What it does
Libvlc is an agent skill from managedcode/dotnet-skills. 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.
Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `libvlc-skill.md` and `manifest.json`). Compatibility notes: .NET 6+, .NET Standard 2.0+, .NET Framework 4.6.1+
It sits in Development, covering Codebase knowledge for agents. The repository describes itself as: Installable .NET skill catalog and CLI for Codex, Claude Code, GitHub Copilot, and Gemini. The licence is MIT.
When your agent uses it
- Helping with LibVLC
- LibVLCSharp for media playback
- : LibVLC Skill implementation
- Documentation work
Example prompts
- “/libvlc”
Requirements
- Compatibility (from SKILL.md): .NET 6+, .NET Standard 2.0+, .NET Framework 4.6.1+
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- 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.
What it can do on your machine
Read from SKILL.md and the folder at commit 535dd55. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
.NET 6+, .NET Standard 2.0+, .NET Framework 4.6.1+
From compatibility in the SKILL.md frontmatter.
Context cost
Libvlc loads about 826 tokens when it runs. Until then it costs about 131 tokens; SKILL.md has 345 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

LibVLC Skill
You are an expert assistant for developers using libvlc (both 3.x and 4.x), the multimedia framework behind VLC media player. You help with API usage, code generation, debugging, and architecture decisions across all supported languages and platforms.
Version markers
Throughout the reference, inline markers indicate version-specific APIs:
- No marker — same in both 3.x and 4.x
[3.x]— only in libvlc 3.x (removed in 4.x)[4.x]— new in libvlc 4.x[4.x change]— exists in both but signature changed
When generating code, ask the user which version they target if not already clear from context.
Reference
For complete API signatures, code examples, language bindings, platform integration, streaming recipes, troubleshooting, and migration guidance, see libvlc-skill.md.
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
- §2 Core Concepts — lifecycle, threading rules, event system, error handling, logging, plugin discovery
- §3 API Reference — instance, media, media player, media list, events, dialog, discoverer, renderer, VLM, tracklist, program, GPU rendering, A-B loop, picture API
- §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
