Video Editing

The Video Module SDK delivers a suite of robust video editing tools. These tools facilitate the seamless integration of comprehensive video editing functionalities into your applications, including:

• Video Editing: Modify and enhance video content with precision.

• Concatenation: Easily join multiple video files.

• Merging: Combine video files into a single output.

• Encoding: Convert video files to different formats efficiently.

• Noise Cancellation: Enhance audio quality by removing unwanted background noise.

These features empower developers to create versatile video applications tailored to diverse needs.

Prerequisites

• Ensure you have integrated the TruVideo Core SDK into your project and completed with the authentication process

• Camera module will provide MediaItem or simply provide filepath to upload (optional)

Edit a video

To edit a video, follow these steps:

Step 1 : Import Classes

#if IOS
using TruvideoVideoiOS;
using Foundation;
using UIKit;
#endif

#if ANDROID
using Application = Android.App.Application;
using TruVideoVideoAndroidBinding;
using TruVideoVideoLib = TruVideoVideoAndroid.DotnetTruvideoVideo;
#endif

Step 2 : Init Async Callback Wrapper

#if ANDROID
private Task<T> ExecuteVideoCallbackAsync<T>(Action<VideoCallback> action) {
        var tcs = new TaskCompletionSource<T>();

        action.Invoke(new VideoCallback(
            success => MainThread.BeginInvokeOnMainThread(() =>
                tcs.TrySetResult((T)Convert.ChangeType(success, typeof(T)))),
            failure => MainThread.BeginInvokeOnMainThread(() => tcs.TrySetException(new Exception(failure)))
        ));

        return tcs.Task;
    }
#endif

Step 3 : Call Edit Function

// iOS implementation 
#if IOS
var inputUrl = NSUrl.FromFilename(_filePath);
var outputUrl = NSUrl.FromFilename(_outputPath);
var viewController = UIApplication.SharedApplication.KeyWindow.RootViewController;
TruvideoVideoSdk.Shared.EditVideo(inputUrl, outputUrl, viewController, (resultUrl, error) =>
{
    if (error != null)
    {
        LogTextEditor.Text = $"Error editing video: {error.LocalizedDescription}";
        return;
    }
    LogTextEditor.Text = $"Video edited successfully: {resultUrl}";
});
#endif

// Android implementation
#if ANDROID
string _resultPath = await ExecuteVideoCallbackAsync<string>(cb => TruVideoVideoLib.EditVideo(Application.Context, _inputPath,_outputPath, cb));
LogTextEditor.Text = $"Edit Video: {_resultPath}";
#endif
}

Finalize :

After completing this steps the function should look like

#if IOS
using TruvideoVideoiOS;
using Foundation;
using UIKit;
#endif

#if ANDROID
using Application = Android.App.Application;
using TruVideoVideoAndroidBinding;
using TruVideoVideoLib = TruVideoVideoAndroid.DotnetTruvideoVideo;
#endif

#if ANDROID
private Task<T> ExecuteVideoCallbackAsync<T>(Action<VideoCallback> action) {
        var tcs = new TaskCompletionSource<T>();

        action.Invoke(new VideoCallback(
            success => MainThread.BeginInvokeOnMainThread(() =>
                tcs.TrySetResult((T)Convert.ChangeType(success, typeof(T)))),
            failure => MainThread.BeginInvokeOnMainThread(() => tcs.TrySetException(new Exception(failure)))
        ));

        return tcs.Task;
    }
#endif


private async void Editvideo_OnClicked(object? sender, EventArgs e)
    {
    
// iOS implementation 
#if IOS
var inputUrl = NSUrl.FromFilename(_filePath);
var outputUrl = NSUrl.FromFilename(_outputPath);
var viewController = UIApplication.SharedApplication.KeyWindow.RootViewController;
TruvideoVideoSdk.Shared.EditVideo(inputUrl, outputUrl, viewController, (resultUrl, error) =>
{
    if (error != null)
    {
        LogTextEditor.Text = $"Error editing video: {error.LocalizedDescription}";
        return;
    }
    LogTextEditor.Text = $"Video edited successfully: {resultUrl}";
});
#endif

// Android implementation
#if ANDROID
string _resultPath = await ExecuteVideoCallbackAsync<string>(cb => TruVideoVideoLib.EditVideo(Application.Context, _inputPath,_outputPath, cb));
LogTextEditor.Text = $"Edit Video: {_resultPath}";
#endif
}
