  I tried with other stackoverflow questions but none of them worked. Also I think it is partially because the trim timings are mixed. That is start time can be anywhere between 0-end. When I make it strictly increasing it is working fine.

• ffmpeg error : "Missing ')' or too many args in 'if(gt(a,1),650,-1)'"

  23 février 2015, par Remini me

  I am trying to run this ffmpeg command in linux shell, to scale down the video (if portrait, than to maximum height of 650, while adjusting the width. And if landscape, then 650 maximum width, and adjust the height with aspect ratio) :

  ffmpeg -i 1.mp4 -r 30 -vf scale="'if(gt(a,1),650,-1)':'if(gt(a,1),-1,650)'" -vcodec libx264 output_file1.mp4

  But I get the following error :

  [scale @ 0x1d48a40] [Eval @ 0x7fff53a49340] Missing ’)’ or too many
  args in ’if(gt(a,1),650,-1)’ [scale @ 0x1d48a40] [Eval @
  0x7fff53a49340] Missing ’)’ or too many args in ’if(gt(a,1),-1,650)’
  Error when evaluating the expression ’if(gt(a,1),-1,650)’

  **EDIT : I have tried using the new @slhck syntax :

  -vf "scale=if(gt(a\,1)\,650\,-2):if(gt(a\,1)\,-2\,650)"

  The result I got was :
