks its picture store against a memory budget
DeckCraft's copy of the decoder refuses a frame size whose pictures (eight reference slots, the
new frame and those in flight) would not fit a byte budget. The budget type comes with it as
craft_video::budget; FilmCraft's 2^26 luma sample cap stays.
The eight-part craft-video series landed as one commit, because each part's branch contains the parts before it.
