Android: Is it possible to display video thumbnails?

I created a video recording application with library dialog. The library dialog displays the list of recorded videos where each item consists of icon, video title, tags and location information the following way:

Does anyone know whether it is possible to replace icons with video thumbnails (single frame preview)?

Thanks!

Solution 1:

if you don't or cannot go through cursor and if you have only paths or File objects, you can use since API level 8 (2.2) public static Bitmap createVideoThumbnail (String filePath, int kind)

Android documentation

The following code runs perfectly:

Bitmap bMap = ThumbnailUtils.createVideoThumbnail(file.getAbsolutePath(), MediaStore.Video.Thumbnails.MICRO_KIND);

Solution 2:

If you are using API 2.0 or newer this will work.

int id = **"The Video's ID"**
ImageView iv = (ImageView ) convertView.findViewById(R.id.imagePreview);
ContentResolver crThumb = getContentResolver();
BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize = 1;
Bitmap curThumb = MediaStore.Video.Thumbnails.getThumbnail(crThumb, id, MediaStore.Video.Thumbnails.MICRO_KIND, options);
iv.setImageBitmap(curThumb);

Solution 3:

Using the class:

import android.provider.MediaStore.Video.Thumbnails;

We can get two preview thumbnail sizes from the video:

Thumbnails.MICRO_KIND for 96 x 96

Thumbnails.MINI_KIND for 512 x 384 px

This is a code example:

String filePath = "/sdcard/DCIM/Camera/my_video.mp4"; //change the location of your file!

ImageView imageview_mini = (ImageView)findViewById(R.id.thumbnail_mini);
ImageView imageview_micro = (ImageView)findViewById(R.id.thumbnail_micro);

Bitmap bmThumbnail;

//MICRO_KIND, size: 96 x 96 thumbnail
bmThumbnail = ThumbnailUtils.createVideoThumbnail(filePath, Thumbnails.MICRO_KIND);
imageview_micro.setImageBitmap(bmThumbnail);
     
// MINI_KIND, size: 512 x 384 thumbnail 
bmThumbnail = ThumbnailUtils.createVideoThumbnail(filePath, Thumbnails.MINI_KIND);
imageview_mini.setImageBitmap(bmThumbnail);
