  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • Prevent libavformat (FFmpeg) from adding "ENCODER" tag to output / help stripping the tags

    9 juillet 2021, par Wyatt Ward

    I made a bash script that transfers audio or video metadata from one file to another, regardless of media container format, via FFMpeg. My problem is that FFMpeg consistently adds a 'ENCODER' tag.

    



    Example :

    



    Before running through FFMpeg :

    



     File : track01.cdda.flac

    



      Metadata:
    ALBUM           : Wish You Were Here
    ARTIST          : Pink Floyd
    COPYRIGHT       : 1975 Harvest Records
    DATE            : 1975
    GENRE           : Experimental Rock
    TITLE           : Shine On You Crazy Diamond
    track           : 1


    



    After running through FFMpeg :

    



     File : track01-iphone-alac.m4a

    



      Metadata:
    ALBUM=Wish You Were Here
    ARTIST=Pink Floyd
    COPYRIGHT=1975 Harvest Records
    DATE=1975
    GENRE=Experimental Rock
    TITLE=Shine On You Crazy Diamond
    track=1
    ENCODER=Lavf55.12.100


    



    So really, I want to either force FFMpeg to not add the 'ENCODER' tag, or I want to strip that tag off afterwards. Is there a way to do this ? I really don't want to spend hours trying to compile FFMpeg again on my Pentium 4 HT - the only working computer I have at the moment. I'd prefer not to have to use another program unless it's related enough to FFMpeg or MPlayer/Mencoder that I won't have to install anything new if I have those installed.

    


  • Play video files online sequentially without delay/buffering between videos

    26 février 2015, par Marko

    Is it possible to play video online that’s made of two or more video files ?

    Since my original post wasn’t clear enough, here’s expanded explanation and question.

    My site is hosted on Linux/Apache/PHP server. I have video files in FLV/F4V format. I can also convert them to other available formats if necessary. All videos have same aspect ratio and other parameters.

    What I want is to build (or use if exist) online video player that plays video composed of multiple video files concatenated together in real-time, i.e. when user clicks to see a video.

    For example, visitor comes to my site and sees video titled "Welcome" available to play. When he/she clicks to play that video, I take video files "Opening.f4v", "Welcome.f4v" and "Ending.f4v" and join/merge/concatenate them one after another to create one continuous video on the fly.

    Resulting video looks like one video, with no visual clues, lags or even smallest observable delay between video parts. Basically what is done is some form of on-the-fly editing or pre-editing, and user sees the result. This resulting video is not saved on the server, it’s just composed and played that way real-time.

    Also, if possible, user shouldn’t be made to wait for this merging to be over before he/she sees resulting video, but to be able to get first part of the video playing immediately, while merging is done simultaneously.

    Is this possible with flash/actionscript, ffmpeg, html5 or some other online technology ? I don’t need explanation how it’s possible, just a nod that it’s possible and some links to further investigate.

    Also, if one option is to use flash, what are alternatives for making this work when site is visited from iphone/ipad ?
