how can I show a video thumbnail from a video path?

Question

I want to show a video thumbnail in an ImageView from a video path on storage. Is there a function that takes a video path and returns a bitmap of a thumbnail? I get the video path by this code:

public ArrayList<String> getAllMedia() {
  HashSet<String> videoItemHashSet = new HashSet<>();
  String[] projection = {MediaStore.Video.VideoColumns.DATA, MediaStore.Video.Media.DISPLAY_NAME};
  Cursor cursor = getContext().getContentResolver().query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, projection, null, null, null);
  try {
    cursor.moveToFirst();
    do {
      videoItemHashSet.add((cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA))));
    } while(cursor.moveToNext());
    cursor.close();
  } catch(Exception e) {
    e.printStackTrace();
  }
  ArrayList<String> downloadedList = new ArrayList<>(videoItemHashSet);
  return downloadedList;
}

Answer 1

It is the default way to create a thumbnail.

For Mini Kind

Bitmap thumb;
//MINI_KIND, size:  512 x 384 thumbnail 
    thumb = ThumbnailUtils.createVideoThumbnail(filePath, MediaStore.Video.Thumbnails.MINI_KIND);
            img_tumbnail.setImageBitmap(thumb);

For Micro Kind

Bitmap thumb;
//MICRO_KIND, size: 96 x 96 thumbnail
thumb= ThumbnailUtils.createVideoThumbnail(filePath, Thumbnails.MICRO_KIND);
img_tumbnail.setImageBitmap(thumb);

Also, you can use Glide for Url as well as Video path of Device.

Glide.with(context).with(this)
                    .asBitmap()
                    .load(videoFilePath) // or URI/path
                    .into(imgView); //imageview to set thumbnail to

also, you can resize thumbnail by using .override(50,50) with Glide.

Answer 2

Use Glide lib

to show thumbnail from local storage

String filePath = "/storage/emulated/0/Pictures/example_video.mp4";

GlideApp  
    .with(context)
    .asBitmap()
    .load(Uri.fromFile(new File(filePath)))
    .into(imageViewGifAsBitmap);
