Android中如何获取视频文件的截图、缩略图

/*** 获取视频文件截图** @param path 视频文件的路径* @return Bitmap 返回获取的Bitmap*/public static Bitmap getVideoThumb(String path) {MediaMetadataRetriever media = new MediaMetadataRetriever();media.setDataSource(path);return media.getFrameAtTime();}/*** 获取视频文件缩略图 API>=8(2.2)** @param path 视频文件的路径* @param kind 缩略图的分辨率：MINI_KIND、MICRO_KIND、FULL_SCREEN_KIND* @return Bitmap 返回获取的Bitmap*/public static Bitmap getVideoThumb2(String path, int kind) {return ThumbnailUtils.createVideoThumbnail(path, kind);}public static Bitmap getVideoThumb2(String path) {return getVideoThumb2(path, MediaStore.Video.Thumbnails.FULL_SCREEN_KIND);}

/*** Bitmap保存成File** @param bitmap input bitmap* @param name output file's name* @return String output file's path*/public static String bitmap2File(Bitmap bitmap, String name) {File f = new File(Environment.getExternalStorageDirectory() + name + ".jpg");if (f.exists()) f.delete();FileOutputStream fOut = null;try {fOut = new FileOutputStream(f);bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fOut);fOut.flush();fOut.close();} catch (IOException e) {return null;}return f.getAbsolutePath();}
