• 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

• How to config FFmpeg for xrgb and Aver Media capture card [closed]

  12 mai 2023, par Plotter Desalor

  I'm trying to use FFmpeg through ffplay to display a capture card output as lossless as possible.

  


  My capture card is named "Live Gamer Ultra-Video"

  


  In OBS, the NV12, YV12, P010 and YUY2 lead to blurriness around text and fine pixels edges, but the XRGB one offer clear output. So I've tried to focus on this mode with FFmpeg as the default one lead to same blurriness seen in OBS.

  


  Running "ffmpeg -f dshow -list_options true -i video="Live Gamer Ultra-Video" show me this result
(i've only kept line with wanted resolution)

video=Live Gamer Ultra-Video: Immediate exit requested


  


  "unknown compression type 0xE436EB7D" is a pretty bad start but from https://trac.ffmpeg.org/ticket/6279 I could figured out it was just unproperly parsed RGB24 format

  


  But if I run a very simple "ffplay -f dshow -i video="Live Gamer Ultra-Video" -pixel_format rgb24"
I got this output

  How could I use rgb format with this capture card ?

  


  If not possible, any other format leading to proper output would be ok too.
I've tried parameters from this topic Capture full-range/lossless rgb frame from capture card that supports NV12 and YUYV output without any good result sadly.
