• ffmpeg screenshot ISO Files [closed]

  4 mai 2013, par user1825932

  Hi i try to make screenshot of DVD iso file with ffmpeg. With other file type, like avi or mkv, it work fine. I use ffmpeg with ubuntu 10.4 and
  I use this command :

     ffmpeg -ss 0:05:00 -i /home/Videofile -sameq  -vframes 1 -t 00:00:02 -f image2 /home/image1.png

  But with iso file it's not working.
  Any advice ?

  Thanks

  EDIT
  This is the output :

• No module named 'skvideo.io.ffmpeg' in the project

  12 juillet 2024, par kyobo

  Even though I have installed the scikit-video and installed ffmpeg, I still meet this problem :
  
No module named 'skvideo.io.ffmpeg

  


  Output :

  I have tried to upgrade pip and skvideo but it doesn't work.

  


  How can I solve this problem ?
