• FFMpeg keep audio when adding date/time to video file

  19 juillet 2018, par user567424

  We have a video file we have recorded and have the ffmpeg script below which adds the date/time to it. However, the output file video loses the audio part. How do we get it to pull that over from the input video file as well, so the audio stays in place ?

  ffmpeg.exe -y -i "input.mp4" -ss 00:00:00 -t 00:02:17 -an -vcodec libx264 -profile:v baseline -level 13 -b:v 2000k -vf "drawtext=fontcolor=white:fontsize=16:fontfile="/Windows/Fonts/arial.ttf" :\text=12-07-2018— : box=1:boxcolor=black@0.3:x=(w-text_w-10):y=(h-text_h-5):timecode=’ 14:36:47~;00’:rate=30000/1001" output.mp4

• no such file or directory in ffmpeg when trying to convert mkv to mp3

  1er août 2018, par Kreation

  $in_path = "H:\Music\Spotify Music conversion\conversion 2018";
  
  $out_path = "H:\Music\Spotify Music conversion\conversion 2018";
  
  
  
  for /R %f IN (*.mkv) DO ffmpeg -i $in_path -c $out_path\%~nf.mp3

  this script is supposed to convert all the mkv files in the input path to mp3, however when I try and run it, I get : $in_path: No such file or directory
