• 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 ?

  ));
  
  $video = $ffmpeg->open('input.mp4');
  
  ?>

  result

• Matplotlib can not save animation

  1er avril 2020, par Justin Furuness

  I have a matplotlib animation and it will not save. If I do not save it, it runs totally fine and without error. When I try to save it errors with a message that is not helpful. I have googled this error and checked everything, but I cannot seem to find an answer to this problem. I have installed ffmpeg. Am I doing something wrong that is obvious ? I am running on ubuntu 19.10 with matplotlib 3.2.1 if that matters.

  



  The code to save the animation is below :

  



      def run_animation(self, total_rounds):
        anim = animation.FuncAnimation(self.fig, self.animate,
                                       init_func=self.init,
                                       frames=total_rounds * 100,
                                       interval=40,
                                       blit=True)
#        Writer = animation.writers['ffmpeg']
#        writer = Writer(fps=15, metadata=dict(artist='Me'), bitrate=1800)
        anim.save('animation.mp4')


  



  The error traceback :

  



  2020-04-01 02:20:58,279-INFO: MovieWriter._run: running command: ffmpeg -f rawvideo -vcodec rawvideo -s 1200x500 -pix_fmt rgba -r 25.0 -loglevel error -i pipe: -vcodec h264 -pix_fmt yuv420p -y animation.mp4

  Thanks a million for your help

  


• Continously read file in Ruby and save into pipe

  7 juillet 2016, par stiller_leser

  I am trying to continously read a file and save the output into a IO.pipe. The motivation being that ffmpeg which has been spawned before and given the r-end of the pipe as STDIN will then convert the video.
  This is what I have so far :

      r,w = IO.pipe
  
      ffmpeg_args = ' -i pipe:0 "test.mp4"'
  
      pid = Process.spawn('ffmpeg'+ffmpeg_args, {STDIN => r, STDERR => STDOUT})
  
      Process.detach pid
  
      File.open(@options['filename'], 'rb') do |file|
  
        while line = file.gets
  
          w.write line.read
  
        end
  
      end

  I had success with declaring the input file directly as STDIN for the process, but this lead to an early termination of ffmpeg since it had reached the end of the file. With the code above ffmpeg complains about invalid data.

  Is there any way this could be achieved ?
