• Live stream failed on Youtube

  20 septembre 2023, par kuldeep chopra

  We are currently running an AWS container that utilizes FFmpeg for live streaming while concurrently saving the stream as an MP4 file. However, we encountered an issue during a recent live stream session that was functioning correctly until approximately 13 minutes in, at which point FFmpeg reported the following error logs :

  


  ffmpeg [flv @ 0x555c4bdfe680] Failed to update header with correct duration.
2023-09-07T23:06:38.490+05:30 [flv @ 0x555c4bdfe680] Failed to update header with correct filesize.
2023-09-07T23:06:38.491+05:30 failed => rtmp://a.rtmp.youtube.com/live2/key......
2023-09-07T23:06:38.491+05:30 ffmpeg [tee @ 0x555c48843700] Slave muxer #1 failed: Broken pipe, continuing with 1/2 slaves.


  


  It's worth noting that we have conducted hundreds of live streams on YouTube without encountering this error before ; this is the first occurrence of such an issue.

  


  We would greatly appreciate it if you could investigate and provide insights into the underlying problem causing these error messages.

  


• How to convert a script from youtube-dl

  16 janvier 2020, par danilshik

  There is a bash/batch file script :

  ffmpeg -i `youtube-dl https://www.twitch.tv/zero` -vf fps=fps=60, scale=1920x1080 -c:v libx264 -b:v 500k -preset superfast -c:a copy -f segment -segment_time 60 test.mp4

  The script is not mine, but it allows you to record video with a constant frame rate of parts. Unfortunately in cmd it does not work for me. Already tried everything, I do not know what the error is.

  I am getting No such file or directory.

  Tried 'youtube-dl https://www.twitch.tv/zero', the same error

  I tried "youtube-dl https://www.twitch.tv/zero", error : youtube-dl https://www.twitch.tv/zero: Invalid argument

  What am I doing wrong ? The author assures that he works on linux

  Update

  I tried ffmpeg -i $ (youtube-dl -f best -g https://www.twitch.tv/zero) .... The same error

  Update 2

  Why the video size exceeds 500 Mb ? What am I doing wrong ?

  
  

  Code

  cls && @echo off & setlocal enableextensions enabledelayedexpansion 
  
  set "_tag_00=https://www.twitch.tv/avagg"
  
  set "_tag_01=--ignore-errors --abort-on-error --ignore-config --flat-playlist --geo-bypass "
  
  set "_tag_02=--restrict-filenames --no-part --no-cache-dir --write-thumbnail --prefer-ffmpeg "
  
  set "_tag_03=--ffmpeg-location .\ --postprocessor-args  -i "%%(title)s.%%(ext)s" -vf fps^=fps^=60^,"
  
  set "_tag_04=scale^=1920x1080 -c:v libx264 -b:v 500k -preset superfast -c:a copy -f segment -segment_time "
  
  set "_tag_05=60 %%^(title^)s.mp4"
  
  
  
  youtube-dl "!_tag_00!" -f "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best" -o "%%^(title^)s.%%^(ext^)s" !_tag_1!!_tag_2!!_tag_3!!_tag_4!!_tag_5!
  
  Pause

• Nodejs youtube-dl ffmpeg audio stream

  19 septembre 2015, par Majster

  I have an issue with streaming video from YouTube. I have a http server which attempts to grab the raw video url, pull out the audio, convert it to mp3 and stream it to clients. The issue is that I’m not getting any audio on my client. Code is below (it’s all work in progress so there’s a lot of hardcoded stuff in there).

  // The obvious stuff
  
  var exec = require('child_process').exec;
  
  var spawn = require('child_process').spawn;
  
  var request = require('request');
  
  var http = require('http');
  
  
  
  //Listen for requests
  
  var server = http.createServer(function(req, response) {
  
     //This command runs youtube-dl and gets the video url
  
     var command = './node_modules/youtube-dl/bin/youtube-dl --simulate --get-url http://www.youtube.com/watch?v=5qF_qbaWt3Q';
  
     var exc = exec(command, function(error, stdout, stderr) {
  
        var downloadUrl = stdout.toString(); //Convert the buffer to string
  
        downloadUrl = downloadUrl.substring(0, downloadUrl.length - 1); //And strip the '\n' sign at the end
  
        console.log("This thing is: '" + downloadUrl + "'");
  
        response.writeHead(200, {
  
           'Content-Type': 'audio/mpeg'
  
        }); //When this is mpeg3 browser will download a blank .mp3 file now it tries to stream it
  
  
  
        //Spawn the ffmpeg child process
  
        var child = spawn('ffmpeg', ['-i', 'pipe:0', '-acodec', 'libmp3lame','-f', 'mp3', '-']);
  
        child.stdout.pipe(response); //Pipe it so it writes to our response
  
  
  
        // fs.createReadStream(filePath).pipe(child.stdin); - this is a testing thing ---> fs is filesystem and filePath is a link to a file - works
  
        request({url: downloadUrl, headers: {'Youtubedl-no-compression': 'True'}}).pipe(child.stdin); //Request the data and pipe it to ffmpeg for processing
  
     });
  
  });

  I can provide any additional info if needed. But the thing works if I try to use a file instead of request call so there is no problem with ffmpeg and other settings. Is it possible that YouTube has a protection against downloading videos this way ? I tried to paste the URL of console.log into my browser and nothing happens - no video. How can I fix this ?
