Hello,

Welcome to our Microsoft Q&A platform!

You should implement this on each platform.

In android, you can refer sample: https://github.com/leye0/XamarinAndroidFFmpeg

And there is a better library here: https://github.com/natario1/Transcoder .

In IOS, try the following code:

        string downloadPath = Environment.GetFolderPath(Environment.SpecialFolder.Personal);  
        string downloadFilePath = Path.Combine(downloadPath, "compressed_video.mp4");  

        var asset = AVAsset.FromUrl( NSUrl.FromFilename( sourceFilePath ) );  


        AVAssetExportSession export = new AVAssetExportSession (asset, AVAssetExportSession.PresetLowQuality );  

        export.OutputUrl = NSUrl.FromFilename( downloadFilePath );  
        export.OutputFileType = AVFileType.Mpeg4;  
        export.ShouldOptimizeForNetworkUse = true;  

        export.ExportAsynchronously(  ( ) =>   
        {  

                if( export.Error != null )  
                    System.Diagnostics.Debug.WriteLine( export.Error.LocalizedDescription );  
        });
