未指定大小的 Android ThumbnailUtils.createVideoThumbnail 在 API 级别 29 中已弃用

Question

public static Bitmap createVideoThumbnail (String filePath, 
                int kind)

The above method is deprecated in API level 29.

We are required to use this now:

public static Bitmap createVideoThumbnail (File file, 
                Size size, 
                CancellationSignal signal)

My question is how can I set the Size to be the native size of the video File that I am creating the thumbnail from ?

I want it to be the same height/width and dimensions .

Before, I could just use ThumbnailUtils.createVideoThumbnail(file_path, MediaStore.Images.Thumbnails.FULL_SCREEN_KIND) ;

Answer 1

Use MediaMetadataRetriever class to get the size. Size will be equal to the size of video file created.

public static Size getThumbSize(String path) {
    MediaMetadataRetriever dataRetriever = new MediaMetadataRetriever();
    dataRetriever.setDataSource(path);
    String width = 
    dataRetriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_WIDTH);
    String height = 
    dataRetriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_HEIGHT);
    return new Size(Integer.parseInt(width), Integer.parseInt(height));
}
