  • 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 (...)

  • 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.

  • node js (or other) as streaming server

    20 décembre 2013, par Abdul Ali

    Apologies if a simple question but cannot find anything helpful . Am also new to the streaming concept.

    Goal is to set up a server which keeps on listening for data on a speific port. The user will be sending sequence of images from their iphone (# of images unknown).

    when the data is receieved, ffmpeg should start to get data from that port (as input) and send those images to ffserver to be streamed as a live video.

    did try Nginx-Rtmp module but the iphone developer have informed that in iphone, only ip and port can be given to open a stream (and no other part of the url can be given e.g. streamname and application name in case of nginx-rtmp)

    Any help and guide will be appreciatd that what can be used to set up a free and very simple sever that simply receives the images which ffmpeg can capture and send to ffserver .

  • Conflicting types error using linphone ios sdk

    4 décembre 2013, par VinZ

    I downloaded the linphone sdk for iphone sourcecode and compiled it on my machine. The SDK build was successful after few fixes. But while building the app in Xcode, it is throwing the following error :

    Error 1 :

    /linphone-iphone/submodules/linphone/mediastreamer2/src/utils/ffmpeg-priv.h:78:17: Conflicting types for 'avcodec_alloc_context3'

    Error 2 :

    /linphone-iphone/submodules/linphone/mediastreamer2/src/utils/ffmpeg-priv.h:82:5: Conflicting types for 'avcodec_open2'

    It is coming from mediastreamer2/ffmpeg source code. Any help on how to fix this is highly appreciated.

  • How to write frames to a video file ?

    23 décembre 2013, par Mike Chen

    I am currently writing an application that read frames from camera, modify them, and save them into a video file. I'm planing to do it with ffmpeg. There's rarely a documentation about ffmpeg. I can't find a way. Does any know how to do it ?

    I need it to be done on unix, and in C or C++. Does any can provide some instructions ?

    Thanks.

    EDIT :

    Sorry, I haven't write clearly. I want some developer APIs to write frames to a video file. I open up camera stream, I get every single frame, then I save them into a video file with those APIs available in ffmpeg's public apis. So using command line tool actually doesn't help me. And I've seen output_example.c under the ffmpeg src folder. It's pretty great that I may copy some parts of the code directly without change. And I am still looking for a easier way.

    Also, I'm thinking of porting my app to iPhone, as far as I know, only ffmpeg has been ported on iPhone. GStreamer is based on glib, and it's all GNU stuff. I'm not sure if I can get it work on iPhone. So ffmpeg is still the best choice for now.

    Any comments is appreciated.
