• ffmpeg - How to determine if -movflags faststart is enabled ? PHP

  6 juillet 2017, par IIIOXIII

  While I am able to encode an mp4 file which I can play on my local windows machine, I am having trouble encoding files to mp4 which are readable when streaming by safari, etc.

  After a bit of reading, I believe my issue is that I must move the metadata from the end of the file to the beginning in order for the converted mp4 files to be streamable.

  To that end, I am trying to find out if the build of ffmpeg that I am currently using is able to use the -movflags faststart option through php - as my current outputted mp4 files are not working when streamed online.

  This is the way I am now echoing the -help, -formats, -codecs, but I am not seeing anything about -movflags faststart in any of the lists :

  exec($ffmpegPath." -help", $codecArr);
  
  for($ii=0;$iibr>';
  
  }

  Is there a similar method of determining if -movflags fastart is available to my ffmpeg build ? Any other way ? Should it be listed with any of the previously suggested commands ? -help/-formats ?

  Can someone that knows it is enabled in their version of ffmpeg check to see if it is listed under -help or -formats, etc.?

  TIA.

• Replicate the format of a video to another

  10 octobre 2017, par Basj

  Let’s say I have :

  • video1.avi which is perfectly played (both sound and image) on my TV’s USB media input

  • video2.avi which is not recognized by the TV : "Imposible to read this format"

  I have tried lots of solutions, like :

  ffmpeg -i video2.avi -codec:a libmp3lame -q:a 0 -ac 2 -ar 48000 -joint_stereo 0^
  
         -codec:v libxvid -q:v 25 video2_reencoded.avi

  and when I compare video1.avi with video2_reencoded.avi with MediaInfo, they look similar in most aspects, but finally the TV won’t play video2_reencoded.avi.

  Is there a way with ffmpeg, to replicate all the specifications of video1.avi (sound encoding properties, video encoding properties, image size, container type, etc.) on video2.avi ?

  ---

  Appendix : output of MediaInfo for the three videos. In this specific example, video2.avi and video2_reencoded.avi are half-working : image ok but not the sound. In other video examples I tried, video2.avi and video2_reencoded.avi would be both totally "Impossible to read".

• AFTER PHP-FFMpeg not converting (error with ffmpeg)

  15 juin 2018, par Magurean Dan Sergiu

  I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

  Use -h to get full help or, even better, run 'man ffmpeg'

  But when I try to convert a video file with a php script it throws me a very long error.
  PHP Code :

  $video
  
         ->filters()
  
         ->synchronize();
  
  $format = new FFMpeg\Format\Video\X264();
  
  $format->on('progress', function ($video, $format, $percentage) {
  
      echo "$percentage % transcoded";});
  
  $video
  
        ->save($format,$_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.mp4');
  
  ?>

  Error displayed :

  Unknown encoder 'libx264'

  My question is what to do next ? I have wasted 3 days to make this work and this is the furthest I have come. How can I test if libx264 is installed corectly ? And if it is not installed corectly how cand I reinstal or make it work ?

  After a few modifications

  I have used an already installed ffmpeg, and removed a few commands (that were by default the same) and this time I used only the command line.
