套件介紹

根據套件公開資料產生的選型評估,僅供參考。

一個輕量級的 Flutter 套件,用於影片處理,讓開發者能直接從 Dart 程式碼中壓縮影片、移除音訊軌道並產生縮圖。專為 Android、iOS 和 macOS 上的高效多媒體處理而設計,無需原生平台程式碼即可簡化常見的影片處理任務。非常適合需要設備端影片優化與預覽產生的應用。

適用情境

  • 壓縮大型影片檔案以節省儲存空間
  • 從影片中移除音訊
  • 從影片檔案產生縮圖
  • 優化影片以上傳
  • 即時處理影片
  • 透過壓縮媒體減少應用程式大小

主要特色

  • 影片壓縮支援
  • 音頻移除功能
  • 縮圖提取
  • 跨平台相容性
  • 簡單的 Dart API
  • 輕便且快速

適合對象

  • 媒體密集型應用
  • 影片分享平台
  • 內容創作工具
  • 帶有影片上傳的行動應用程式
  • 需要離線視頻處理的應用
  • 尋求最小原生代碼的開發者

使用建議

  • 需要原生平台權限
  • 可能影響低端裝置的效能
  • 僅限基本影片操作
  • 依賴於底層原生庫
  • 不適合複雜的影片編輯
  • 檔案大小的減少取決於來源品質

video_compress

Compress videos, remove audio, manipulate thumbnails, and make your video compatible with all platforms through this lightweight and efficient library. 100% native code was used, we do not use FFMPEG as it is very slow, bloated and the GNU license is an obstacle for commercial applications. In addition, google chrome uses VP8/VP9, safari uses h264, and most of the time, it is necessary to encode the video in two formats, but not with this library. All video files are encoded in an MP4 container with AAC audio that allows 100% compatibility with safari, mozila, chrome, android and iOS.

Works on ANDROID, IOS and desktop (just MacOS for now).

Lets Get Started

1. Depend on it

Add this to your package's pubspec.yaml file:

dependencies:
  video_compress: ^3.1.0
2. Install it

You can install packages from the command line:

with pub:

$  pub get
3. Import it

Now in your Dart code, you can use:

import 'package:video_compress/video_compress.dart';

How to use

Imports
import 'package:video_compress/video_compress.dart';
    

Video compression

MediaInfo mediaInfo = await VideoCompress.compressVideo(
  path,
  quality: VideoQuality.DefaultQuality, 
  deleteOrigin: false, // It's false by default
);

Check compress state

VideoCompress.isCompressing

Get memory thumbnail from VideoPath

final uint8list = await VideoCompress.getByteThumbnail(
  videopath,
  quality: 50, // default(100)
  position: -1 // default(-1)
);

Get File thumbnail from VideoPath

final thumbnailFile = await VideoCompress.getFileThumbnail(
  videopath,
  quality: 50, // default(100)
  position: -1 // default(-1)
);

Get media information

final info = await VideoCompress.getMediaInfo(videopath);

delete all cache files

  • Delete all files generated by this will delete all files located at 'video_compress', you shoule ought to know what are you doing.
await VideoCompress.deleteAllCache()

Listen the compression progress

class _Compress extends State<Compress> {

  Subscription _subscription;

  @override
  void initState() {
    super.initState();
    _subscription =
        VideoCompress.compressProgress$.subscribe((progress) {
      debugPrint('progress: $progress');
    });
  }

  @override
  void dispose() {
    super.dispose();
    _subscription.unsubscribe();
  }
}
TODO
  • Add the trim video function
  • Add cancel function to Android
