• 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

  avcodec/x86/videodsp : Small speedups in ff_emulated_edge_mc x86 SIMD.
  Don’t use word-size multiplications if size == 2, and if we’re using
  
  SIMD instructions (size >= 8), complete leftover 4byte sets using movd,
  
  not mov. Both of these changes lead to minor speedups.

• wrong ffmpeg version for xuggler

  13 décembre 2011, par kerel

  I am trying to get Xuggle working on Ubuntu.
  This is however my first time using a Unix system.

  After installing Xuggle and correcting the PATH files I tried some very simple code from tutorials at the xuggle website. But once I attempt to debug my code, it stops and eclipse says

  Suspended (exeption IllegalArgumentException)

  and refers to line 488 of MediaReader.readPacket()

  After searching possible explanations I found that my FFMPEG version was not the version Xuggle needs. When I test my FFMPEG version from command line with
  $ ffmpeg /invalid/file/ it displays --extra-version='4:0.7.2-1ubuntu1' but according to the xuggle site the --extra-version= should include the word "xuggle". Following their installation procedures does not change anything.

  I downloaded the source code from SVN, which includes a ffmpeg folder. I assume this is the ffmpeg version I need. I have no clue however what to do with this folder.

  question is : how do I get my ffmpeg version to the xuggle compatible ffmpeg version ?
