如何在Android中获取视频的缩略图

问题描述

我需要一些帮助来创建从我的android手机录制的视频的缩略图，我从此链接，我修改了代码的这一部分以生成缩略图，但是由于某种原因未生成缩略图，因此将不胜感激.

I want some help in creating thumbnail of a video being recorded from my android phone and I got this code from this Link, and I modified this part of the code to generate the thumbnail but somehow the thumbnail is not being generated, so any help will be appreciated.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (resultCode == RESULT_OK && requestCode == VIDEO_CAPTURED) {
        videoFileUri = data.getData();
        if (videoFileUri != null) {
           Bitmap image= ThumbnailUtils.createVideoThumbnail(videoFileUri.toString(),MODE_APPEND);

 ImageView imageView=(ImageView)findViewById(R.id.image);
 imageView.setImageBitmap(image);
        }

        playVideoButton.setEnabled(true);
    }
}

推荐答案

您可以使用glide.其自动设置的视频缩略图.

You can use glide. its automatically set thumb image of video.

Glide还可以显示视频的缩略图，只要它们存储在手机中即可.让我们假设您通过让用户选择视频来获取文件路径:基于此文档 https://futurestud.io/tutorials/glide-displaying-gifs-and-视频

Glide is also able to display the thumbnail of videos, as long as they're stored on the phone. Let's assume you get the file path by letting the user select a video: Based on this document https://futurestud.io/tutorials/glide-displaying-gifs-and-videos

String filePath = "/storage/emulated/0/Pictures/example_video.mp4";

Glide
    .with(context)
    .asBitmap()
    .load(Uri.fromFile(new File(filePath)))
    .into(imageViewGifAsBitmap);
