  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

    12 avril 2011, par

    La manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
    Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

  • Que fait exactement ce script ?

    18 janvier 2011, par

    Ce script est écrit en bash. Il est donc facilement utilisable sur n’importe quel serveur.
    Il n’est compatible qu’avec une liste de distributions précises (voir Liste des distributions compatibles).
    Installation de dépendances de MediaSPIP
    Son rôle principal est d’installer l’ensemble des dépendances logicielles nécessaires coté serveur à savoir :
    Les outils de base pour pouvoir installer le reste des dépendances Les outils de développements : build-essential (via APT depuis les dépôts officiels) ; (...)

  • Playing videos on iPhone after video conversion using ffmpeg

    12 juillet 2013, par Shashi

    It is a backend API(developed in Ruby on Rails) which is used by iphone and android mobiles to upload the videos. API is converting uploaded videos to MP4 format. I am using paperclip-ffmpeg gem for video conversion at backend. Here is what I used :

    has_attached_file :video ,
                 :styles=>{
                   :medium=>{ :geometry=>"480x360",:format=>'mp4',:streaming => true,
                       :convert_options => { :output =>
                                           {
                                             :acodec => 'aac',
                                             :ac => 2 ,
                                             :strict => 'experimental',
                                             'b:a' => '160k',

                                             :vcodec => 'libx264',
                                             :preset => 'slow',
                                             'profile:v' => 'baseline',
                                             :level => '30',
                                             :maxrate => '10000000',
                                             :bufsize => '10000000',
                                             'b:v' => '750k',
                                             :f => 'mp4',
                                             :threads => '0'
                                           }
                                       } },
                     :thumb => { :geometry => "160x120", :format => 'jpg', :time => 2 },
                     :thumb_large => { :geometry => "520x390", :format => 'jpg', :time => 2}
                   }, :processors => [:ffmpeg, :qtfaststart],
           :path => path/to/store/video,
           :url => url/of/video

    Problems I am facing are :

    When user uploads videos from android mobile it works perfect on android but does not play on iPhone. One more strange thing happens when user upload videos from iPhone, then it play perfect just after video upload, but after some time(2 or 3 hours) it stops to play those videos.

    How can I get rid of both these issues ? Any suggestion would be appreciated. Thanks

    @Michael, here is the detailed log for the video conversion uploaded by android mobile

  • Creating .flv files on the iphone without using ffmpeg

    15 mars 2014, par inwit

    How does one create .flv files on the iPhone ?

    I am aware of ffmpeg (with its LGPL restrictions). But are there other APIs that have been ported to iOS ?

  • IP-Cam / CCTV-Cam Live Streaming on iPhone/iPad

    19 mai 2013, par user1744691

    I want to get stream of an ip-cam on my iPhone/iPad and want to display it on screen. By R&D i found that ffmpeg is the only way to achieve it but i found nothing on ffmpeg. Is there any other way to achieve it or a confirmed way to get compiled ffmpeg on mac please mention that. Material regarding how to use ffmepg or source code example will be highly appreciated.

    Is there nothing built-in framework to achieve it if not then please mention if there is any free framework/sdk to achieve this functionality.

    Thanks
