• RTSP to RTMP using FFMPEG on Raspberry Pi to YouTube Livestream ends prematurely (and sometimes doesn't start)

  12 mars 2021, par user203875

  I have been running a program from my raspberry pi 4 that converts a RTSP network camera feed to RTMP for YouTube. The stream used to run non-stop every day. I didn't have to do anything. I have a program in place that would restart if the feed died.

  


  Nothing has changed with that program in 2 years. About a month ago, the feed stopped working. I just started into trying to figure out why. Maybe someone has some ideas on what is going on ?

  


  In order for me to start the feed, I must also start a studio.youtube.com browser session showing the feed information. If that web page is up and running, the live stream will start. While I can't say for certain that it NEVER starts without this session running, it seems that way.

  


  Usually the stream lasts for an hour or two. Rarely more than four hours.

  


  When I start up a studio.youtube.com session after the stream dies the "Dimiss" or "Edit in Studio" message is on the page. I have to hit "dismiss" before I can start up the stream again.

  


  Is there a solution to this ?

  


  Again, my program didn't change, so I'm at a loss for what I can do to fix this.

  


• How can we reduce the size of audio file after uploading ?

  8 novembre 2019, par Arjun Pujari

  I have used this command in the terminal to install the package : composer require pbmedia/laravel-ffmpeg. The package is successfully downloaded, but I don’t know how to use it. I don’t even know if this package can also reduce the audio file size or not.

  Anyone know any other library or package ?

      
  
          <form action="{{route('upload')}}" method="post" enctype="multipart/form-data">
  
              Select Audio to upload:
  
              <input type="file" />
  
              <input type="submit" value="upload MP3" />
  
          </form>
  
      
  
  
  
  
  
  &lt;?php

  Here is my controller. Write basic code for save file :

  namespace App\Http\Controllers;
  
  
  
  use Illuminate\Http\Request;
  
  use Pbmedia\LaravelFFMpeg\FFMpeg;
  
  
  
  class FileCompress extends Controller
  
  {   
  
      public function compressFile(Request $request)
  
      {
  
            $uploadFileName = mt_rand().time(). '.' . $file->getClientOriginalExtension();
  
            $filetype = substr($file->getClientMimeType(), 0, strpos($file->getClientMimeType(), "/"));
  
  
  
          if($filetype == 'video'){
  
  
  
            $localpath =  public_path().'/videos/'.$uploadFileName;
  
           //code for video file compress.
  
          }else{
  
            //code for audio file compress.
  
          }
  
      }
  
  }

  But I need to reduce the audio file size when a file is uploaded or reduce the file size immediately after the file upload. How can i do that ?
