• FFMpeg + Beanstalk : How to pass the processes to it or achieve the same result without using Beanstalk

  6 avril 2017, par Ilia Rostovtsev

  My problem is that FFMpeg and Mencoder are extremely resourceful and running even one process of it makes HTTPd slow down but multiple processes of (FFMPEG /Mencoder) just hang it (HTTPd) completely. I would like my conversions to be processed with Beanstalk, for example.

  My concrete question is : How to transfer my current jobs to Beanstalk ?

  I have a simple PHP code that triggers conversion :

  RunInBackground('convert.php', array($upload, $video_id), $log_path);

  Now what would Beanstalk correct code would look like so these processes would NOT start all at the same time if multiple videos are uploaded ?

  If you believe that for my needs is better to use something else but Beanstalk and you know how to implement it, I would be still happy to see it !

  Thanks in advance,
  Ilia

• Screencasting with hardware-accelerated gnome-3 [closed]

  30 octobre 2012, par Jeroen

  I am running Ubuntu 12.04 with gnome 3 shell, and I would like to create a screencast. I have tried using recordMyDesktop, Kazam Screencaster, and ffmpeg but all suffer from the same problem, which I think has to do with hardware acceleration in Gnome 3. The recorded videos all get very glitchy with blue space for all operations that use some sort of effect. Here is an example recording : http://www.stat.ucla.edu/ jeroen/files/screencast.mkv.

  The only method that does not seem to suffer from this, is the (largely undocumented) CTRL+SHIFT+R shortcut in gnome 3 that will start a recording. However, this feature is very buggy otherwise and often crashes when I enable audio input.

  My machine has a GeForce GT 120 with Apple LED Cinema monitor. I am using the proprietary nvidia drivers that ship with Ubuntu 12.04. Is there any way I can record the video as it appears on my screen ? I know I can avoid the problem by switching to gnome2 or unity 2d or anything that does not use effects, but I would prefer to make the recordings in my regular gnome 3 environment.

• Revision db2b350d33 : Declare setup_buffer_inter in vp9_rdopt.h This funtion initializes buffer point

  10 janvier 2014, par Jingning Han

  Changed Paths :
   Modify /vp9/encoder/vp9_rdopt.c

  
   Modify /vp9/encoder/vp9_rdopt.h

  
  
  Declare setup_buffer_inter in vp9_rdopt.h

  This funtion initializes buffer pointers and first stage motion vector
  prediction. It will be needed by both regular rate-distortion
  optimization loop and the non-RD mode decision. Hence move its
  declaration in vp9_rdopt.h
