How to create a video preview in android?

Question

I have a video file in my sdcard. I would like to show a preview of this video in my ImageView . Please let me know how to do this in Android. Thank you for your help and time.

Answer 1

If you use API level 8 and above. You can create preview of a video like this:

String videoFile = "/sdcard/blonde.mp4";
Bitmap thumbnail = ThumbnailUtils.createVideoThumbnail(videoFile,
        MediaStore.Images.Thumbnails.MINI_KIND);

Now you can show it in an ImageView:

ImageView imageView = (ImageView) findViewById(R.id.my_image_view);
imageView.setImageBitmap(thumbnail);

Or you can set it to a VideoView as a background, so that it is shown as a first video frame before the video starts playing:

VideoView video = (VideoView) findViewById(R.id.my_video_view);
BitmapDrawable bitmapDrawable = new BitmapDrawable(thumbnail);
video.setBackgroundDrawable(bitmapDrawable);

Answer 2

This example works for blonde.mp4 file:

String videoFile = "/sdcard/blonde.mp4";
Bitmap thumbnail = ThumbnailUtils.createVideoThumbnail(videoFile, MediaStore.Images.Thumbnails.MINI_KIND);
