  22 mai 2013, par Mans — Law and liberty

  Reading about various patent litigation cases, I am struck by the frequency with which common logical fallacies such as the Appeal to Consequences are committed. We shall look at a couple of recent examples. In conjunction with the Federal Circuit ruling in CLS Bank v. Alice Corp., Judge Moore, joined … Continue reading →

• Hung out to dry

  31 mai 2013, par Mans — Law and liberty

  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.

• 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
