flutter_video_caching is a powerful flutter plugin for caching video. It can be use with video_player package. It supports formats like m3u8 and mp4, play and cache videos simultaneously, precache the video before playing.

Features #

• Multi-format support: supports common video formats such as m3u8 (HLS) and MP4
• Memory and file cache: implements LRU (least recently used) memory cache strategy, combined with local file cache to reduce network requests
• Pre-caching mechanism: supports downloading video clips in advance to improve the continuous playback experience
• Background download: uses Isolate to achieve multi-task parallel download without blocking UI threads
• Priority scheduling: supports setting priorities for download tasks and optimizes resource allocation

Getting started #

dependencies:
  flutter_video_caching: 0.1.3

Usage #

1. Init video proxy #

import 'package:flutter_video_caching/flutter_video_caching.dart';

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  VideoProxy.init();
  runApp(const HomeApp());
}

2. Use with video_player #

playControl = VideoPlayerController.networkUrl(url.toLocalUri());

3. Precache video #

VideoCaching.precache(url);

4. Use in PageView #

PageView.builder(
  controller: pageController,
  itemCount: urls.length,
  itemBuilder: (context, index) {
    return VideoPlayerWidget(url: urls[index]);
  },
  onPageChanged: (index) {
    if (index + 1 < urls.length) {
      VideoCaching.precache(urls[index + 1], downloadNow: false);
    }
  },
);

5. Revert video uri proxy when proxy server is broken #

Future initPlayControl(Uri uri) async {
  playControl = VideoPlayerController.networkUrl(uri.toLocalUri())..setLooping(true);
  playControl.addListener(playListener);
}

void playListener() {
  if (playControl.value.hasError) {
    print("errorDescription: ${playControl.value.errorDescription}");
    if (playControl.value.errorDescription!.contains("Source error")) {
      initPlayControl(uri);
    }
  }
}
