• Prevent output in error log when ffmpeg job is initiated via PHP's shell_exec()

  19 janvier 2016, par Jake

  I’m getting the entire output of the ffmpeg command printed to my server’s error.log — but as far as I can tell, the jobs complete successfully with no error.

  Is there any way to suppress the output ? I have seen people append stuff like >/dev/null 2>/dev/null & to their command, however that forces the command to return immediately and the job runs in the background. Unfortunately, I need the job to run in the foreground, because I need to do stuff with the output once the job is done.

  Here’s the command I am running...

  shell_exec('ffmpeg -i input.mp4 -f mp4 -c:v libx264 -preset slow -crf 24 -s 1280x720 -c:a libfdk_aac -profile:a aac_he -ar 22050 -b:a 64k -movflags +faststart output-1280x720.mp4');

  Here’s the output I am seeing...

• FFmpeg : convert .mpg video to .mp4 without losing quality

  20 novembre 2024, par reterius

  How can I convert a .mpg video to .mp4 without losing quality ? My attempts below :

  


  $INCPATH = dirname(__FILE__).'/';

$id = 99999;
$ext = "MPG";

$input_dir = $INCPATH."../img/videos/".$id.".".$ext ;
$output_dir2 = $INCPATH."../img/videos/".$id.".mp4" ;

$q = '/usr/bin/ffmpeg -i '.$input_dir.' -c:v libx264 -c:a libfaac -r     30 '.$output_dir2." 2>&1" ;

$out = shell_exec($q) ;
$input_dir  = $output_dir2 ;

echo var_dump($out);


  


  Output of running that script :

• FFMPEG 'Fontconfig error : Cannot load default config file' error Windows

  30 décembre 2024, par Merel

  I am trying to make a short video in FFMPEG, where a word stays on screen for the duration of the video (0.5s). My FFMPEG code looks like this :

  



  ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf "drawtext=fontfile= ‘c\:\Windows\fonts\calibri.ttf':fontsize=18:  fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text='word'" output.mp4

  



  However, I keep getting the following error (see below for full output) :

  



  Fontconfig error: Cannot load default config file 
[Parsed_drawtext_0 @ 000001c2918cef00] Using "C:/Windows/fonts/mingliub.ttc"


  



  I figured it had something to do with the path to the font file. I also tried copying the font file to my FFMPEG map and map the font path to the FFMPEG directory :

  



  ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf
"drawtext=fontfile=‘C:\FFMPEG\bin\calibri.ttf':fontsize=18: 
fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text='word'" output.mp4'


  



  This doesn't work either. I do get an output video.mp4 video, but the font is wrong. Here is the full output I get. It is the same for both code examples above :

  



   c:\FFMPEG\bin>ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf "drawtext=fontfile= ‘c\\:\\\Windows\\\fonts\\\calibri.ttf':fontsize=18:  fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text='word'" output.mp4
