• FFMPEG Stdout Line

  23 janvier 2023, par ai manifest

  I'm just wondering why Google Colab doesn't show FFMPEG's STDOUT line, showing the frame progress, fps, duration, time elapsed, etc. Jupyter notebooks and jupyter lab shows it, so I'm not sure why colab doens't. Thanks in advance.

  


  When running the ffmpeg command, (!ffmpeg -i input.mp4 output.mp4), there is no stdout line in google colab, but if run in jupyter notebooks, the stdout lines show. Just curious why this is.

  


• Add diffrent animation for diffrent frame in video using ffmpeg android

  13 juin 2016, par Sachin Suthar

  I am trying to apply animations for the particular video frame but hereby I’m not seeing that video frame by which I have to apply the animation. I only need fade in and fade out frame and display it as slide show video. Do you have any idea about this ?

  I am using the same command which was given to this url but for the particular 5 second video hide and not getting slide show effect.

• what is ffmpeg exit code 2 ? and also output error array is empty and not working in php

  14 juin 2019, par Mehdi Zamani

  I use ffmpeg to convert bitrate to 128 but not working in php

   exec("ffmpeg -i input.mp3 -codec:a libmp3lame -b:a 128k output().mp3 2>&1", 
  
   $output, $exit_code);
  
   if ($exit_code!= 0) {
  
      $data['message'][] = "Error";
  
   }
  
  
  
   print_r($output);
  
   print_r($exit_code);
  
   exit;

  After running this code show error code 2.
  The output is an empty array and also exit_code is 2 and not create output.mp3 file.

  I already study How can I find out what this ffmpeg error code means ? but this isn’t my problem and don’t explain error code 2 or error code 2 is not defined. My problem is dont show any error and error message is empty just exit_code show 2 that means is some error happened.
