  • 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" (...)

  • H.264 adds broken still frames to the end

    14 mai 2015, par Panupat

    I’ve been using ffmpeg to encode raw AVI into H.264 MP4 for about 2 years without problem. However, in my recent project we’re using 60 fps for the first time and face some weird results.

    Here’s an example file. It has 82 frames. FFMPEG would produce the correct result from frame 1 to 82. Here’s a capture at frame 82.

    http://imgur.com/VCIcoVH

    Then, we get this still frame added to the end, from frame 83 to 157.

    Am I doing something wrong in my command ? I tried with almost no options.

    ffmpeg -y -i "C:\tmp\uncompressed.avi" -r 60 -vcodec libx264 "C:\tmp\compressed.mp4"

    Tried a couple different options, the problem still occurs.

    ffmpeg -y -i "C:\tmp\uncompressed.avi" -r 60 -vcodec libx264 -keyint_min 12 -vb 4000k -vprofile high -pix_fmt yuv420p -f mp4 "C:\tmp\compressed.mp4"

    Tried with FFmpeg Win64 Static and Shared build by Kyle Schwarz.

    Appreciate any help, thank you !

  • Installing full multimedia stack on server (ffmpeg,mp4box,sox,mplayer)

    29 avril 2015, par hdezela

    I’ve had a trusty text file with all(?) the steps I need to set up a full multimedia stack on a RHEL compatible server (CentOS, AWS Linux, etc.) for a few years now. However, sometimes some things are missing and I need to revise it. I know it is not complete so I’m asking for suggestions/modifications in order to get a good - and public - list of how to install all this stuff easily.

    Ideally, I want to be able to run through the file and end up with a system that’ll take any media file and be able to convert/encode/decode/whatever with it.

    This is what I have :

    yum install mesa-libGL-devel mesa-libGLU-devel libXi-devel libXmu-devel freeglut-devel freeglut ncurses-devel
    
cd /usr/local/src
    
mkdir /usr/local/src/tmp
    
chmod 777 /usr/local/src/tmp
    
export TMPDIR=/usr/local/src/tmp

  • FFMPEG issues for android lollipop. error : only position independent executables (PIE) are supported

    18 mars 2015, par Arslan Ahmad

    I was using the FFmpeg library in my application from the last 2 years and it still working fine on old version. It wont even work on android lollipop.

    I was using these library before.

    String[] libraryAssets = { "ffmpeg", "libavcodec-55.so", "libavcodec.so",
    
            "libavfilter-4.so", "libavfilter.so", "libavformat-55.so",
    
            "libavformat.so", "libavutil-52.so", "libavutil.so",
    
            "libswresample-0.so", "libswresample.so", "libswscale-2.so",
    
            "libswscale.so"
    

    
    };

    And I have got the answer from other link that if we use these 3 libraries it will work on lollipop aswell

    "liblicense-jni.so,","libloader-jni.so","libvideokit.so"

    But still It didnot resolve yet.
    Please check this log.

     ***Starting FFMPEG***
    
 ***error: only position independent executables (PIE) are supported.***
    
 ***Ending FFMPEG***

    Any help or any update in library ??
