MauiMediaRecorderVideoLib

A .NET MAUI library for Android video recording using MediaRecorder with camera preview and stabilization features.

Update: Have resolved issue to do with permssions. Now waits for the user to accept Camera before starting the camera preview. Should now work in Release version of host app. (2Do)
Note also: Audio permissions are not reuqested as not catured. Video only.

• Video recording with MediaRecorder
  • No audio recording

• Camera rotation support (0, 90, 180, 270 degrees)
• Configurable video FPS (30, 60, or default)
• Support for pausing and resuming recording
• Proper handling of Android permissions
• Screen dimensions detection for optimal preview

Usage with a MAUI Android Phone App

Installation

Start by creating a new .NET MAUI project or using an existing one.

Install the package via NuGet:

dotnet add package MauiMediaRecorderVideoLib

Also need to install the following NuGet package:

dotnet add package CommunityToolkit.Maui.Camera

Nb: CommunityToolkit.Maui.Camera is in the library but needs a reference in the App as it uses the Toolkit Peview.

Basic Setup

1. Add the required permissions to your Android Manifest:

<uses-permission android:name="android.permission.CAMERA" />

Note: In app Android//MainActivity calls permissions setup via static method in library that iterates through in-app Android/Manifest permissions.

The following needs updating (2Do).

2. Initialize the video recorder service:

using MauiMediaRecorderVideoLib;

// Initialize the service
var videoRecorderService = new AndroidVideoRecorderService();
await videoRecorderService.InitializeAsync();

3. Start the camera preview:

// Assuming you have a GraphicsView named 'cameraPreview' in your XAML
videoRecorderService.SetPreviewSurface(cameraPreview);

4. Start recording:

// Configure recording options
videoRecorderService.SetVideoFPS(30); // Optional: Set FPS
videoRecorderService.SetImageStabilization(StabilizationMode.Locked); // Optional: Set stabilization

// Start recording

string outputFilePath = Path.Combine(FileSystem.CacheDirectory, "myVideo.mp4");
await videoRecorderService.StartRecordingAsync(outputFilePath);

5. Control recording:

// Pause recording
await videoRecorderService.PauseRecordingAsync();

// Resume recording
await videoRecorderService.ResumeRecordingAsync();

// Stop recording
await videoRecorderService.StopRecordingAsync();

6. Clean up resources:

// Release resources when done
await videoRecorderService.CleanupAsync();

Requirements

• .NET MAUI project targeting Android
