- validateDuration returns 0 instead of NaN when both container is
NaN and scanned is zero
- Use Math.abs for divergence check so container under-reporting is
also corrected (not just over-reporting)
Some containers are truncated when read() has no end bound.
Use container/stream duration + buffer as scan range, matching
the same pattern used in decodeAll().
Two bugs in the export pipeline:
1. Container duration from WebM metadata can be unreliable (Chromium bug
on Linux — reports Infinity, 0, or inflated values). The pipeline
trusted this value, causing inflated exports, frozen video, and
"decode ended early" errors.
Fix: scan actual packet timestamps in loadMetadata() and compare
against container duration. Use packet-based ground truth when they
diverge.
2. The speed-aware audio path (renderPitchPreservedTimelineAudio)
recorded in real-time via MediaRecorder but never paused recording
during trim-region seeks. Seek dead time was captured as audio,
inflating the audio track beyond the video duration.
Fix: pause MediaRecorder during trim seeks, skip past initial trim
before recording starts, wait for seek completion before resuming.
Fixes#276, #433. Partially addresses #428.
gitTracked uses builtins.fetchGit which fails when the source is
already a store path (happens with path: flake inputs from consuming
flakes). Detect store paths at eval time and fall back to cleanSource.
Replace denylist approach with gitTracked to exclude node_modules,
dist, .git, and any other untracked artifacts from the derivation.
Keeps the nix/flake/md exclusions as they are nix-only or non-source.
Reproducible development environment for NixOS/Nix contributors:
- Dev shell with Node 22, system Electron, Playwright, LD_LIBRARY_PATH
for X11/Wayland/audio libs, activated automatically via direnv
- buildNpmPackage derivation wrapping system Electron with desktop file
and hicolor icons
- NixOS module (programs.openscreen.enable) with xdg-desktop-portal
- Home Manager module for per-user installation
- Overlay for composing with other flakes
Tested: nix flake show, nix develop, nix build, nixos-rebuild switch
- derive available locales from locale folders with required namespace validation
- exclude incomplete locales and report missing namespace files
- align system-language suggestion and selectors with discovered locales
- improve launch HUD language menu interaction, scrolling, and viewport clipping
- make i18n-check discover locale folders automatically
