  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

    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.

  • Best and latest live video streaming soloution [on hold]

    3 avril 2015, par Ford

    I have read a few old posts on StackOverflow about live video streamins, but as they are from around 2008, i assume things have moved on from then... and wonder if a current thread will be useful to me and others.
    Also looking on google gives lots of stuff, but again i dont know who is best to listen to and who is trying to sell their stuff (not that i am against paying).

    Basically what are the main points i need to know in order to add/develope a feature to a website in order to offer "1 on 1" and "1 to many" MULTIPLE live streaming webcam, with voice and text chat.

    I am quiet competent with PHP, OK with basic JavaScript (of course fine with HTMLL/css), but do not know what code i would need for client side software, or if any "off the shelf" software is suitable.
    I have played with ffmpeg and noticed this offers streaming, but i dont know if it would be suitable or the best available option.?
    I have a dedicated server with virtualization so can add a dedicated box for streaming if needed/better.

    Any info that can point me off in the right direction of how to add a live streaming service to a website would be much appreciated !

  • Mozilla Firefox 36 has problems playing my h264 MP4 files

    11 juin 2015, par Wolfgang Pürstner

    I try to convert videos with ffmpeg to mp4 format (h264) Profile : High Level : 3.1 (1280x720 with 30fps), Bitrate 1500k

    The video plays very well in every browser except in Firefox.

    http://5.79.72.89/trailer/trailer.mp4

    At first it needs longer to load and when I seek inside the video most times the video don’t stop to load and never plays again.
    I can see a lot of partial downloads in the developer console. A lot of them are for the initial play and the rest of the requests are during the video load when I seek to a later position.

    enter image description here

    When I play other h264 Videos (MP4 with similar settings) they play without problems on this server.
    And when I put my video on another webserver (apache) there are the same problems with Firefox.

    For this reason I believe it has to do something with me my conversion.

    My settings :
    Debian 7 (wheezy)
    Webserver : nginx (with 260k bandwidth limit)

    I started converting videos with avconv and switched to ffmpeg because of this problems. But there was no success.
    Meanwhile I tried all options for encoding but there are always the same problems with Firefox. Other videos play well but not mines and I don’t know why.

    Command :

    ffmpeg -i input.mp4 -tune zerolatency -x264opts bitrate=1500:vbv-maxrate=1500:vbv-bufsize=3000:nal-hrd=vbr -codec:v libx264 -profile:v high -level 3.1 -movflags +faststart -pix_fmt yuv420p  -s 1280x720 -r 30 -ac 2 -ar 48000 -codec:a aac -ab 64k -strict experimental -y trailer.mp4

    I updated ffmpeg to 2.6. I used libfaac, aac and libfdk_aac for audio encoding with cbr and vbr but without success.

  • Evolution #2798 : Notification mise à jour SPIP

    9 avril 2015, par b b

    Et hop, voici le patch à jour avec la proposition de Cedric.

    Reste à améliorer le lien. Je pense qu’on pourrait mettre en place sur spip.net une page dont le fonctionnement serait similaire à celle des téléchargements avec une url comme http://www.spip.net/fr_update

    Pour cela, il faut créer un article en fr (pour commencer) qui reprend les propositions de Nicolas par ici :

    http://www.spip.net/ecrire/?exec=rubrique&id_rubrique=151

    Puis modifier le squelette pour qu’il prenne en charge l’url /xx_update par ici :

    http://zone.spip.org/trac/spip-zone/browser/_galaxie_/www.spip.net/squelettes/branches/2008/urls/trad.php#L8

    Ça vous semble convenable ? gogogo ?
