• Creating animated AVIF with FFmpeg

  17 septembre 2022, par Ollie Williams

  Edit : This did eventually complete, and the output file is fine. I am using a top-end MacBook M1 Pro computer. Is it normal for it to be this relentlessly slow ? It was

  


  My input file is an .mov. I used this command :

  


  ffmpeg -i Jellyfish.mov Jellyfish.avif

  


  I also tried converting an MP4/h264 file.
In both cases it took over 50 minutes.

  


  It's a 5 second long clip but it has taken about 20 minutes and the output file is still zero bytes.

  


  This is the output in my terminal :

• How to fix muxer does not support non seekable output error on ffmpeg ?

  19 septembre 2022, par Yusuf

  I am getting this error when I try to stream my video to YouTube rtmps server and I don't know what it means or how to fix it. Can anyone help ?

  


  I first record my screen with Electron's MediaRecorder

  


  then I insert metadata of to the blob (othervise Electron exports without specifying the end of the file)

  


  I convert the webm to mp4 by executing
ffmpeg -i ${tempVideoPath} -c copy ${tempMp4VideoPath}

  


  Then I execute
ffmpeg -re -i ${tempVideoPath} -c copy -f mp4 ${youtubertmpslink}

  


  Finally I get this error :
