我的Android进阶之旅------>使用ThumbnailUtils类获取视频的缩略图

Androidamp 获取 视频 之旅 进阶 gt ------&
2023-09-27 14:29:23 时间


今天看了一段代码，是关于获取视频的缩略图的，让我认识了一个ThumbnailUtils类，代码如下。

Bitmap bitmap = ThumbnailUtils.createVideoThumbnail(path, Thumbnails.MINI_KIND); //用于获取视频的缩略图

BitmapDrawable background=new BitmapDrawable(bitmap);


通过察看android.media.ThumbnailUtils的源码，可以发现该类提供了三种静态方法可以直接调用获取，从而可以帮助我们获取系统视频或图片文件的缩略图。


第一个方法可以用来创建一张视频的缩略图，如果视频已损坏或者格式不支持可能返回null

 /**

 * Create a video thumbnail for a video. May return null if the video is

 * corrupt or the format is not supported.

 * @param filePath the path of video file

 * @param kind could be MINI_KIND or MICRO_KIND

 public static Bitmap createVideoThumbnail(String filePath, int kind) {

 Bitmap bitmap = null;

 MediaMetadataRetriever retriever = new MediaMetadataRetriever();

 try {

 retriever.setDataSource(filePath);

 bitmap = retriever.getFrameAtTime(-1);

 } catch (IllegalArgumentException ex) {

 // Assume this is a corrupt video file

 } catch (RuntimeException ex) {

 // Assume this is a corrupt video file.

 } finally {

 try {

 retriever.release();

 } catch (RuntimeException ex) {

 // Ignore failures while cleaning up.

 if (bitmap == null) return null;

 if (kind == Images.Thumbnails.MINI_KIND) {

 // Scale down the bitmap if its too large.

 int width = bitmap.getWidth();

 int height = bitmap.getHeight();

 int max = Math.max(width, height);

 if (max 512) {

 float scale = 512f / max;

 int w = Math.round(scale * width);

 int h = Math.round(scale * height);

 bitmap = Bitmap.createScaledBitmap(bitmap, w, h, true);

 } else if (kind == Images.Thumbnails.MICRO_KIND) {

 bitmap = extractThumbnail(bitmap,

 TARGET_SIZE_MICRO_THUMBNAIL,

 TARGET_SIZE_MICRO_THUMBNAIL,

 OPTIONS_RECYCLE_INPUT);

 return bitmap;


参数说明：


kind表示类型，可以有两个选项，分别是Images.Thumbnails.MICRO_KIND和Images.Thumbnails.MINI_KIND，其中，MINI_KIND: 512 x 384，MICRO_KIND: 96 x 96,当然读了代码你会发现，你也可以传入任意的int型数字，只是就不会对获取的bitmap进行相关的设置，我们可以自己使用extractThumbnail( Bitmap source, int width, int height)方法对返回的bitmap进行相关设置。

Bitmap source, int width, int height) { return extractThumbnail(source, width, height, OPTIONS_NONE); }
参数说明：


* @param height targeted height * @param options options used during thumbnail extraction public static Bitmap extractThumbnail( Bitmap source, int width, int height, int options) { if (source == null) { return null; float scale; if (source.getWidth() source.getHeight()) { scale = width / (float) source.getWidth(); } else { scale = height / (float) source.getHeight(); Matrix matrix = new Matrix(); matrix.setScale(scale, scale); Bitmap thumbnail = transform(matrix, source, width, height, OPTIONS_SCALE_UP | options); return thumbnail; }



参数说明：
options表示在缩略图抽取时提供的选项，如果options定义为OPTIONS_RECYCLE_INPUT,则回收@param source这个资源文件(除非缩略图等于@param source)

* 此方法有两点好处： * 1. 使用较小的内存空间，第一次获取的bitmap实际上为null，只是为了读取宽度和高度， * 第二次读取的bitmap是根据比例压缩过的图像，第三次读取的bitmap是所要的缩略图。 * 2. 缩略图对于原图像来讲没有拉伸，这里使用了2.2版本的新工具ThumbnailUtils，使 * 用这个工具生成的图像不会被拉伸。 * @param imagePath 图像的路径 * @param width 指定输出图像的宽度 * @param height 指定输出图像的高度 * @return 生成的缩略图 private Bitmap getImageThumbnail(String imagePath, int width, int height) { Bitmap bitmap = null; BitmapFactory.Options options = new BitmapFactory.Options(); options.inJustDecodeBounds = true; // 获取这个图片的宽和高，注意此处的bitmap为null bitmap = BitmapFactory.decodeFile(imagePath, options); options.inJustDecodeBounds = false; // 设为 false // 计算缩放比 int h = options.outHeight; int w = options.outWidth; int beWidth = w / width; int beHeight = h / height; int be = 1; if (beWidth beHeight) { be = beWidth; } else { be = beHeight; if (be = 0) { be = 1; options.inSampleSize = be; // 重新读入图片，读取缩放后的bitmap，注意这次要把options.inJustDecodeBounds 设为 false bitmap = BitmapFactory.decodeFile(imagePath, options); // 利用ThumbnailUtils来创建缩略图，这里要指定要缩放哪个Bitmap对象 bitmap = ThumbnailUtils.extractThumbnail(bitmap, width, height, ThumbnailUtils.OPTIONS_RECYCLE_INPUT); return bitmap; /** * 获取视频的缩略图 * 先通过ThumbnailUtils来创建一个视频的缩略图，然后再利用ThumbnailUtils来生成指定大小的缩略图。 * 如果想要的缩略图的宽和高都小于MICRO_KIND，则类型要使用MICRO_KIND作为kind的值，这样会节省内存。 * @param videoPath 视频的路径 * @param width 指定输出视频缩略图的宽度 * @param height 指定输出视频缩略图的高度度 * @param kind 参照MediaStore.Images.Thumbnails类中的常量MINI_KIND和MICRO_KIND。 * 其中，MINI_KIND: 512 x 384，MICRO_KIND: 96 x 96 * @return 指定大小的视频缩略图 private Bitmap getVideoThumbnail(String videoPath, int width, int height, int kind) { Bitmap bitmap = null; // 获取视频的缩略图 bitmap = ThumbnailUtils.createVideoThumbnail(videoPath, kind); System.out.println("w"+bitmap.getWidth()); System.out.println("h"+bitmap.getHeight()); bitmap = ThumbnailUtils.extractThumbnail(bitmap, width, height, ThumbnailUtils.OPTIONS_RECYCLE_INPUT); return bitmap; }
