Video Thumbnails in Xamarin Forms

Question

Is there a way to retrieve a thumbnail of a video using Xamarin Forms?

I use the Xam.Plugin.Media plugin to take and pick videos and save them to a specific location. Is it possible to save a thumbnail of the video as well?

//Pick a Video

private async void BtnPick_Clicked(object sender, EventArgs e) { await CrossMedia.Current.Initialize();

        try
        {
            var file = await CrossMedia.Current.PickVideoAsync();
            if (file == null)
                return;
            await StoreVideos(file.GetStream());
        }
        catch (Exception ex)
        {
            Debug.WriteLine(ex.Message);
        }
    }

//Take Video

    private async void BtnTake_Clicked(object sender, EventArgs e)
    {
        var file = await CrossMedia.Current.TakeVideoAsync(new StoreVideoOptions

        {
            Name = "video.mp4",
            Directory = "DefaultVideos",
        });
        await StoreVideos(file.GetStream());

        if (file == null)
            return;
    }

    public async Task<string> StoreVideos(Stream videoStream)
    {
        var storageVideo = await new FirebaseStorage("adam-00000.appspot.com")
            .Child("ProfileVideos")
            .Child(App.UserID + "-" + App.VideoName + ".mp4")

            .PutAsync(videoStream);

        string imgurl = storageVideo;
        return imgurl;
    }

I'm looking to grab the thumbnail of the video, save it and then upload it to Firebase.

No, you do not put [Android.Runtime.Register("android/media/ThumbnailUtils", ApiSince=8, DoNotGenerateAcw=true)] public class ThumbnailUtils : Java.Lang.Objec in you code, you just add this using Android.Media; in your code, Then call this ThumbnailUtils.CreateVideoThumbnail(filePath,kind); method to create Thumbnail of video like this link.https://stackoverflow.com/a/44304943/10627299

Note:This method is just suitable for the android platform, If you use Forms, you should achieve it with dependence service.
