  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.

by the way i dont know command ffmpeg , the code is copied from stackoverflow and i forgot where is it.

  


• Running command Subprocess python failed but the same exact command runs well in Terminal

  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've tried every one of the below path but still errors: Fontconfig error: Cannot load default config file: No such file: (null)

            ]
print(' '.join(comd))
subprocess.run(comd, check=True, capture_output=True, text=True) # Failed


# The below command runs successfully in the terminal.
# ffmpeg -f lavfi -i color=c=black:s=1280x720:d=2.352000 -vf drawtext=fontfile="C\\://Users/acer/AppData/Local/Microsoft/Windows/Fonts/jf-openhuninn-1.1.ttf":text='abc':fontcolor=white:fontsize=24:x=(w-text_w)/2:y=(h-text_h)/2 -c:v libx264 -t 2.352000 -pix_fmt yuv420p output_Test-0004.mp3.mp4



  


  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.

  


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

  16 mai 2015, par Intrepid Uliyar

  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
