AudioContext HTML5 Player
15 février 2015, par PlytoSo I’ve been playing with the Web Audio API and have the following issue.
I am making a project in which I call an external library’s API with Ajax and get audio back (arraybuffer).
- I send them the text and get audio back.
- This is not necessarily a GET request (can be POST, etc.)
- If text is too large, I split it into smaller chunks and send multiple requests
So far so good, now comes the issue of how to play the multiple audios that I got back.
Since users do not care that I have split the text and actually have multiple audio tracks, I need somehow to make it look like a single track or as a playlist.
So I have tried to :
- merge arraybuffer (apparently it does not work like that and most likely I need ffmpeg or simiar tools to do the merging, which is hard to do on client-side ? (like there is ffmpeg for browsers, but I don’t know how good is it to burden a client with it). If it’s not so, maybe you can suggest something here)
- load it as a playlist, but so far cannot find a library that accepts multiple audiobuffers/audiocontexts and/or gives a playlist with it back.
The easiest solution that I see so far is to create my own small library that accepts AudioBuffers/arraybuffers and go either with the playlist approach or play the ’chunked’ audios one by one and make scrubber that jumps between audio contexts.
Is there a library/easier approach ?
Will be thankful for any suggestions :]

Flutter chewie video player shows incorrect duration for HLS stream
29 mai 2022, par magackameIm using SRS and ffmpeg to create a HLS video stream

I run SRS using docker command

docker run --rm -it -p 1935:1935 -p 1985:1985 -p 8080:8080 ossrs/srs:4 ./objs/srs -c conf/docker.conf


And then post a stream using ffmpeg command


ffmpeg -re -i video.mp4 -c copy -f flv rtmp://localhost/live/livestream


To playback a video in flutter I use Chewie video player (
chewie: ^1.3.2in pubspec.yaml) and this widget code :

import 'package:video_player/video_player.dart';
import 'package:chewie/chewie.dart';
import 'package:flutter/material.dart';

class RoomView extends StatefulWidget {
 const RoomView({Key? key}) : super(key: key);

 @override
 _RoomViewState createState() => _RoomViewState();
}

class _RoomViewState extends State<roomview> {
 late VideoPlayerController _videoController;
 late ChewieController _controller;

 @override
 void dispose() {
 _controller.dispose();
 _videoController.dispose();

 super.dispose();
 }

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

 _videoController = VideoPlayerController.network('http://localhost/live/livestream.m3u8')
 ..initialize().then((_) {
 setState(() {});
 });

 _controller = ChewieController(videoPlayerController: _videoController);
 }

 @override
 Widget build(BuildContext context) {
 return AspectRatio(
 aspectRatio:
 _controller.aspectRatio == null ? 16 / 9 : _controller.aspectRatio!,
 child: Chewie(controller: _controller));
 }
}
</roomview>

The video plays fine and seeking using the playback bar also works, but the video duration is incorrect. I tried streaming videos with different duration(the two minute and twenty minute ones), tried using mp4 and mkv formats as source and/or streaming using mpegts as output container(instead of flv) but all of them had a duration of either one minute or sometimes 10 seconds and the playbar will overflow when reaching the limit(showing something like 2:11/1:05).

When playing some public HLS streams(https://multiplatform-f.akamaihd.net/i/multi/will/bunny/big_buck_bunny_,640x360_400,640x360_700,640x360_1000,950x540_1500,.f4v.csmil/master.m3u8) the video duration is shown correctly so I guess the problem is either the SRS or the ffmpeg.

The question is what am I doing wrong, what parameters should I use for ffmpeg or SRS, and what are other options that I can use to provide a working HLS stream for the player

How to use youtube-dl to record live stream in parts
23 juillet 2021, par VikralJust wondering if that's possible or not to break an m3u8 live stream recording every hour and restart the recording again.


I don't want to press
Ctrl-Cevery hour to stop the recording and restart it again to get a playable downloaded file. Instead, I want to automate this.

Does anyone know if that is possible ?
