Answer 2

Below is Kotlin code to get thumbnail from the video path.

fun retrieveVideoFrameFromVideo(videoPath: String?): Bitmap? {
    var bitmap: Bitmap? = null
    var mediaMetadataRetriever: MediaMetadataRetriever? = null
    try {
        mediaMetadataRetriever = MediaMetadataRetriever()
        mediaMetadataRetriever.setDataSource(videoPath, HashMap<String, String>())
        bitmap = mediaMetadataRetriever.frameAtTime
    } catch (e: Exception) {
        e.printStackTrace()
    } finally {
        mediaMetadataRetriever?.release()
    }
    return bitmap
}

Call method as below.

val bm = retrieveVideoFrameFromVideo(model.FilePath)
imgPreview.setImageBitmap(bm)

Hello try this snippet working in my case

        Uri videoUri = data.getData();
        String selectedPathVideo="";
        selectedPathVideo = ImageFilePath.getPath(getApplicationContext(), videoUri);
        Log.i("Image File Path", ""+selectedPathVideo);

        try {
            Bitmap thumb = ThumbnailUtils.createVideoThumbnail(selectedPathVideo, MediaStore.Video.Thumbnails.MICRO_KIND);


            imgFarmerVideo.setImageBitmap(thumb);

        } catch (Exception e) {
            e.printStackTrace();
        }

Without downloading video you can generate thumbnail of video by using below method :

public static Bitmap retriveVideoFrameFromVideo(String videoPath)throws Throwable
{
    Bitmap bitmap = null;
    MediaMetadataRetriever mediaMetadataRetriever = null;
    try
    {
        mediaMetadataRetriever = new MediaMetadataRetriever();
        if (Build.VERSION.SDK_INT >= 14)
            mediaMetadataRetriever.setDataSource(videoPath, new HashMap<String, String>());
            else
                mediaMetadataRetriever.setDataSource(videoPath);
     //   mediaMetadataRetriever.setDataSource(videoPath);
        bitmap = mediaMetadataRetriever.getFrameAtTime(1, MediaMetadataRetriever.OPTION_CLOSEST);
    }
    catch (Exception e)
    {
        e.printStackTrace();
        throw new Throwable("Exception in retriveVideoFrameFromVideo(String videoPath)"+ e.getMessage());
    }
    finally
    {
        if (mediaMetadataRetriever != null)
        {
            mediaMetadataRetriever.release();
        }
    }
    return bitmap;
}

Answer 5

Use android ThumbnailUtils class

  public static Bitmap getThumblineImage(String videoPath) {
    return ThumbnailUtils.createVideoThumbnail(videoPath, MINI_KIND);
  }

Answer 6

To display a bitmap preview of a video, just set the video path of the VideoView and let the stream buffer.

For example:

videoView.setVideoPath("/sdcard/myawesomevideo.mp4");

In a few seconds you will see the first frame of the video.
