• fluent ffmpeg how to set X11 display as input

  3 novembre 2018, par direxit

  With command line i can easily capture an Xserver display, trying to reproduce this with fluent-ffmpeg for node

  videoCommand.addInput(':99.0+0,150')
  
  .withSize('720x480')
  
  .withFpsInput(60)
  
  .withFpsOutput(60)
  
  .addInputOption('-y', '-f x11grab')
  
  .outputOptions(['-c:v libx264', '-crf 18' , '-preset veryfast' , '-t 
  
   00:00:05'])
  
  .output(base_path+'/video.mp4')
  
  .run();

  I get

  Unrecognized option 'f x11grab'.

  I am concerned about the syntax or way to set the input as DISPLAY :99.0
  and also to tell ffmpeg that i want x11grab.

  Where those has to be set ?

  --- EDIT ---

  changed to .addInputOptions(’-y’, ’-f x11grab’)
  with ’s’

  same error
