Frequently Asked Questions
Are there any additional installations needed for ROSI?
Official ROSI 5 packages include yt-dlp and FFmpeg. On Windows, macOS, and Linux AppImage builds, yt-dlp uses Deno for full YouTube support. The setup wizard can check for Deno and install it with winget or Homebrew on Windows and macOS when available, or you can install it from the official instructions. On Linux, use your package manager or the official instructions. The Flatpak build includes its own JavaScript runtime, so it does not need Deno. ROSI-LTS has a separate FFmpeg requirement.
How do I upgrade from ROSI 4?
ROSI 4.4.0 and later offer an in-app upgrade to ROSI 5 once ROSI 4 is up to date. If you accept, ROSI downloads and verifies ROSI 5, installs it, removes ROSI 4, and opens ROSI 5, which imports your settings, queue, lifetime stats, and download activity. If the upgrade is not available on your system or fails, ROSI 4 stays installed. You can download ROSI 5 from the ROSI downloads page instead. See the Getting Started guide for system requirements.
What is the difference between the Normal version and LTS version of ROSI?
Main ROSI is the current v5.x line, rebuilt on Tauri, with new features and bundled FFmpeg. ROSI-LTS stays on v3.x with yt-dlp updates and bug fixes, requires system FFmpeg, and is not moving to v4. See About the LTS Version.
Which Linux packages does ROSI 5 provide?
ROSI 5 provides an x64 AppImage and an x64 Flatpak. DEB and RPM packages are no longer published, and Linux ARM64 is not supported in version 5. If you used a ROSI 4 DEB or RPM package, install the AppImage or Flatpak manually.
How do updates work in ROSI 5?
Direct builds check GitHub for updates and can install them in the app. In Settings, choose Auto (follows the installed version), Stable, or Beta. Microsoft Store builds update through the Store. Flatpak builds notify you when an update is available but must be reinstalled from the release page.
Is ROSI available on the Microsoft Store?
Yes. Main ROSI has a Microsoft Store listing. Store packaging and update behavior differ from the direct release packages. ROSI-LTS is distributed through GitHub Releases.
Can I use my own FFmpeg binary?
Yes. Set a custom FFmpeg executable path in Settings to use it instead of the bundled binary.
What does the “Hook into web browser” option do?
The Hook into Web Browser option asks yt-dlp to read cookies from a selected browser profile. This can help when a site requires you to be signed in or applies age checks. Browser availability depends on the operating system and browser support. See About Browser Cookies before enabling it.
What is ROSI’s Privacy Policy?
Read the ROSI Privacy Policy for local processing, yt-dlp connections, updater requests, and preferences.
What are Download Profiles in ROSI?
Download Profiles save quality, format, and output choices for reuse. ROSI includes best-video and audio-only choices, and a custom profile can expose more format settings. See Download Profiles.
Can I drag and drop URLs into the queue?
Yes. Drop one or more URLs into the queue input, review the entries, and start the queue. ROSI supports multi-link intake and queue controls such as reorder, retry, and requeue.
