• ffmpeg not converting via PHP script

  16 mars 2014, par user3331834

  Essentially, I have this code :

  if(in_array($ext,$audio)&&($ext!=="flac")){
  
      exec("ffmpeg -i -loglevel 'verbose' ".$fileName.".".$ext." ".$fileName.".flac null >/dev/null 2>/var/www/resources/ffmpegAudio.log &",$ffmpegOutput);
  
      print_r($ffmpegOutput);
  
      $editApproveStatus="Audio entry approved. File converted.";
  
  }

  Ultimately, my goal is to convert files and show a live progress of the conversion (or at least something that updates every few seconds), and running in the background, so that the same page can be used to convert further files.

  Now I'm already stuck, because the conversion just isn't working. I know that the preceding code should be fine, since it makes it all the way to this if statement above, and no errors are being throw up by the PHP. However, my log output shows :

  ffmpeg version 0.8.10-6:0.8.10-0ubuntu0.13.10.1, Copyright (c) 2000-2013 the Libav developers
  
    built on Feb  6 2014 20:59:46 with gcc 4.8.1
  
  *** THIS PROGRAM IS DEPRECATED ***
  
  This program is only provided for compatibility and will be removed in a future release. Please use avconv instead.
  
  -loglevel: No such file or directory

  Which also leads me to another question : If ffmpeg is deprecated, and avconv is the way to do, can I still use the exec code in my PHP as is (replacing the ffmpeg bit with avconv) ? From what I've seen so far on the avconv page, it looks similar, but I can't be certain that it's exactly the same.

  So my two questions : Why isn't the file being converted, and is there any change in the syntax between avconv and ffmpeg ?

• Why does PowerShell closes ff-prompt.bat before executing my commands

  9 mars 2014, par sebastian

  Okay guys looks like I have another question to ask, which is kind of related to my last question, which can be found on here : How to start ffprobe with Windows PowerShell. There I was asking how to start ffprobe with Windows PowerShell and after trying out a few things I got it, well lets say, started for a second before it closes again.
  I tried it with following commands in PowerShell :

  $env:Path = ';C:\Users\Administrator\bin\'
  
  $title = "A_Day_for_Cake_and_Accidents"
  
  Start-Process ff-prompt.bat -ArgumentList "ffprobe -show_streams -select_streams v -print_format xml -count_frames C:\Users\Administrator\Desktop\dcp_bearbeitet\$title\$title.mov > C:\Users\Administrator\Desktop\dcp_bearbeitet\$title\totalframes.xml"

  The result, and that is the strange thing, is the xml file with only the standard text from the ff-prompt.bat, which looks like this :

  C :\Users\Administrator>ECHO OFF

  Current directory is now : "C :\Users\Administrator\bin"
  The bin directory has been added to PATH

  My first thought was, that it did not work at all, but then I was wondering why I get an XML file when it is not working at all. PowerShell executes the ff-prompt.bat for maybe a second, before PowerShell shuts down the ff-prompt.bat again without doing half of my commands. Does anybody know why ff-prompt gets closed before executing all of my commands ?

  EDIT : So what I tried is something that should execute it directly, but in fact I get a shitload of errors :

  $title = "A_Day_for_Cake_and_Accidents"
  
  $Cmd = ‘C:\Users\Administrator\ffmpeg\bin\ffprobe.exe’
  
  $Arg1 = ’ffprobe '
  
  $Arg2 = ‘-show_streams ’
  
  $Arg3 = ‘-select_streams v '
  
  $Arg4 = ‘-print_format xml '
  
  $Arg5 = ‘-count_frames '
  
  $Arg6 = "C:\Users\Administrator\Desktop\dcp_bearbeitet\$title\$title.mov >"
  
  $Arg7 = " C:\Users\Administrator\Desktop\dcp_bearbeitet\$title\totalframes.xml"
  
  & $Cmd $Arg1 $Arg2 $Arg3 $Arg4 $Arg5 $Arg6 $Arg7

  Error message(s) I get :

  "ffprobe.exe
  Failed to set value '-select_streams v ' for option 'show_streams ' : Option not found"

  The problem I am facing now is that -show_streams does not get a value, so maybe that is the reason why he uses the next parameter as a value, is there anything I can do ?

• ffmpeg not work with PHP exec()

  14 mars 2014, par user27133

  I need to convert video and create image using ffmpeg. I downloaded this package from zeranoe for windows 8 64x and put in c:/ffmpeg folder.

  I check for ffmpeg installed in windows using cmd : ffmpeg -version

  Now I test convert video using php :

  $raw_video_path = 'C:\xampp\htdocs\video\ff\examples\5.flv';
  
  $new_flv = DIRNAME(DIRNAME(__FILE__)).'/ff/examples/video/2654.flv';
  
  $new_png = DIRNAME(DIRNAME(__FILE__)).'/ff/examples/video/2647-resampled.jpg';
  
  
  
  @exec("ffmpeg -i ".$raw_video_path."  -ab 56 -ar 44100 -b 200 -r 15 -s 320x240 -f flv ".$new_flv."");
  
  @exec("ffmpeg  -itsoffset -4  -i ".$new_flv." -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 ".$new_png." ");

  Now, This not work for me !! How do I can fix this ?

  For ffmpeg, I need to install/active php ffmpeg extension ?
