  flv to mp4 command scaling for latest ffmpeg – what am I doing wrong

  Hi,

  I am trying to convert a flv to mp4 and scaling to 720 pixels wide

  and dont want to set a height as that will stretch the original dimensions.

  ffmpeg -y -i file.flv -vcodec libx264 -preset fast -crf 24 -threads 0 -vf scale="720:trunc(ow/a/2)*2" -acodec aac -strict experimental -ab 256k -ar 44100 file.mp4
