  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • 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 (...)

  • Keeping control of your media in your hands

    13 avril 2011, par

    The vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.

    MediaSPIP is designed to facilitate the sharing of creative media online, while allowing authors to retain complete control of their work.
    MediaSPIP aims to be accessible to as many people as possible and development is based on expanding the (...)

  • RTSP/RTMP Video Streaming Client iOS [closed]

    28 mai 2015, par nathansizemore

    I’m in need of a open source solution/library to stream RTSP/RTMP to an iOS Application. I need to build an app that connects to a media server, and opens the provided video stream. I believe there has to be libraries out there, but I have yet to find one that is open source, compiles, actually works, and runs on iOS 5+, iPhone 4+. I do not have a preference, RTMP or RTSP will suffice. Preferably the one with the least amount of work. I have RTSP working on the Android side, but nothing for iOS yet.

    This is what I already know from research today -

    RTSP

    • Seems possible using Live555/FFMPEG
    • MooncatVenture Group - Old FFMPEG, not compatible with ARMv7s (No updates/blogs/commits in over a year)
    • DFURTSPPlayer - This is a working example.

    RTMP

    • Seems possible using Live555/FFMPEG
    • A few libraries are out there for data messaging, but that is all
    • MidnightCoders Project - Does not seem video support is build yet, as Audio is not.

    I’ve never messed with anything video related before, so encoding, frame rate, key frame, chunks, etc... is pretty foreign to me. Right now, it seems building a static binary from Live555/FFMPEG is the only solution to my problem. If so, can anyone give me a simple quickstart guide or links to a blog/example someone has out there ? I’m not looking for anything crazy, just a simple

    1. Download This - LINK
    2. Compile it like this - LINK
    3. Place it into X Folder in Xcode
    4. Create X Object
    5. Read Stream API here - LINK

    If not, anyone want to point me to a working open source library ?

    Oh yeah, this happens to be my first iPhone app and first time in Objective-C. Awesome first project, yeah ?

  • Timelapse (1/6 fps) from slo-mo (240 fps) with ffmpeg

    4 avril 2022, par baskak

    I recorded slo-mo video on an iPhone SE (2) by mistake instead of timelapse.

    


    I know there's a lot of answers to this question here, but I'm trying again and again and always something's wrong (like a video that has a correct total no. of frames, but lasts 3 hours and is basically a freeze :D )
My recent command was

    


    


    ffmpeg -i IMG_2174.MOV -vf framestep=1440,setpts=N/120/TB -c:v libx264
-preset slow -crf 22 -an -r 30 IMG_2174.timelapse.MOV

    


    


    but it resulted in a one-second-long video, so way over-timelapsed. Should be several seconds IINM. The source video is 30 minutes long @240fps, 17GB.
Thx.

    


  • AudioQueue bytes to ffmpeg understandable WAV format

    24 décembre 2015, par moeseth

    I got the recorded AudioQueueBufferRef buffer using the following code.

    NSData *data = [NSData dataWithBytes:inBuffer->mAudioData length:inBuffer->mAudioDataByteSize];

    And then, I send the data to my server. However, FFMPEG isn’t able to read that because the data is not in any audio standard format.

    It’s just plain data.

    So, how do I do either on iPhone or backend ffmpeg to convert that raw buffer to WAV ?

    Thank so much.
