const fourth = './videos/fourth.mp4'

ffmpeg.setFfprobePath(ffprobe.path)

app.use(express.json())

app.use("/",(req,res)=>{
 res.send("hello")

 ffmpeg()
 .input(first)
 .input(second)
 
 .on('end', function() {
 console.log('files have been merged succesfully');
 })
 .on('error', function(err) {
 console.log('an error happened: ' + err.message);

ffmpeg video download shows errors in log
15 juin 2022, par PeterMi'm trying to download media (video) files from sharepoint (i have view access), but during the process i get several "Connection to tcp ://xxx.xxxxx.ms:443 failed : Error number -138 occurred" or "HTTP error 503 Service Unavailable" errors (see following screenshots : tcp error HTTP error 503 )


i get more errors with the following parameters :


ffmpeg -i "https://theURLtoTheManifestYouCopiedHere" -codec copy downloadedVideo.mp4


less errors with :


ffmpeg -re -vsync 1 -i "https://theURLtoTheManifestYouCopiedHere" -codec copy downloadedVideo.mp4


the options suggested in this article didn't help : https://medium.com/intrasonics/robust-continuous-audio-recording-c1948895bb49


the output video is ok, but sound seems to be missing occasionally (a few seconds worth)


ffmpeg version used is 2022-06-12-git-4d45f5acbd-essentials_build-www.gyan.dev (executable for windows)


any advice ?

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
