  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
    Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...)

  • 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 (...)

  • Evolution #4042 : Forums : pouvoir les reoodonner

    28 septembre 2018, par cedric -

    Réordonner est un peu too much, mais rattacher un message à un autre (le déplacer de thread donc) serait utile en effet
    (et ça peut être une interface simple avec saisie d’un id_message parent dans le back office)

  • Dreamcast Development Desktop

    28 mars 2011, par Multimedia Mike — Sega Dreamcast

    Some people are curious about what kind of equipment is required to program a Sega Dreamcast. This is my setup :



    It’s a bit overcomplicated. The only piece in that picture which doesn’t play a role in the Dreamcast development process is the scanner. The Eee PC does the heavy lifting of development (i.e., text editing and cross compilation) and uploads to the Dreamcast via a special serial cable. Those are the most essential parts and are really the only pieces necessary for a lot of algorithmic stuff (things that can be validated via a serial console). But then I have to go up a level where I output video. That’s where things get messy.



    The Mac Mini and giant monitor really just act as a glorified TV in this case. Ideally, it will be more than that. The DC outputs audio and video via composite cables to a Canopus DV capture bridge. That’s connected via FireWire to the external hard drive underneath the Mac Mini, which is connected to the Mac. Adobe Premiere Pro handles the DV capture / display.

    One day I hope to have something worthwhile to capture.

  • ffmpeg link error with CodeBlocks

    12 juillet 2016, par Yoohoo

    Hi，I am currently doing a real time video encoding c program using ffmpeg, initially I encountered a lot of "undefined reference" error, after I set the linker in build options, some error got disappeared, but still some error remains.

    Here are my screen shot of the CodeBlock linker setting.

    ffmpeg_build/lib/libvpx.a
    
ffmpeg_build/lib/libswscale.a
    
ffmpeg_build/lib/libwresample.a
    
ffmpeg_build/lib/libpostproc.a
    
ffmpeg_build/lib/libfdk-aac.a
    
ffmpeg_build/lib/libvutil.a
    
ffmpeg_build/lib/libvformat.a
    
ffmpeg_build/lib/libavfilter.a
    
ffmpeg_build/lib/libavdevice.a
    
ffmpeg_build/lib/libavcodec.a

    Totally 10 libs.

    My Questions :

    1. Are these errors caused by lacking libs or libs not linked.
    2. What libs I missing or what libs should I add to linker.
