  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Que fait exactement ce script ?

    18 janvier 2011, par

    Ce script est écrit en bash. Il est donc facilement utilisable sur n’importe quel serveur.
    Il n’est compatible qu’avec une liste de distributions précises (voir Liste des distributions compatibles).

  • Put a black box image over existing video using ffmpeg

    I am using blob tracker, but have a timecode on video files. I want to overlay a black box over it, therefore preventing the timecode interfering with the tracker.

  • Look for fastest video encoder with least lag to stream webcam streaming to ipad

    16 novembre 2015, par kelly

    I’m looking for the fastest way to encode a webcam stream that will be viewable in a html5 video tag. I’m using a Pandaboard : http://www.digikey.com/product-highlights/us/en/texas-instruments-pandaboard/686#tabs-2 for the hardware. Can use gstreamer, cvlc, ffmpeg. I’ll be using it to drive a robot, so need the least amount of lag in the video stream. Quality doesn’t have to be great and it doesn’t need audio. Also, this is only for one client so bandwidth isn’t an issue. The best solution so far is using ffmpeg with a mpjpeg gives me around 1 sec delay. Anything better ?

  • JavaCV - strange black screen when playing a file with FFmpegFrameGrabber

    17 mai 2012, par noncom

    I am using JavaCV and it's FFmpegFrameGrabber in my project. It loads and player files OK, when I launch the project from Eclipse, but shows either a black screen or a still 1st frame when I run a compiled project. Sometimes comming with this error :

    Input #0, avi, from 'C:/path/Start_Cut.avi':
    
Duration: 00:00:20.03, start: 0.000000, bitrate: 26002 kb/s
    
Stream #0.0: Video: mpeg4, yuv420p, 1920x1080, 30 tbr, 30 tbn, 30 tbc
    
Cannot allocate memory. com.googlecode.javacv.FrameGrabber$Exception: Cannot initialize the conversion c ontext.
    
            at com.googlecode.javacv.FFmpegFrameGrabber.start(FFmpegFrameGrabber.jav a:280)

    and sometimes with

    [mpeg4 @ 6A95DF20] Invalid and inefficient vfw-avi packed B frames detected
    
Input #0, avi, from 'C:/path/Start_Cut.avi':

 tbn, 25 tbc

    does anyone has a clue on this ?

    UPDATE :

    I have been able to narrow down the problem. For some reason, FFmpegFrameGrabber returns null upn calling the grab() method. Why does it work in Eclipse and does not work in standalone build ? All libraries are included and I suppose, it would come up with an error if they did not.
