• ffmpeg gets slow after a while

  19 février 2014, par user3329033

  I have installed ffmpeg on my win r2 server and it gives me headache with rendering videos !
  When i have installed ffmpeg and have started to render videos (700MB mp4 video into 3 clips of 7:00 minutes mp4 videos) it worked pretty good, an 700MB video was rendered in 3 clips in 10 minutes !

  After rendering 30-40 videos in clips it started to slow down, now 1 clip takes 10-20 minutes !

  I have rebooted my machine but it does not change anything, it renders a clip in 10-20 minutes instead of 3-4 minutes !

  I have reinstalled OS and installed ffmpeg again and it works great, it does the rendering in 3-4 minutes but after a couple of videos it slows down again to 10-20 minutes per clip !
  Do you have simillar experience or any suggestions how to avoid the slowdown ?

  My server details are :

  6GB RAM
  4 Cores
  500GB HDD
  Windows Server 2008 R2 Standard OS

• The file upload on server side using multipart file upload

  6 février 2014, par user3217695

  I am trying to upload a file using file upload in java and writing the file to directory in the server side, so the file upload is completed once it's completed the uploaded file is converted to mp4 format so that file can be played in video tag of html5.

  Issue is with the svn file, the new ffmpeg support file are in server side and conversion code is executed it gives me following error.
  What does this error mean ??

  Please help me thanks in advance.
