• Kurento with RTMP is not working on AWS EC2

  4 mars 2019, par akash

  We have used kurento media server for live streaming and modified the existing code to stream the same on Facebook and YouTube using FFMPEG.

  Application is working fine at our local machine and also we have tested with docker container on our staging environment and it is working successfully on that but not working on the EC2 machine.

  Although Live streaming working fine on AWS EC2 when we have not intergrated feature to stream on Facebook and YouTube.

  Just to clear we are not able to live stream on Facebook and Youtube on EC2 instance but it is working on local.
  Please suggest !!

  Thanks in advance.

• PHP upload video files to database

  13 janvier 2016, par Mick Jack

  I am working on a school project that let users upload video files to a server. Server will compress the video using ffmpeg and store the file in upload folder. Other users will be able to stream the uploaded videos.

  My question is how do i retrieve the video that ffmpeg generated and store the link in the database ?

  i am using this code but it only retrieve path of the original video.

  $filePath = dirname(__FILE__); 

  partial code of Upload.php

  $target_dir = "upload/"; //where you want to upload the files to
  
  $target_file = $target_dir.basename($_FILES['file']['name']);
  
  $fileType = pathinfo($target_file, PATHINFO_EXTENSION);
  
  $newFileName = $target_dir.sha1(pathinfo(basename($_FILES['file']['name']), PATHINFO_FILENAME)).'-'.time().'.'.$fileType;
  
  move_uploaded_file($_FILES['file']['tmp_name'], $newFileName);
  
  $unique_id = rand(1000000,9999999);
  
  
  
  shell_exec("C:\\ffmpeg\\bin\\ffmpeg.exe -i ".$newFileName." -vcodec libx264 -crf 20 \"upload\\{$newFileName}\" > logfile.txt 2>&1");
  
  
  
  /// save information into database
  
                  $username = "root";
  
                  $password = "";
  
                  $hostname = "localhost"; 
  
                  $dbname = "test_database";
  
  
  
                  //connect to the database
  
                  $dbc = mysqli_connect($hostname, $username, $password, $dbname) or die ("could not connect to the database");
  
  
  
                  //execute the SQL query and return records
  
                   $result = mysqli_query($dbc, "INSERT INTO `viewvideo` (`vID`, 'video_id`, `video_link`) VALUES ('', '".$unique_id."', '".$newFileName."')");
  
  
  
                  if(!$result){echo mysqli_error($dbc); }
  
  
  
                  echo $result;
  
  
  
              /*  
  
                  declare in the order variable
  
                  $result = mysqli_query($dbc, $sql); //order executes
  
                  if($result){
  
                      echo("<br />Input data is succeed");
  
                  } else{
  
                      echo("<br />Input data is fail");
  
                  }
  
              */  
  
  
  
                  //close the connection
  
                  mysqli_close($dbc);

• How to create a clip from an mp4-file quickly ?

  26 mars 2023, par Moritz Groß

  I have a web app that lets users download a clip from a mp4-file specified before. Currently I use ffmpeg via python like this :

  


  os.system('ffmpeg -i original_video -ss {start} -t {duration} result_video')


  


  Processing 10 minutes of 720p video with this method also takes a few minutes (during the execution, ffmpeg displays speed=3x on average). Does this mean processing 10 minutes of video takes 3minutes & 20 seconds as I understand it ?

  


  Is this slow of a performance expected ? Can I improve it by using an other filetype than mp4 ?
