  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • 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.

  • Create video from series of images using android

    15 septembre 2014, par Farrakh Javed

    I’m trying to write an android application in which we allow user to create video from series of images.
    I did lot of investigation like C/C++ libraries FFMPEG, X264. These can be used using NDK, but i dont know how to use it via NDK, i also did investigation but did not get about this.
    I find another library JCodec It is java based. I tried different codes of JCodec but did not get any success. Below are Links related to JCodec :

    this,
    this and this.

    Now can anyone guide me about this question and can i have some suggestion how to implement this feature.

  • How to encode a series of .dpx files using X264

    4 juin 2015, par user3759710

    I am complete newbie to video encoding. I am trying to encode a series of .dpx files into one single encoded video O/P file in any of the following format. ( .mp4,.avi,.h264,.mkv etc)

    I have tried 2 different approaches. The first one works and the second one does not.
    I would like to know the difference between the two. Any help / input would be much appreciated.

    1) using FFMPEG along with x264 library and it works well. I am able to produce desired output

    ffmpeg -start_number 0 -i frame%4d.dpx -pix_fmt yuv420p -c:v libx264 -crf 28 
    
-profile:v baseline fromdpx.h264

    2) I first try to concatenate all the dpx files into a single file using concate protocol in ffmpeg and then use x264 to encode the concatenated file.
    Here I see that the size of the concatenated file is the sum of all the files concatenated. But when I use x264 command to encode the concatenated file, I get a green screen (basically not the desired output) .

    ffmpeg -i "concat:frame0.dpx|frame01.dpx|frame2.dpx etc" -c copy output.dpx

    then

    x264 --crf 28 --profile baseline -o encoded.mp4 --input-res 1920x1080 --demuxer raw 
    
output.dpx

    I also tried to encoded the concatenated file using ffmpeg as follows

    ffmpeg -i output.dpx -pix_fmt yuv420p -c:v libx264 -crf 28 -profile:v baseline fromdpx.h264

    This also gives me a blank video.

    Could someone please point out to me what is going on here ? Why does the first method work and the second does not ?

    Thank you.
