  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Shared Hosting + Static FFMPEG + PHP (or other scripting language) == failure on finding codec

    7 juillet 2012, par Ethan Allen

    here is the following environment :

    1. 1and1 shared hosting (they do not have ffmpeg installed, all good)
    2. i built a static ffmpeg binary that does not require dynamic loading of shared libaries (i built this on an Ubuntu system)
    3. ffmpeg binary is fully accessible and is able to get access
    4. executing the same command terminal or executing a php/perl script via terminal works fine...however, both scripts through a browser/web request fails with the following :
        Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

    Any help appreciated, thanks !

  • ffmpeg integration with Codeignitor [on hold]

    14 novembre 2016, par Nomi

    I am working on a project which have the following requirements...

    1. It should upload a video .
    2. then it should verify what type of video file it is i.e flv ,mp4
      etc.
    3. it should also configure its resolution according to our needs.
    4. and then finally save it into a database.

    I have been searching the possible solution for this and learned that ffmpeg could be a solution.But i haven’t been able to learn how to code it.
    Can Somebody please guide me on how to install ffmpeg with Codeignitor from scratch OR some other library which could serve the same purpose .

  • Trying to use FFMPEG for android. Compiling but still not working

    15 avril 2014, par Austin Mueller

    So to start off... Im trying to use ffmpeg to compile an array of images into a video on Android.

    I have followed a variety of tutorials online and have gotten as far as being able to compile the lib for Android and still have to project run.
    The repo im now using can be found here : https://github.com/Batterii/android-ffmpeg-x264

    I made a couple tweaks to the setttings.sh just to correct ndk location. Besides that, I followed the instructions and it seemed to work flawlessly.

    After that, I converted the "Project" project into an Android stdio library module.
    Screenshot of android studio module

    I am not getting any compile errors, nor am I getting any runtime errors, or any other errors that I can detect... Nothing on logcat... But I am definitely not getting any video called out.mp4.
    In an onCreate of a particular activity, I am running this code :

    Videokit vk = new Videokit();
    
vk.run(new String[]{"ffmpeg", "-r", "1/5", "-i", "%d.jpg", "-c:v", "libx264", "-r", "30", "-pix_fmt", "yuv420p", project.getProjectDirectory() + "/out.mp4"});

    This command is taken from the command line example found here :
    https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images

    Thank you in advance for anyone taking the time to look through this post... I am pretty baffled at this point, as there are no errors I can find and no video...
    Thanks

    Turns out it is not actually compiling correctly... but i have found a few things.

    I've been messing around with it for a couple hours now and pretty much every time, i get gradle yelling at me about the fact that it can't find some file. I'm beginning to think that maybe it is because my LOCAL_LDLIBS aren't in the same order as the original...? Im not entirely sure... Does anyone else have any ideas...?
