• 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

• mplayer generating online three thumbnail of video

  5 mai 2013, par soac

  I am trying to create thumbnail of video using mplayer but it is only creating 3 thumbnail of video and then repeating the last thumbnail again and again.

  MPlayer command 1 :

  mplayer video/1.mp4 -sstep 5 -endpos 25 -nosound -vf scale=96:64 -vo jpeg:quality=80:outdir=$tmpPath 2>log.txt

  Problem : It create 3 different image and then repeat last image again and again.

  MPlayer command 2 :

  mplayer video/1.mp4 -sstep 5 -endpos 25 -nosound -frames 5 -vf scale=96:64 -vo jpeg:quality=80:outdir=$tmpPath 2>log.txt

  Problem : It create 3 different image and then repeat last image 2 times, If I change -frames to 10 than it repeat last image 7 times.

  MPlayer command 3 :

  mplayer video/1.mp4 -ss 5 -nosound -frames 1 -vf scale=96:64 -vo jpeg:quality=80:outdir=$tmpPath /
  video/1.mp4 -ss 10 -nosound -frames 1 -vf scale=96:64 -vo jpeg:quality=80:outdir=$tmpPath /
  video/1.mp4 -ss 15 -nosound -frames 1 -vf scale=96:64 -vo jpeg:quality=80:outdir=$tmpPath /
  video/1.mp4 -ss 20 -nosound -frames 1 -vf scale=96:64 -vo jpeg:quality=80:outdir=$tmpPath /
  video/1.mp4 -ss 15 -nosound -frames 1 -vf scale=96:64 -vo jpeg:quality=80:outdir=$tmpPath /
  2>log.txt
  

  Problem : Same problem as above described. 3 thumbnail difference and other are same. Duration of video is 27 seconds. I run this command on mplayer and mplayer2 but same result. MPlayer Binary are taken from http://sourceforge.net/projects/smplayer/files/

  I want MPlayer to capture thumbnail after every X seconds using MPlayer not FFMPEG. I am already using FFMPEG for creating thumbnail and it is working fine. My Operating System is Windows 7. Log File

• Hung out to dry

  Outrage was the general reaction when Google recently announced their dropping of XMPP server-to-server federation from Hangouts, as the search giant’s revamped instant messaging platform is henceforth to be known. This outrage is, however, largely unjustified ; Google’s decision is merely a rational response to issues of a more fundamental nature. … Continue reading →
