av-tools/CHANGELOG.md

Changelog

All notable changes to av-tools are documented here. The project follows semantic versioning once a first release is legally publishable.

0.3.0 — 2026-07-27

• Make imported media and browser-native duration/dimensions available without loading FFmpeg, so recognized files can start playback immediately.
• Move authoritative codec, stream, chapter and tag inspection to explicit or operation-driven demand; keep playback usable after inspection failure and expose bounded retry controls.
• Inspect automatically when Quick Convert, preview proxies, timeline renders or advanced tools require authoritative details, while preserving deterministic multi-file timeline order.
• Recover Firefox probes with a fresh same-mode core, safe MT-to-ST fallback and operation reservations that prevent concurrent mounts or preference changes.
• Add Chromium and Firefox evidence proving the supplied 153 MB, 43-minute lecture plays before detailed inspection and retains the same media element afterward.

0.2.1 — 2026-07-27

• Move the canonical source, manifest schema links, and package registry from the personal zemion namespace to the lotobo (LocalToolBox) Gitea organization.
• Upgrade the Toolbox contract, React shell, and validation testkit to 0.2.3, republished from the organization-owned registry without functional shell changes.
• Replace the generic starter favicon with original add·ideas audio/video file artwork.

0.2.0 — 2026-07-27

• Allow recognized local audio/video to begin native browser playback while FFmpeg inspection continues in the background.
• Replace the fixed 30-second media-inspection watchdog with a bounded, size-aware budget and report timeout expiry separately from user cancellation.
• Add an isolated, reproducible Chromium ST/MT Opus regression harness using the reviewed cores, checked tone fixture and real built-in command plan.
• Rebuild ST/MT core 0.12.10 with the upstream 5 MiB stack fix, lock and deterministically package the exact assets, pass non-empty Opus encode and re-probe in both modes, and enable Opus presets behind runtime capabilities.
• Add bounded 0.04–10 second audio/video crossfades to normalized sequential joins, including runtime xfade/acrossfade gates and clip-material checks.
• Add bounded scene-change analysis and exact-PTS thumbnail/contact-sheet extraction, with an honest no-scenes result instead of silent substitution.
• Bundle unmodified DejaVu Sans 2.37 with byte identity, upstream archive provenance and full terms; verify it in-browser before labelled contact sheets and fail closed when drawtext is unavailable.
• Add native execution coverage, pinned-core browser matrix steps and an opt-in large-file browser playback-during-inspection evidence run.
• Make removal of queued or active source inspections generation-safe, cancel owned active probes and prevent stale results from updating deleted or same-ID replacement assets.

0.1.0 — 2026-07-24

• Scaffold a local-first React/Vite audio and video toolbox application.
• Integrate Toolbox SDK 0.2.2 for standalone and Toolbox-context operation.
• Self-host exact ffmpeg.wasm single-thread and multithread core 0.12.10 assets; add capability detection and single-thread fallback.
• Add typed media, project, command-plan and preset foundations for conversion and light sequential editing.
• Wire the Edit workspace to fast and accurate trim plus compatibility-checked fast concat and preset-backed normalized concat with an explicit missing-audio policy.
• Add a bounded in-memory application queue for eight scheduled operations, with one FFmpeg execution at a time, progress, cleanup, cancellation and recovery behavior.
• Bound long-session native heap retention by refreshing the idle ffmpeg.wasm core before its seventeenth media execution, before a fourth contact sheet, and after a bare core abort, without discarding queued work or completed results.
• Add configurable bounded preview proxies and reuse matching derivatives from the local cache.
• Add storage, waveform, inspection, timeline, project, result verification and export workflows.
• Add deterministic generated AV fixtures, deployment examples, security and architecture documentation, deterministic release packaging and a temporary Toolbox Portal assembly smoke.
• Record a 2026-07-24 local Vitest result of 303 passing tests and one conditional native subtitle-filter skip.
• Exercise the real pinned ST core in Chromium across a broad conversion, structural-editing, analysis, image, metadata, chapter, subtitle, queue and recovery matrix; verify a real MT H.264/AAC conversion and MT-to-ST fallback.
• Record a pinned ST/MT Chromium performance baseline for 2-second 160×90 and 6-second 640×360 H.264/AAC inputs. This is a one-run workstation baseline, not a universal performance claim.
• Record the pinned-core runtime inventory: 341 demuxers, 173 muxers, 515 decoders, 204 encoders and 465 filters (1,698 entries).
• Verify the checksums and native probes for all 15 generated CC0 fixtures.

Release assets

• Identify the exact reviewed GPL-3.0-or-later source with the annotated v0.1.0 tag.
• Distribute the reviewed Corresponding Source and third-party notices for the GPL-enabled FFmpeg cores and linked codecs beside the binary. The x264 and LAME branch inputs are pinned to immutable commits in SOURCE.md.
• Browser feature/format claims beyond the recorded Chromium ST matrix and narrow MT H.264/AAC evidence require cross-browser and exhaustive MT runs.
• Mobile and cross-browser performance is unrecorded; the Chromium workstation baseline needs cold-cache repetitions and statistical ranges.
