  • 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 (...)

  • 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 (...)

  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • ffmpeg - splitting, overlaying and selecting frame range in multiple input/outputs with complex video filter producing empty output

    11 octobre 2017, par Josep Carner

    I am trying to use ffmpeg to apply multiple filters -single input, multiple outputs-. In concrete, I am splitting the output in two, then applying an overlaying patch to one of those streams, split again and select a time range. The command I am using is :

       ffmpeg \
    
    -i ./dataset_test/videos/jz_10_huron_barstow.mkv \
    
    -an \
    
    -sn \
    
    -loglevel error \
    
    -filter_complex \
    
        "[0:v]split=2[L_in][F_in];
    
         [L_in]
    
            crop=226:307:21:74,scale=200x200,setdar=200:200,split=2\
    
         [L_in_0][L_in_1];\
    
         color=#808080:226x307,setpts=PTS-STARTPTS[L_PATCH];\
    
         [F_in][L_PATCH]
    
            overlay=21:74:shortest=1,scale=200x200,setdar=200:200,split=2\
    
         [F_in_0][F_in_1];\
    
         [F_in_0]select='between(t\,32\,212)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[F_0];\
    
         [F_in_1]select='between(t\,213\,393)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[F_1];\
    
         [L_in_0]select='between(t\,32\,212)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[L_0];\
    
         [L_in_1]select='between(t\,213\,393)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[L_1]\
    
         "\
    
    -map [F_0] -an -sn ./out/jz_10_huron_barstow/F/0_F.mp4\
    
    -map [F_1] -an -sn ./out/jz_10_huron_barstow/F/1_F.mp4\
    
    -map [L_0] -an -sn ./out/jz_10_huron_barstow/L/0_L.mp4\
    
    -map [L_1] -an -sn ./out/jz_10_huron_barstow/L/1_L.mp4\

    For some reason, 0_F.mp4 is empty and 1_F.mp4 is cropped. My intuition is that it has something to do with applying splitting + overlaying + selecting. I think at some point some filter before select is changing the PTS of the frames in some way select is not properly discarding them, but I honestly don’t know how to solve it. Some insights :

    1. L_0 and L_1 are fine (no overlay is used in those two)

    2. If I suppress L outputs everything works fine (no "split" is needed at the beginning)

    Could someone provide some light ? I don’t really know what else to try.
    The logs with loglevel 40 are (some repeated lines ommited) :

    Currently only dc-only and full 16x16. Other subforms will follow in the
    
near future. Total decoding time of ped1080p.webm goes from 9.7 to 9.3

  • Mobile Analytics SDK : beta release of Piwik iOS SDK

    30 octobre 2013, par Piwik team

    Mattias Levin, a Mobile developer enthusiast from Sweden, has released the first public beta version of the official Piwik SDK for iOS !

    If you are building apps for iOS or OSX, you will be able to track your App usage with Piwik. Learn more in this blog post.

    Apps & Mobile apps Analytics

    Using Piwik to track your app usage would give interesting statistics usage such as :

    • number of active users (per day, week, month, …) of my mobile or desktop app,
    • how long users spend in the app,
    • track which icons, buttons are clicked (or any other custom event),
    • record device info, operating system,
    • reports on any Custom Variables you that are relevant to your app (see examples below),
    • how often is the app opened ? When and how long is the app opened ?
    • number of new users, active users, total users,
    • record errors or exception thrown

    Piwik SDK for iOS

    The PiwikTracker is an Objective-C framework (for iOS and OSX) designed to send app usage data to a Piwik analytics server. It is realeased under MIT license. Piwik server is a downloadable, Free/Libre (GPLv3 licensed) real time analytics platform.
