LibVLC Skill
Expert knowledge of the libvlc C API (3.x and 4.x), the multimedia framework behind VLC media player. Use when helping with LibVLC or LibVLCSharp for media playback, streaming, or transcoding. USE FOR: LibVLC Skill implementation, review, migration, debugging, or documentation work. DO NOT USE FOR: unrelated stacks; generic tasks that do not need this specific guidance. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when changes are made.
Workflow
- Confirm whether the target is libvlc 3.x or 4.x, then choose APIs and bindings that match that version.
- Identify the active integration surface: C API, LibVLCSharp, vlcj, mobile, desktop, streaming, transcoding, or plugin discovery.
- Load libvlc-skill.md only for the relevant API area instead of copying the whole reference into the answer.
- Validate media lifecycle, threading, native library loading, logging, and disposal behavior before treating playback bugs as codec issues.
Validate
- the libvlc major version is explicit
- native libraries and plugins are discoverable in the target runtime
- event callbacks do not block libvlc worker threads
- media, player, and instance objects are disposed in the correct order
Sections in the reference:
- §1 Architecture Overview — pipeline, object model, single-instance rule

- §4 Language Bindings — C, C#/LibVLCSharp, Python, Java/vlcj, Go, C++/libvlcpp
- §5 Common Workflows — playback, metadata, thumbnails, playlists, Chromecast, transcoding, streaming, recording, track selection, mosaic, mobile lifecycle
- §6 Platform Integration — Windows (Win32, WPF, WinForms, D3D11), macOS/iOS, Linux (GTK, wxWidgets), Qt, Android, Avalonia
- §7 Streaming & Transcoding — sout chains, protocols, Chromecast
- §8 Troubleshooting — deadlocks, no audio/video, memory leaks, common pitfalls
- §9 CLI Options
- §10 Deprecated APIs
- §13 Migration Guide (3.x → 4.x) — signature changes, removed APIs, new APIs, type changes
