A live smoke test of buildArgs' argv against the bundled yt-dlp + ffmpeg found that ffprobe.exe was never bundled (resources/bin/ shipped only ffmpeg.exe). yt-dlp resolves both from --ffmpeg-location, so duration-aware post-processing failed at runtime for every user with "ffprobe not found": --sponsorblock-remove, --force-keyframes-at-cuts, and --split-chapters (CODE-AUDIT C1). - Bundle ffprobe.exe (matching n8.1.2 LGPL build, sha256-verified against the already-bundled ffmpeg.exe) and document it in resources/bin/README.md as a required binary; correct the stale "not committed to git" note. - Guard startDownload against a missing ffmpeg.exe/ffprobe.exe up front so the failure is a clear AeroFetch error, not a cryptic yt-dlp postprocessing one (new getFfprobePath() in binaries.ts). - Expand test/real-download.integration.test.ts from 2 to 8 live cases: crop, sponsorblock-remove, audio opus re-encode, mkv+vp9 merge, subtitle+chapter embed, restrict-filenames, download-archive skip, and Phase C extra-args. All 8 pass against live yt-dlp + ffmpeg. - ROADMAP: mark the Phase A/B/C smoke-test caveats done. CODE-AUDIT: add C1. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Bundled binaries
AeroFetch spawns these from the main process and bundles them via
electron-builder extraResources (they ship outside the asar archive). The
.exe binaries are committed to the repo so a fresh clone builds and runs
without a manual download step.
Drop the three required Windows executables here before running npm run dev or
building; aria2c.exe is optional:
resources/bin/
├── yt-dlp.exe
├── ffmpeg.exe
├── ffprobe.exe
└── aria2c.exe (optional)
yt-dlp.exe
- Download: https://github.com/yt-dlp/yt-dlp/releases/latest
- Grab
yt-dlp.exe. - Unlicense / public domain.
ffmpeg.exe + ffprobe.exe
- Use an LGPL build to keep licensing simple, e.g.
https://github.com/BtbN/FFmpeg-Builds/releases (pick a
*-lgpl-sharedor*-lgplwin64 build) or https://www.gyan.dev/ffmpeg/builds/. - Copy both
ffmpeg.exeandffprobe.exehere — they ship together in the same archive'sbin/folder, and their versions must match. yt-dlp needsffprobe.exeto read media durations; without it, duration-dependent post-processing fails with "ffprobe not found" (--sponsorblock-remove,--force-keyframes-at-cuts, and--split-chaptersall error out). - Ship the LGPL license text alongside the installer before release.
aria2c.exe (optional)
- Powers the "Use aria2c downloader" toggle in Settings → Network for faster multi-connection downloads. If it's missing, that toggle silently falls back to yt-dlp's built-in downloader — nothing breaks.
- Download: https://github.com/aria2/aria2/releases (grab the
aria2-*-win-64bit-build1.zip, copyaria2c.exefrom it here). - GPL-2.0 — ship its license text alongside the installer before release if bundled.
Branding stays generic: AeroFetch is a "yt-dlp frontend." Keep upstream license texts with any distributed build.
