• I can't install ffmpegs (dependencies) - error with doxygen [mac 10.12.6 Sierra]

  12 septembre 2022, par Lo-Fi Junky

  It installed about 70% of the dependencies it needed to get ffmpegs going, but it got stuck at installing 'doxygen'.

  


  This is the error I got :

• php_ffmpeg some error and solutions

  26 mars 2018, par sonam Sharma

  I have successfully installed php_ffmpeg in my new project with the help of a guy on stackoverflow.com.
  I can do the basic jobs like extracting a frame out of a video
  but when I try to convert the video to another format I get this error :

  Fatal error : Uncaught exception ’Alchemy\BinaryDriver\Exception\ExecutionFailureException’
  with message ’ffprobe failed to execute command "C :\ffmpeg\bin\ffprobe.EXE"

  C :\wamp\www\raidpipe\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFProbe.php on line 244

  I have used this code in my test page :

   <?php
  
   require 'vendor/autoload.php';
  
   $ffmpeg = FFMpeg\FFMpeg::create();
  
   $video = $ffmpeg->open('test/sample3.mp4');
  
   $video
  
  ->filters()
  
  ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
  
  ->synchronize();
  
    $video
  
  ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(19))
  
  ->save('test/clip/frame123.jpg');
  
    $video
  
  ->save(new FFMpeg\Format\Video\X264(), 'export-x264.mp4')
  
  ->save(new FFMpeg\Format\Video\WMV(), 'export-wmv.wmv')
  
  ->save(new FFMpeg\Format\Video\WebM(), 'export-webm.webm');
  
   ?>

  When I run this code it gives me the frame without any error

   require 'vendor/autoload.php';
  
    $ffmpeg = FFMpeg\FFMpeg::create();
  
    $video = $ffmpeg->open('test/sample3.mp4');
  
    $video
  
  ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(19))
  
  ->save('test/clip/frame123.jpg');

  Please suggest me a way to convert the video by using the php_ffmpeg
  i need the video to be converted to some basic formats which can be supported by all the browsers and also please let me know is it a good practice to use exc (execute) in php ??

  I got the above code from this link
