Split audio in segments on silence with ffmpeg
28 mars 2020, par MaralI’m trying to automatically split audio files in 5min segments without splitting words and by splitting on silent parts.
Do you know any ways to do this ?Is there a way I can combine these 2 scripts and also make the duration of the splits less than (around) 5 mins ?
ffmpeg -i filename -af silencedetect=noise=-30dB:d=0.5 -f null - 2and
ffmpeg -i test.mp3 -ss 00:00:20 -to 00:00:40 -c copy -y temp.mp3I tried using these in my Go code like this, but it looks like it isn’t the right way.
package main
import (
"fmt"
"os/exec"
"os"
"io/ioutil"
"log"
)
func main() {
filename := "test.wav"
args := []string{"-i", filename, "-af", "silentdetect=noise=-30dB:d=0.5","-f", "null", "-","2>", "output.txt"}
cmd := exec.Command("ffmpeg", args...)
errcmd := cmd.Run()
if errcmd != nil {
fmt.Println(errcmd)
fmt.Println("problem detecting silence")
} else {
fmt.Println("silence detected")
}
file, err := os.Open("output.txt")
if err != nil {
fmt.Println(err)
}
body, readErr := ioutil.ReadAll(file)
if readErr != nil {
log.Fatal(readErr)
}
//somehow read silent start time and end time from the file and split

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).
