+# LibVLCSharp DVD Player Sample
+A cross-platform DVD player sample built with LibVLCSharp and Avalonia UI.
+
+---
+
+## Requirements
+- .NET 10 SDK
+- Avalonia 11.3.12
+- LibVLCSharp 3.9.6
+- LibVLCSharp.Avalonia 3.9.6
+- VideoLAN.LibVLC.Windows 3.0.23 (Windows)
+- VideoLAN.LibVLC.Mac 3.1.3.1 (macOS)
+- **Linux only:** `vlc-plugin-dvd` and `libdvdcss` (required for DVD playback)
+```bash
+sudo pacman -S vlc-plugin-dvd libdvdcss   # Arch Linux
+```
+---
+
+## Test DVD ISO (linux)
+This sample was tested using the **Big Buck Bunny NTSC DVD ISO** — a free and legal open-source film by the Blender Foundation.
+- Download: [Big-Buck-Bunny](https://ia801907.us.archive.org/13/items/BigBuckBunny/big-buck-bunny-NTSC.iso) 
+- Verify ISO: ls -lh ~/big-buck-bunny-NTSC.iso 
+
+### Mount and inspect
+```bash
+sudo mkdir -p /mnt/dvd
+sudo mount -o loop ~/big-buck-bunny-NTSC.iso /mnt/dvd
+ls /mnt/dvd   # should contain VIDEO_TS folder
+```
+
+### Test with system VLC first
+```bash
+vlc dvd:///mnt/dvd
+vlc /mnt/dvd/VIDEO_TS/VTS_01_1.VOB  # or play specific title
+```
+
+### Unmount when done
+```bash
+sudo umount /mnt/dvd
+```
+---
+
+## Test DVD ISO (windows)
+**Prerequisites**
+- [.NET 10 SDK](https://dotnet.microsoft.com/download)
+- No separate VLC installation needed, as `VideoLAN.LibVLC.Windows` NuGet package bundles the native libraries
+
+**Run**
+```bash
+cd LibVLCSharp.DVD
+dotnet run
+```
+
+**DVD Source Options**
+
+- **Physical DVD drive:** `dvd:///D:/` (replace `D` with your drive letter)
+- **ISO file:** right-click the `.iso` in File Explorer → **Mount**, then use the assigned drive letter: `dvd:///E:/`
+- **VIDEO_TS folder:** `dvd:///C:/path/to/VIDEO_TS`
+
+> **Note:** Encrypted commercial DVDs require `libdvdcss`. The NuGet package does not bundle it. Unencrypted ISOs (e.g. Big Buck Bunny) work without it.
+
+---
+
+## Testing on macOS
+
+**Prerequisites**
+- [.NET 10 SDK](https://dotnet.microsoft.com/download)
+- No separate VLC installation needed, as `VideoLAN.LibVLC.Mac` NuGet package bundles the native libraries
+
+**Run**
+```bash
+cd LibVLCSharp.DVD
+dotnet run
+```
+
+**DVD Source Options**
+
+- **Physical DVD drive** — `dvd:///dev/rdisk2` (verify disk number with `diskutil list`)
+- **ISO file** — mount via Finder (double-click) or terminal:
+```bash
+  hdiutil attach ~/your-file.iso
+```
+  Then use `dvd:///Volumes/VOLUME_NAME/` (volume name shown after mount)
+- **VIDEO_TS folder** — `dvd:///path/to/VIDEO_TS`
+
+> **Note:** Encrypted commercial DVDs require `libdvdcss`, installable via Homebrew: `brew install libdvdcss`. Unencrypted ISOs work without it.
+
+---
+
+## Project Setup
+
+### Create the project
+```bash
+dotnet new install Avalonia.Templates
+dotnet new avalonia.app -n LibVLCSharp.DVD
+```
+
+### Add packages
+```bash
+cd LibVLCSharp.DVD # go to the project directory
+dotnet add package LibVLCSharp
+dotnet add package LibVLCSharp.Avalonia
+dotnet add package VideoLAN.LibVLC.Windows
+dotnet add package VideoLAN.LibVLC.Mac
+# don't need of linux nuget package as linux uses system-installed VLC
+```
+
+### Add to solution
+```bash
+cd ~/libvlcsharp-samples # go to the root directory
+dotnet sln libvlcsharp-samples-windows.sln add LibVLCSharp.DVD/LibVLCSharp.DVD.csproj
+dotnet sln libvlcsharp-samples-mac.sln add LibVLCSharp.DVD/LibVLCSharp.DVD.csproj
+```
+
+---
+
+## Run
+```bash
+dotnet run
+```
+> Then click **📂 Open ISO**, select your DVD ISO file and it starts playing.

+## Features

+- DVD ISO file picker
+- Play / Pause
+- Seek via timestamp slider
+- Volume control
+- Minimize, fullscreen and close via custom title bar

+
+## Key Implementation Notes
+
+- `Core.Initialize()` must be called before Avalonia starts in `Program.cs`
+- DVD URI format: `dvd://<absolute-path-to-iso>`
+- `NavigationMode` in LibVLCSharp 3.9.6 has no `Menu` value, so use `Popup` instead, and cast to `(uint)` since `Navigate()` expects `uint`
+- Slider `PointerPressed`/`PointerReleased` must be registered via `AddHandler(..., handledEventsToo: true)` in the constructor — XAML event binding doesn't fire on Slider thumb interaction in Avalonia
+- `Dispatcher.UIThread.Post()` is required when updating the UI from libvlc's `TimeChanged` event since it fires on a background thread
+- On Linux, `vlc-plugin-dvd` must be installed separately — without it DVD ISO playback fails silently
