Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

How to find currently streaming file in ffmpeg stream that uses a file list
27 février 2021, par DigitalDisasterI am using ffmpeg to stream to an RTMP server. I am using the option to provide ffmpeg a text file with a list of files to stream. My file looks like this :


ffconcat version 1.0
file 'stream_file1.flv'
file 'stream_file2.flv'
file 'stream_file3.flv'



It loops through these files while streaming. Is there a way to programmatically find out when ffmpeg switches between each file ? Either from ffmpeg dumping some logs that I can injest, or by using python to check the state of the stream every second ?
