• FFmpeg Drawtext - Fontconfig error : Cannot load default config file : No such file : (null)

  29 mars 2023, par James

  I get the message : Fontconfig error : Cannot load default config file : No such file : (null).
No output is created.

  


  I have installed FFmpeg full version and written this test script to add text onto an image which I drag and drop onto the BAT file.

  


  I searched this database for solutions and found none. The script should produce an output file test.png, The image should have red text on it which reads Hello.

  


  I tried to escape the path to the Font both ways without success :

  


  `set "FONT='c\:\\windows\\fonts\\arial.ttf'" :: Font


  


  `

  


  .. and

  


  `set "FONT='c\:\/windows\/fonts\/arial.ttf'" :: Font`


  


  My full script :

  


  `set "FONT='c\:\/windows\/fonts\/arial.ttf'" :: Font
set "TEXT=Hello" :: Text (no space characters allowed, see next example)
set "COLOR=red" :: Text color
set "SIZE=20" :: Font size
set "POS_X=(w-tw)/2" :: X position of text, use (w-tw)/2 for centering
set "POS_Y=(h-th)/2" :: Y position of text, use (h-th)/2 for centering


ffmpeg -i %1 -vf     drawtext='fontfile=%FONT%:text=%TEXT%:fontcolor=%COLOR%:fontsize=%SIZE%:x=%POS_X%:y=%POS_Y%' -  frames 1 -y test.png


pause`


  


  The complete result :
 C :\Users\canjm\Desktop\Image Correction 360\Archive
Testing\Utilities\Align Photo>set
  
"FONT='c :/windows/fonts/arial.ttf'" : : Font

  


  C:\Users\canjm\Desktop\Image Correction 360\Archive Testing\Utilities\Align Photo>set  "TEXT=Hello" :: Text (no space characters allowed, see next example)

C:\Users\canjm\Desktop\Image Correction 360\Archive Testing\Utilities\Align Photo>set "COLOR=red" :: Text color

C:\Users\canjm\Desktop\Image Correction 360\Archive Testing\Utilities\Align Photo>set "POS_Y=(h-th)/2" :: Y position of text, use (h-th)/2 for centering

C:\Users\canjm\Desktop\Image Correction 360\Archive Testing\Utilities\Align Photo>ffmpeg -i "C:\Users\canjm\Desktop\Image Correction 360\Archive Testing\Utilities\Align Photo\Eqr_360_9999.JPG" -vf drawtext='fontfile='c\:\/windows\/fonts\/arial.ttf':text=Hello:fontcolor=red:fontsize=20:x=(w-tw)/2:y=(h-th)/2' -frames 1 -y test.png
