• How to install ffmpeg for generating thumbnail images ? I got no package ffmpeg available while run on Linux(centos) terminal

  How to install ffmpeg for generating thumbnail images ? I got "no package ffmpeg available" while run on Linux(centos) terminal by using "yum ffmpeg install" command.

  I need to install ffmpeg for generating thumbnail images, it’s working fine in localhost(Windows), but doesn’t work in Linux (I don’t know server platform). I have refer some website. In that they put like exe are not execute in linux server, we need to install ffmpeg programmatically. Can anyone give me suggestion. I have refer some website, but that wasn’t useful.

  My code :

  $video = "../../".$down_path;
  
      $rand=mt_rand(111111,999999);
  
      //where to save the image
  
      $image1 = "../../completed_project/thumb/".$rand.'ss.jpg';
  
      $image2 = "../../completed_project/thumb/".$rand.'uu.jpg';
  
      $image3 = "../../completed_project/thumb/".$rand.'rr.jpg';
  
  
  
      $thumb_image1 = "completed_project/thumb/".$rand.'ss.jpg';
  
      $thumb_image2 = "completed_project/thumb/".$rand.'uu.jpg';
  
      $thumb_image3 = "completed_project/thumb/".$rand.'rr.jpg';
  
  
  
      //time to take screenshot at
  
      $interval1 = 2;
  
      $interval2 = 4;
  
      $interval3 = 5;
  
      //screenshot size
  
      $size = '320x240';
  
  
  
      //ffmpeg command
  
      $cmd1 = "$ffmpeg -i $video -deinterlace -an -ss $interval1 -f mjpeg -t 1 -r 1 -y -s $size $image1 2>&1"; 
  
      $cmd2 = "$ffmpeg -i $video -deinterlace -an -ss $interval2 -f mjpeg -t 1 -r 1 -y -s $size $image2 2>&1";  
  
      $cmd3 = "$ffmpeg -i $video -deinterlace -an -ss $interval3 -f mjpeg -t 1 -r 1 -y -s $size $image3 2>&1";  
  
      $return = `$cmd1`.`$cmd2`.`$cmd3`;
  
      print_r($cmd1);

  I’ve got this output :

  ffmpeg.exe -i ../../completed_project/606560114793SK_PROMO-45s.mp4 -deinterlace -an -ss 2 -f mjpeg -t 1 -r 1 -y -s 320x240 ../../completed_project/thumb/362796ss.jpg 2>&1

  As the title says : weird problem. I've been struggling to make this work for a whole day but to no avail. Any help would be deeply appreciated.

  I expect the subprocess.run() would produce the same result. I've tried all versions of paths (different kind of escaping) but none of the aforementioned one worked.

  25 juin 2023, par Yogi Arif Widodo

  my component / recording is using blachole plugin on macOS.

  


  engine : 13" Macbook Pro M1 ( macOS 13.2 / Ventura )

  


  step to reproduce

  


  

  1. my output is screenRecordingAudio ( this name is custom name ).

  


  


  // screenRecordingAudio in audioMidi : 
BlackHole 16ch [mark as checked on use]
External Headphones [mark as checked on use]


  


  


  screenRecordingAudio is using on by click on right top of bar UI, click sound, click screenRecordingAudio.

  


  


  OR

  


  


  screenRecordingAudio is using on Settings ➡️ Sounds ➡️ Output ➡️ then choose screenRecordingAudio

  


  


  

  2. my input is quickTimeInput ( this name is custom name ).

  


  


  // quickTimeInput in audioMidi : 
BlackHole 16ch [mark as checked on use]


  


  

  3. then using ⌘ + shift + 5 , on option i use quickTimeInput

  


  4. i use these command to convert into mp4 and also purpose to get more small size video

  


  


  #!/bin/bash

# greet the user
function yoVideo() {
  ffmpeg -i $1.mov -c:v libx264 -preset medium -crf 23 -c:a aac -b:a 128k -movflags +faststart $1.mp4
}


  


  OR

  


  ffmpeg -i yogiarifwidodo.mov -c:v libx264 -preset medium -crf 23 -c:a aac -b:a 128k -movflags +faststart yogiarifwidodo.mp4


  


  

  5. then i move the video into my phone android.

  


  6. then when i tried to upload on youtube as short, its cannot be process to upload ( its just do nothing ) but when i upload on facebook reels its work also on instagram story its still working also for whatsapp story.

  


  


  when i didnt convert into mp4 its also happend and in any other case for example whatsapp story , its lagging to review video before upload . its happend to on instagram .
but when i force upload , the result video is good and smooth . then i re download my video its still best video and when try to upload my download video , there is no lagging in any condition.

  


  how to get ffmpeg perform into mp4 and also no lagging on editing while uploading at whatsapp story or instagram story or facebook , etc ?
by the way i dont know command ffmpeg , the code is copied from stackoverflow and i forgot where is it.
