• Ffmpeg command to most efficiently merge mp3 audio file and jpeg image file to a video file [closed]

  25 juin 2020, par Eugen

  I'm looking for an efficient way to merge a large .mp3 file and a single .jpg image to a video format for youtube. If I use :

  



  ffmpeg -loop 1 -i image.jpg -i audio.mp3 -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest output.mp4


  



  the result is very slow, especially for large .mp3 files. Is it possible to do it more efficiently with ffmpeg ? I know there must be a way to do it much more efficiently, like all the online converters are doing it.
