  13 août 2016, par Magurean Dan Sergiu

  I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

• Ffmpeg Command to capture video from Decklink 4k Extreme in Ubuntu Linux

  24 septembre 2016, par George.Ef

  I am trying to capture a video using ffmpeg, from the HDMI input port of the Blackmagic DeckLink 4K Extreme capture card in Ubuntu Linux.

  As per the ffmpeg Documentation I have tried the following :

  ffmpeg -f decklink -video_input 'hdmi' -i 'DeckLink 4K Extreme (1)@14' -acodec copy -vcodec copy ~/testCapture/card1_f14_hdmi.avi

  but no matter what I do I always get this picture as a video
  

  My ffmpeg version is :

  DeckLink 4K Extreme (1): Immediate exit requested

  What should I use with ffmpeg in order to capture an HD video with sound from the HDMI port ?

• Golang command working in terminal but not with exec package

  17 août 2016, par Jon Stevens

  I am converting a video generation library from NodeJS to GO that primarily uses FFMPEG for all the video processing. I already have all the FFMPEG commands written out to do the generation I want. The issue is that when I try to run the command through the os/exec package, it fails. However, if I copy the exact command and run it directly in the terminal it works and I cannot figure out why that is. My code that runs the command is below :

  command := "ffmpeg -y -loop 1 -i image.png -vf 'fade=in:0:15,fade=out:105:15' -c:v mpeg2video -t 5 -s 1280x720 -r 30 -q:v 1 -preset ultrafast image.mpg"
  
  
  
  parts := strings.Fields(command)
  
  cmd := exec.Command(parts[0], parts[1:]...)
  
  cmd.Stderr = os.Stderr
  
  cmd.Stdout = os.Stdout
  
  err := cmd.Run()
  
  if err != nil {
  
      panic(err)
  
  }

  The ffmpeg error I get when I try to run this code is :

  [AVFilterGraph @ 0x22a9bc0] No such filter : ’fade=in:0:15,fade=out:105:15’

  Error opening filters !

  2016/08/17 17:48:53 exit status 1

  Like I previously stated, if I copy the EXACT command :

  ffmpeg -y -loop 1 -i image.png -vf 'fade=in:0:15,fade=out:105:15' -c:v mpeg2video -t 5 -s 1280x720 -r 30 -q:v 1 -preset ultrafast image.mpg

  and run it directly in the terminal, it works no problem.

  PLEASE HELP.
