What this adds

A film format, webm - AV1 video in WebM, no sound, at the exact size asked for like every other format. Its length is independent of its size: a one hour film at 30 fps is 977 128 B at the smallest, because after the first frames every frame shows an already coded picture again in three bytes.

A new kind of setting, a length of time - duration and keyframe_interval take 10s, 1m30s, 1h, 500ms, 59.9s, counted in whole milliseconds. A bare number and a length that is not a whole millisecond are refused rather than guessed or rounded.

How

  • internal/format/video - shared by WebM now and MP4 next. gav1d codes still pictures only, so the package keeps its tile data and writes a full sequence header and the frame headers itself, reading gav1d's output by the specification and refusing any shape it cannot re-wrap.
  • One stream shape: a shown key frame, a hidden intra-only copy of the same picture, then show_existing_frame of the copy. A shown key frame may not be shown again - libaom refuses that stream, while gav1d's decoder, Chromium and libdav1d inside ffmpeg accept it, so none of those is used as a witness.
  • Colour converted to BT.709 studio range in whole numbers and declared in the stream and the container. The AV1 level is the lowest Annex A allows, chosen after the picture is coded.
  • internal/format/webm - EBML written as a stream with no allocation per frame, SeekHead, Cues at every key frame, and a Void at the end that carries the padding, so every size above the minimum is reachable.
  • Planning stays arithmetic: per cluster, never per frame, at most 100 000 key frames, and a 16:9 picture ladder whose ceilings were measured across seeds and every label length.
  • A length that does not end on a frame is refused with the two nearest that do.

Witnesses

  • New oracle libaom (ffmpeg): judged by what ffmpeg prints, because its exit code differs between ffmpeg versions and a cut WebM ends 0, and it reports the frames decoded. The CI oracle job's apt ffmpeg has libaom, so no workflow change.
  • strict.py reads a WebM without this program's code: segment covers the file, Void last, SeekHead points where it says, whole OBUs, no picture shown that may not be, Cues equal the key frames.
  • New guards in film_test.go: the show rule read back from the file, frames and duration equal to the manifest, the level against the specification's own examples, the refusal of a length that is not on a frame, and every frame decoded by libaom. Three pinned byte cases.

Changed

  • empty-and-minimal ejects one target more (a film), so the recipe_hash of a run of it with formats at all differs. No generated file changes. Recorded as Changed, no major.

Not done in this PR

  • Opening the films in VLC, Films & TV, Firefox and Edge (the fidelity checklist row stays PENDING). Chromium was checked: plays, exact duration, seeks.
  • The social preview image changed (27 formats) and has to be uploaded to GitHub by hand.
  • MP4 follows on the same video package.

… 500ms, in whole milliseconds

The first step towards video. A duration setting is written the way a
person writes one and counted in whole milliseconds. A bare number is
refused rather than read as seconds, a length that is not a whole
millisecond is refused rather than rounded, and the arithmetic runs on the
digits, so 0.025h is exactly 90 000 ms.

The refusal and the sentence under an empty field are one phrase, the
window draws the setting as a short box, and the control catalogue shows
it. Both the window's sentences and the engine's refusals are in Polish.
No format declares one yet.

Property.Allows moved its whole number branch into allowsInt, because one
more kind inline took it into the band the branching guard watches.

A new shared package, internal/format/video, holds what a film is: the
timeline, one picture with the label, and the AV1 stream. gav1d codes still
pictures only, so the package keeps its tile data and writes the sequence
header and the frame headers itself. The stream has one shape - a key frame,
a hidden copy of the same picture, and every other frame showing the copy
again in three bytes - because a shown key frame may not be shown twice and
libaom refuses a stream that does.

webm is the container: EBML written as a stream, a SeekHead, Cues at every
key frame, and a Void at the end that carries the padding, so every size
above the minimum is reachable. Planning is arithmetic over clusters, never
over frames, and a picture is chosen from a ladder whose ceilings were
measured across seeds and every length of label.

The colour is BT.709 studio range, converted in whole numbers and said in
both the stream and the container. The level is the lowest the AV1
specification allows, chosen after the picture is coded.

A new oracle, libaom through ffmpeg, judges a film by what ffmpeg prints
rather than its exit code, and reports how many frames it decoded. The
structural checker reads a WebM without this program's code.

Full details: Safe File Parsing

Explanation

The new check_webm reader can crash on malformed EBML. It is registered as the webm check and the CLI passes file bytes to it. An empty Segment produces children == [], then children[-1] raises IndexError instead of reporting a parse failure. A short SimpleBlock can also trigger unchecked indexing at data[cb] or data[cb + 3].

Resolution

Harden check_webm before each indexed read. Reject an empty Segment, validate required SeekHead fields, and require each SimpleBlock to contain its track number, timestamp, and flags before reading those fields. Route malformed structures through fail() so the checker reports a controlled failure instead of raising an uncaught exception.

[warning] 170-170: A log/format call (log.Print/Printf/Println, the Fatal/Panic variants, fmt.Sprintf, or a structured logger's Info/Warn/Error/Debug method) is given a message built by concatenating a string literal with a non-literal value such as request data. Unsanitized, attacker-controlled input written to logs enables log forging / CRLF injection: an attacker can inject newlines to spoof log entries or break log parsers. Do not concatenate raw input into the log message; pass it as a separate structured field/argument (e.g. 'log.Printf("user: %s", user)' or 'logger.Info("login", "user", user)') and strip or escape newline characters first.
Context: t.Errorf("an empty field says %q, expected %q", got, want+", default 10s")

…ng, the film guard checks the height, the README stops spelling the count

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…e-tile limit reaches the catalogues, the site and the changelog

check_webm in strict.py raised on an empty segment, a Seek without its ID or
position, and a block before its cluster's Timestamp, and misread a
SimpleBlock shorter than four bytes. Each is now a FAIL with its reason, and
an OBU size over the eight bytes AV1 allows is refused too.

The width limit of 4096 and the new joint reason are in both catalogues with
their Polish text, the new refusal for a picture over one tile is in Polish,
and the formats page in every language shows the width up to 4096.
