  • 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 (...)

  • MediaSPIP Init et Diogène : types de publications de MediaSPIP

  • Flutter FFMPEG : Error setting profile baseline

    9 avril 2021, par Raj Dhakad

    Flutter-ffmpeg unable to set profile parameter. (I need to use profile so the rendered video can be played on WhatsApp).

    


    I am converting.bmp images into a mp4 video. Other I have tested other praramets and the work great it's only -profile:v which seems to have some problem.

    


    Everything works fine unless I use -profile:v baseline.

    


    void _runFFmpeg() async {
    var dir = await getApplicationDocumentsDirectory();
    var output = await getExternalStorageDirectory();
    String videoSize = '${ImageWidth}x$ImageSize';
    print("${ImageWidth}x$ImageSize");
    var arguments = [
      "-y", // replace output file if it already exists
      "-framerate", "30", // framrate
      "-video_size", videoSize,
      "-pixel_format", "yuv420p",
      "-i", "${output.path}/frame_%d.bmp",  
      "-profile:v", "baseline",
      "-level", "3.0",
      "${output.path}/test.mp4"
    ];
    
    _flutterFFmpeg
        .executeWithArguments(arguments)
        .then((rc) => print("FFmpeg process exited with rc $rc"));

    The resultant video can play the first part of the video correctly, then the video players either skips directly to the end of the video (MPC-HC), or don't render anything at all while timer passes as normal (VLC).

    


    My impression of the concat is that it requires all videos to have the same spec, which I think my input achieved (all the "Steam #0:0", etc, line matches). I only see the following difference, which I assumed that should be okay :

    


      

    1. Metadata are different both for the whole input (e.g. "major_brand") and for each stream (e.g. "encoder"). I assumed that metadata won't affect the processing.
    2. 


    3. The order of video/audio streams are different in the two inputs : the 1st input file has audio then video ; the 2nd input file has video then audio. I assumed that ffmpeg knows the difference and won't concat a video stream to an audio stream.
