• 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

• Images to video in Prezi format

  13 juin 2016, par sammy34

  I have five *.jpeg image files : m01.jpeg to m05.jpeg.

  I’d like to make a video of a sequence of these five images and upload it to Prezi to use in a presentation.

  FFMPEG seems to be the tool for the job here. I am generating a video using the following command :

  ffmpeg -r 2 -i m%02d.jpeg -pix_fmt yuvj420p myvideo.mp4

  This generates a video that I can play fine locally. Unfortunately, when I try to upload the video to Prezi, I always get the following error...

  "Technical details: id: 2110 the reason is: Event [Event type="stateChange" bubbles=false cancelable=false eventPhase=2]"

  ...which isn’t particularly informative.

  If I upload a sample MP4 from the web to Prezi, it works fine.

  My question : Does anybody know what I need to give FFMPEG as parameters here so that it will generate a Prezi-compatible video from these images ?

  EDIT : As requested, here’s the complete console output for FFMPEG. Unfortunately there are no glaring warnings or errors that I can see.

• FFMpeg - Split Window RTMP - Delay on Second Stream

  22 février 2016, par Nick Smit

  I’m trying to combine two live RTMP sources into one split screen output with combined audio. The output is then sent on to a receiving RTMP server.

  Using the following command, which uses the same RTMP input for both feeds, I’ve managed to get the above working, however the input on the left is delayed by about 2 seconds from the one on the right.

  ffmpeg -re -i rtmp://myserver.tld/live/stream_key -re -i rtmp://myserver.tld/live/stream_key \
