Installation en mode ferme
4 février 2011, parLe 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 (...)

ffmpeg codec error on audio file
31 juillet 2013, par foosionI have some m4a files that will not play properly using the google music player app on my Android phone, although they play fine on most everything else. I thought the problem was the container and thought "ffmpeg -i bad.m4a -codec copy good.m4a" might help. However, when I run on the problem files, I get error messages. Running this command on non-problem files has not generated error messages.
Please suggest ways to fix (other than re-encoding).
[D:\temp\dl]ffmpeg -i "01 - The Day Begins.m4a" -codec copy day.m4a

Convert HEVC video to a more widely supported format using fluent-ffmpeg in Node.js
21 juin 2021, par Daniel LoitertonMy app allows users to upload videos from their phones. However, the latest iPhone default format (HEVC / H.265) does not seem to be supported by Chrome and other browsers, so some users cannot stream the videos.


I'm already using fluent-ffmpeg on my Node.js backend to read metadata and extract thumbnails from the uploaded videos. How would I go about converting HEVC videos to something else ? What format/options would be appropriate for streaming to browsers ? Ideally I'd like to keep files fairly small, and I'm willing to sacrifice some quality to that end.

What can be the substitute for SDL to direct ffmpeg decoded videos to screen in IOS ?
18 octobre 2012, par jAckOdEI making a iOS video player using ffmpeg, the flow likes this :
Video File---> [FFMPEG Decoder] —> decoded frames —> [a media director] —> /iphone screen (full and partial)/
A media director will handle the tasks of rendering decoded video frames to iOS ui (UIView, UIWindow etc), outputting audio samples to iOS speaker, and threads management.
SDL is one of those libs, but SDL is mainly made for game making purpose and seem to be not really mature for iOS.
