    no cross platform solutions available i think.

    for android ,

    compress the video using ffmpeg for tamarin android https://github.com/leye0/XamarinAndroidFFmpeg

    for iOS,

    use below 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 );
                });`

    Hi,

    used the video compression process with the below comments, it works for up to Nougat 7.0 (API level 24), After the Android version doesn't work. Kindly help me on this.
    string[] cmds = new string[] {
    "-y",
    "-i",
    inputFilepath,
    "-strict", "experimental",
    "-vcodec", "libx264",
    "-preset", "ultrafast",
    "-crf","30", "-acodec","aac", "-ar", "44100" ,
    "-q:v", "20",
    "-vf",
    "mp=eq2=1:1.68:0.3:1.25:1:0.96:1",
    ouputFile,
    };
    Has anyone had this same problem and has a solution?

    Can you share the sample code to reduce the video resolution so that I can upload to server. I am struggling with this. Any help is appreciated.
