  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • Music Video Idiosyncrasies

    18 juin 2011, par Multimedia Mike — General

    So I’m watching a fairly recent music video for a song named "XXXO" from an artist named M.I.A. when I’m suddenly assaulted by this imagery :



    ... and I enter nervous convulsions. You see, while this might seem to be an odd video effect to the casual viewer, to a multimedia hacker, it appears to be deliberately antagonistic. To anyone who has written a video codec, this scene looks like an entire casserole of video bugs, combining creeping plane offsets errors, chroma problems, and interlacing havoc. The craziest part is to realize that this is probably some kind of standard video effect / filter type. Upon a repeat viewing, I realized that the entire video sort of looks like an amateur video editor’s first week using video software.

    Elsewhere in the video, a YouTube-style video frame vortex highlights the proceedings. I guess I need to come to terms with the fact that the ubiquitous player frame is just part of the digital Zeitgeist now :



    Vintage Video Strangeness
    I’m a long-time music video junkie but I have a tendency of examining them entirely too closely. I first saw Paula Abdul’s video for "Cold-Hearted" when I was just starting to understand multimedia technology and how it interacted with emerging home computers. Imagine how confused I was when I tried to make sense of the actions performed by our eMaestro "Chuck" whom Paula has instructed to "hit it". First, he hits a key followed by 3 quick strikes on a second key :



    Then, the "start music" action is apparently bound to a particular key on the electronic keyboard :



    Which kicks off the electronic metronome on the computer. Each identical-sounding beat quizzically maps to a different frequency transform :



    a one...

    and a two...

    and a three...

    I had no trouble believing things up to this point. But even though I didn’t understand what was going on with that frequency transform, I knew that it must have had something to do with the audio. And if the audio was the same, the visualization ought to be the same. Though, to be fair, I will concede that the first and third ticks pictured bear some mutual resemblance.

    Anyway, the software is probably real even if the keyboard interaction was stylized. Can anyone identify the software ? What about the computer ? This is perhaps the best view the video gives us :



    So, remember, don’t base your understanding of technology — or anything, really — on stylized media representations. Don’t even get me started on the movie "Sneakers." That had me confused about cryptography and computer security for many years.

  • Alfresco Content transformation from .avi to *.flv using ffmpeg

    I'm trying to transform diferents video formats into .flv in Alfresco
    I'm using 'ffmpeg' tool to transform content.

  • FFMPEG Undefined Reference to 'avcodoec_open2' in C++

    12 avril 2012, par ALM865

    I have an error when compiling one of my C++ programs after updating the FFMPEG library from 0.8 to 'ffmpeg version git-2012-04-12-277f20c'

    The error I get when I make my program is as follows :

    -------- begin --------
    Linking: Analysing_Server
    ./source/Encoding_Thread.o: In function `CEncoding_Thread::do_work()&#39;:
    /home/Analyser/source/Encoding_Thread.cpp:155: undefined reference to `avcodec_open2&#39;
    collect2: ld returned 1 exit status
    make: *** [Analysing_Server] Error 1

    The relevant lines of my Make file is similar to running g++ as below :

    g++ test2.cpp -lavformat -lavcodec -lavutil -D__STDC_CONSTANT_MACROS

    A stripped down version of my relevant CPP code that throws the error is :

    #include
    #include  

    #define LOG_OUT_STREAM_BUFF_SIZE  200000


    extern "C"  {

         printf("could not open codec");
     }
    }

    Unfortunately the example under 'doc/examples/decoding_encoding.c' that comes with FFMPEG no longer works because all the functions that it uses are now depreciated. My code is based on the example code and worked fine with FFMPEG 0.8 but does not compile with the newest version of FFMPEG. I have changed some of the depreciated functions to their newer versions but it still doesn't compile.

    Does anyone know why I am getting this error ? or does anyone have a link to an example like 'doc/examples/decoding_encoding.c' using the newest version of FFMPEG ?
