  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • Add unique color watermark per frame with FFMpeg

    26 octobre 2018, par Dustin Kerstein

    I’ve been able to add a random color watermark with this code :

    ffmpeg -y -r 100 -i "N%3d.tif" -c:v libx264 -vf "drawbox=y=0:color=random@1:width=8:height=ih:t=fill,scale=1920:1080" -crf 30 -g 10 -profile:v high -level 4.1 -pix_fmt yuv420p test.mp4

    And I know that it’s doable with a script and processing each input frame individually, but I would really like to find a way with FFMpeg to add the watermark during the actual video encoding. It needs to be a unique color per frame. Any ideas on how to accomplish this ?

    Thanks !

  • How to play a part of the MP4 video stream ?

    14 novembre 2014, par AgentFire

    I have a URL (<ip>/ipcam/mpeg4.cgi</ip>) which points to my IP camera which is connected via Ethernet.
    Accessing the URL resuls in a infinite stream of video (possibly with audio) data.

    I would like to store this data into a video file and play it later with a video player (HTML5’s video tag is preferred as the player).

    However, a straightforward approach, which is simple saving the stream data into .mp4 file, didn’t work.

    I have looked into the file and here is what I saw (click to enlarge) :

    It turned out, there are some HTML headers, which I further on manually excluded using the binary editing tool, and yet no player could play the rest of the file.

    The HTML headers are :

    --myboundary
    
Content-Type: image/mpeg4
    
Content-Length: 76241
    
X-Status: 0
    
X-Tag: 1693923
    
X-Flags: 0
    
X-Alarm: 0
    
X-Frametype: I
    
X-Framerate: 30
    
X-Resolution: 1920*1080
    
X-Audio: 1
    
X-Time: 2000-02-03 02:46:31
    
alarm: 0000

    My question is pretty clear now, and I would like any help or suggestion. I suspect, I have to manually create some MP4 headers myself based on those values above, however, I fail to understand format descriptions such as these.

    I have the following video stream settings on my IP camera (click to enlarge) :

    I could also use the ffmpeg tool, but no matter how I try and mix the arguments to the program, it keeps telling me this error :
