The Linux release ffmpeg is built statically from source, and ffmpeg only
autodetects --enable-vaapi when libva headers are present at configure time.
Neither build path installed them, so every release shipped a static ffmpeg
with no h264_vaapi encoder -- the zero-copy export silently fell back to
software 100% of the time.
- Containerfile + build.yml: install libva-dev + libdrm-dev so the from-source
ffmpeg gets VAAPI.
- build.yml: assert the release binary links libva, so a missing dep can't
silently regress to a software-only build again.
- deb/rpm: libva (libva2/libva-drm2/libdrm2, libva/libdrm) is a hard runtime
dep -- the vaapi-enabled ffmpeg DT_NEEDEDs it, so the app won't launch
without it. The VA driver is a soft recommends (absent it, export falls back
to software): va-driver-all (deb), intel-media-driver/mesa-va-drivers (rpm).
build.rs needs no change: releases link ffmpeg statically (its bundling path
is skipped) and the AppImage is thin, taking libva from the host like libvulkan.
The shipping product is the pure-Rust app in lightningbeam-ui/; the old
JavaScript UI in src/ is browser-only (window.__TAURI__ is shimmed by
src/tauri_polyfill.js), so the src-tauri Tauri backend is dead. It also no
longer compiled (mid-refactor: missing video_server module, handler list
referencing deleted commands), and CI only ever built lightningbeam-ui.
- Delete src-tauri/ entirely (commands, native renderer/render-window,
websocket frame streamers, Tauri config, generated schemas, icons).
- Relocate icon.icns into lightningbeam-ui/lightningbeam-editor/assets/icons/
(the only src-tauri asset still needed) and repoint the editor's window-icon
include_bytes! at assets/icons/256x256.png (was src-tauri/icons/icon.png).
- CI/packaging: drop the redundant icon-copy steps (PNGs are committed in the
editor assets) and point macOS bundling at the relocated icns.
- package.json: drop @tauri-apps/* deps and the tauri script.
- Docs/.gitignore: drop src-tauri references.
daw-backend/ (shared audio engine) and the top-level WASM lightningbeam-core/
are untouched. Editor builds clean.
