  iam using windows 10, last version of ffmpeg, so what makes this problem. also how to make the style of the lyrics to be something like fade in/out and so on. if it’s possible
  Thanks in advance.
  update
  when i use this command

  ffmpeg -loop 1 -y -i test.jpg -i test.mp3 -vf "subtitles=test.srt:force_style='FontName=Arial,FontSize=14'" -shortest test1.mp4

  it give me this error

  Conversion failed!

  i searched this error and i found a solution by add this part before output file so the final command is

  ffmpeg -loop 1 -y -i test.jpg -i test.mp3 -vf "subtitles=test.srt:force_style='FontName=Arial,FontSize=14'" -shortest -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" test1.mp4

  i got no error and it worked but the output video not contains any lyrics which i added

  Update
  
  last thing i tried and it works first i use this command to convert the image and mp3 file to a mp4 video

  ffmpeg -loop 1 -i test.jpg -i test.mp3 -shortest -acodec copy -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" video.mp4

  but this command take a long time to process to convert mp3 of 2:55 minute it with image.
  then i start to add lyrics or subtitle using this command

  ffmpeg -i video.mp4 -vf "subtitles=test.srt:force_style='FontName=Arial,FontSize=14,PrimaryColour=&H0000ff&'" -c:a copy output.mp4

  this worked perfect and give the output but it take a long time to process i don’t know if this normal.
  now last thing how can i set the style of the subtitle so it be fade out or something
