• ffmpeg : change command line option -dump to work without -loglevel debug

  10 décembre 2015, par Tom Marecek

  ffmpeg : change command line option -dump to work without -loglevel debug
   hex and -dump command line options do nothing unless -loglevel debug is set.
   dump by itself is useful for monitoring live streams (to get the current PTS for example)  however when it is used with -loglevel debug for an RTMP stream, librtmp also dumps the packet data which makes the output too noisy.
  do_pkt_dump is only set in check_keyboard_interaction or by the -dump command line option so this change should have no effect on any other parts of the code..

• FFMPEG-PHP converted videos don't work on mobiles

  16 avril 2018, par casusbelli

  I’m working on a upload script where users can upload videos however I’m having an issue with FFMPEG-PHP : The converted videos don’t work on mobiles while they are working fine on desktop.

  //FFMPEG Instance
  
  require_once '/root/vendor/autoload.php';
  
  $ffmpeg = FFMpeg\FFMpeg::create();
  
  $video = $ffmpeg->open($temp_path);
  
  
  
  //WEBM Convert
  
  $format_webm = new FFMpeg\Format\Video\WebM();
  
  $video->save($format_webm, 'video.webm');
  
  
  
  //MP4 Convert
  
  $format_mp4 = new FFMpeg\Format\Video\X264();
  
  $format_mp4->setAudioCodec("libmp3lame");
  
  $video->save($format_mp4, 'video.mp4');

  Fatal error : Uncaught

  Any help ?

• PHP/ffmpeg (Windows 7) : - Permission Denied. Tried everything, but still doesn't work

  14 janvier, par user365465

  I have a command-line PHP script that, when given the folder name as an argument when executing the script, will find all images in said folder and resize them using FFmpeg. Problem is, I always get a Permission Denied error in FFmpeg when it attempts to get at the files within the folder. This is while being on Windows 7.

  



  The big problem is that I've tried every solution that keeps popping up on the interwebs when I search for how to fix it. I've changed the settings in Avast !, did the attrib command (both as normal and "Run as Administrator") to unmark as read-only, took ownership of the folder both via command line and using that GUI takeown context menu thing everyone keeps throwing around (obviously before my efforts to mark everything as not-read-only), messed with permissions, everything. I keep searching and searching for a solution, but all of the sites keep throwing out the same things over and over again - things that I've already tried multiple times. I'm at the end of my rope here. All I want to do is resize images quickly and automatically so I can put them up on my website, yet this has been a massive headache...

  



  Please help me ! :(

  



  Update (Additional Points) :

  



  


  • The error is through FFmpeg, not PHP. FFmpeg spits out the permission denied error, the script just continues doing what it does normally (or, at least, it would if it weren't for my die statement that kicks in in the event of FFmpeg failing).

  


  • FFmpeg will execute just fine if it's run normally through the command line instead of through the script. However, this does not help the problem of me having to resize hundreds of photos by hand !

  


  • I'm just running this script in the normal terminal using the CLI engine. Weird use for PHP, I know, but since I already knew how to work with FFmpeg in PHP (but in Linux !) so I figured I might as well use the code as a normal, stand-alone program...

  


  • FFmpeg spits out the same error regardless of which PHP function is used to execute it. It happens for shell_exec, exec, passthru, and system.
