SOLVED - FFMPEG 'Fontconfig error : Cannot load default config file' error Windows
27 février 2019, par MerelI 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.mp4However, 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

Is there a way to program the (Download) button to save a group of images as a one video ?
9 février 2024, par Lina Al-fawzanThis is my entire code. Its function is that everything the user writes or says will have images returned to him according to what he wrote/said, and the next image will be shown to him after he presses “close,” and he can save each image separately. I want to make a simple modification to it. First, instead of a close button, I want each image to be displayed for 3 seconds and the next one to be displayed, and so on... “all of them in one window”, and for the “download” button to be when the last image is displayed, and for them all to be saved in one video.

How to bold a font in ffmpeg ?
28 février 2023, par Peter.kI have an issue which I don't fully understand. I use font to merge subtitles in video which is installed in my laptop and everything works fine with this code :


-vf "subtitles=tt101.srt:force_style='FontName=Lucida Console,Style=Bold,FontSize=15,PrimaryColour=&H00111188,OutlineColour=&HFFFFFFFF,BorderStyle=4,BackColour=&H44FFFFFF,Outline=5,Shadow=0,MarginV=10'"


But later I found this font isn't really bold but regular. I checked in my system and indeed, there's no bold version installed, so this
Style=Boldfragment is ignored (as I think it is). But how the hell, while using this very font in some other programs like Word, Excel, Photoshop, PotPlayer, etc, I am able to bold this font anyway ? Whyffmpegdoesn't make it ? Does these programs use something else than Windows show in the Font catalog ?
