What it is

YoutubeDownloader is a desktop application (built with Avalonia UI) that downloads videos, playlists, and channels from YouTube in multiple formats and qualities. It uses YoutubeExplode (a reverse-engineered YouTube API client) under the hood to fetch metadata and streams, and FFmpeg to transcode downloaded content into user-preferred formats. The app supports keyword search, quality preferences, and metadata tagging via MusicBrainz integration. Layered architecture: YoutubeDownloader.Core contains domain logic split into Downloading/ (VideoDownloader, FFmpeg wrapper, quality/format preferences), Resolving/ (QueryResolver for playlist/video/channel detection), and Tagging/…

Start here

Open these first:

• YoutubeDownloader/Program.cs — Entry point for the Avalonia application; sets up dependency injection and launches the main window.
• YoutubeDownloader/ViewModels/MainViewModel.cs — Root view model orchestrating dashboard, downloads, and dialog management; core application logic flow.
• YoutubeDownloader.Core/Downloading/VideoDownloader.cs — Core business logic for downloading videos; handles quality selection, file naming, and FFmpeg integration.
• YoutubeDownloader.Core/Resolving/QueryResolver.cs — Resolves YouTube queries (URLs, IDs, playlists) into video metadata; critical for input validation.
• YoutubeDownloader/Services/SettingsService.cs — Manages application configuration, authentication cookies, and user preferences persistence.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/Tyrrrz/YoutubeDownloader.git
cd YoutubeDownloader
dotnet restore
dotnet build YoutubeDownloader.sln
dotnet run --project YoutubeDownloader

Note: FFmpeg must be installed separately (system PATH or bundled).

Daily commands:

dotnet run --project YoutubeDownloader --configuration Release

Or open YoutubeDownloader.slnx in Visual Studio 2022+ and press F5. Requires .NET 8 SDK and FFmpeg on PATH.

Key cautions & unknowns

• Concentrated ownership — top contributor handles 61% of recent commits
• Could not verify tests from the available repository evidence
• 1. FFmpeg dependency: YoutubeDownloader.Core/Downloading/FFmpeg.cs calls System.Diagnostics.Process on 'ffmpeg' binary—must be installed on system PATH or bundled; Windows/macOS/Linux have different binary names.…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
