How to sync network audio with a different network video and play it with chewie
26 mars 2023, par Rudra SharmaI am trying to stream a reddit videos on my app. For that reason I am using Reddit API but it is only giving the video url like 'redd.it/mpym0z9q8opa1/DASH_1080.mp4 ?source=fallback' with no audio but after some research I found out that we can get audio url by editing video url 'redd.it/mpym0z9q8opa1/DASH_audio.mp4 ?source=fallback'.


Now I have both audio and video url with me how can I sync them on network and stream them on my app using chewie package (video player).


This my code so far


import 'dart:async';
import 'dart:convert';
import 'package:http/http.dart' as http;
import 'package:flutter/material.dart';
import 'package:video_player/video_player.dart';
import 'package:chewie/chewie.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
 @override
 Widget build(BuildContext context) {
 return MaterialApp(
 title: 'Reddit Videos',
 theme: ThemeData(
 primarySwatch: Colors.blue,
 visualDensity: VisualDensity.adaptivePlatformDensity,
 ),
 home: VideoPlayerScreen(),
 );
 }
}

class VideoPlayerScreen extends StatefulWidget {
 @override
 _VideoPlayerScreenState createState() => _VideoPlayerScreenState();
}

class _VideoPlayerScreenState extends State<videoplayerscreen> {
 final List<string> _videoUrls = [];

 @override
 void initState() {
 super.initState();
 _loadVideos();
 }

 Future<void> _loadVideos() async {
 try {
 final videoUrls =
 await RedditApi.getVideoUrlsFromSubreddit('aww');

 setState(() {
 _videoUrls.addAll(videoUrls);
 });
 } catch (e) {
 print(e);
 }
 }

 @override
 Widget build(BuildContext context) {
 return Scaffold(
 appBar: AppBar(
 title: Text('Reddit Videos'),
 ),
 body: SafeArea(
 child: _videoUrls.isNotEmpty
 ? _buildVideosList()
 : Center(child: CircularProgressIndicator()),
 ),
 );
 }

 Widget _buildVideosList() {
 return ListView.builder(
 itemCount: _videoUrls.length,
 itemBuilder: (context, index) {
 return Padding(
 padding: const EdgeInsets.all(8.0),
 child: Chewie(
 controller: ChewieController(
 videoPlayerController: VideoPlayerController.network(
 _videoUrls[index],
 ),
 aspectRatio: 9 / 16,
 autoPlay: true,
 looping: true,
 autoInitialize: true,
 ),
 ),
 );
 },
 );
 }
}

class RedditApi {
 static const String BASE_URL = 'https://www.reddit.com';
 static const String CLIENT_ID = 'id';
 static const String CLIENT_SECRET = 'secret';

 static Future> getVideoUrlsFromSubreddit(
 String subredditName) async {
 final response = await http.get(
 Uri.parse('$BASE_URL/r/$subredditName/top.json?limit=10'),
 headers: {'Authorization': 'Client-ID $CLIENT_ID'});

 if (response.statusCode == 200) {
 final jsonData = jsonDecode(response.body);
 final postsData = jsonData['data']['children'];

 final videoUrls = <string>[];

 for (var postData in postsData) {
 if (postData['data']['is_video']) {
 videoUrls.add(postData['data']['media']['reddit_video']
 ['fallback_url']);
 }
 }

 return videoUrls;
 } else {
 throw Exception("Failed to load videos from subreddit");
 }
 }
}
</string></void></string></videoplayerscreen>

I think the code is self explainatory about what I am trying to achieve (Trying to make a client for reddit).
