• PHP-FFMpeg Installation and Basic Usage on windows issue

  7 mai 2017, par Miky

  following the README I installed PHP FFmpeg through Composer and I downloaded binaries from https://ffmpeg.zeranoe.com/builds/
  now I’m trying to run the "Basic Usage" example :
  

  <?php
  
  require("vendor/autoload.php");
  
  $ffmpeg = FFMpeg\FFMpeg::create();
  
  $video = $ffmpeg->open('video.mpg');
  
  $video
  
      ->filters()
  
      ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
  
      ->synchronize();
  
  $video
  
      ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(10))
  
      ->save('frame.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');
  
  ?>

  but i receive "Executable not found" errors because I didn’t understand where to put them
  

  I also tried specifying binaries ffmpeg.exe and ffprobe.exe with :
  

  $ffmpeg = FFMpeg\FFMpeg::create(array(
  
      'ffmpeg.binaries'  => '/pathtobin/ffmpeg',
  
      'ffprobe.binaries' => '/pathtobin/ffprobe',
  
      'timeout'          => 3600, // The timeout for the underlying process
  
      'ffmpeg.threads'   => 12   // The number of threads that FFMpeg should use
  
  ), $logger);

  but still same error... am I making a mountain out of a molehill ? any help is appreciated... Thanks

  EDIT 1

  I added ffmpeg\bin folder to system path and I can run executables from cmd from anywhere, but now I’m getting this error : "Executable not found, proposed : avprobe, ffprobe"...
  instead, if I give binary paths explicitly, I get 'ffprobe failed to execute command "C:/FFmpeg/bin/ffprobe.exe" "-help" "-loglevel" "quiet"'

  what am I doing wrong ?

  EDIT 2

      'ffmpeg.binaries'  => 'C:/inetpub/wwwroot/FFmpeg/ffmpeg.exe',
  
      'ffprobe.binaries' => 'C:/inetpub/wwwroot/FFmpeg/ffprobe.exe',
  
      'timeout'          => 3600, // The timeout for the underlying process
  
      'ffmpeg.threads'   => 12,   // The number of threads that FFMpeg should use
  
  ));
  
  $video = $ffmpeg->open('input.mp4');
  
  ?>

  result

• How do I make a C# win form program that breaks a video down to frames, then put those frames back together to make a video ?

  30 juillet 2015, par Atom Scott

  First, I’m fairly new to C sharp so I’m looking for a thorough and easy to understand answer.

  How do I make a C# win form program that breaks a video down to frames, then puts those frames back together to make a video ?
  I also want to be able to select which frames to extract by setting an interval time. For example, extract frames that are one second apart.
  Is this possible, I have done some research but I don’t understand how to use the codes displayed on the following websites.

  Supposedly code to breakdown video into frames. However I do not know where to put it. Do I make it the event for a button or something. From my own research I am guessing this uses ffmpeg. But I’m not exactly sure how to use ffmpeg, I have tried downloading Aforge, and use Aforge.Video.ffmpeg. But I’m stuck there.
  http://www.researchgate.net/post/Has_anyone_code_in_C_to_read_video_file_and_split_it_into_frames[^]

  Code for making a video from images, it looked promising so i tried to copy and paste it visual studio. However the line using BytescoutImageToVideoLib ; has an error asking me whether I am missing a reference. What reference am I missing ?
  http://bytescout.com/products/developer/imagetovideosdk/imagetovideosdk_first_step_with_visual_c_sharp_net.html[^]

  I also noticed that there was a page on code project for something similar to this, but the downloadable demo project didn’t work at all. I didnt see the point in spending time on something where the end product is broken.

  Any help is greatly appreciated.
