Possibilité de déploiement en ferme
12 avril 2011, parMediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...) -

Tweaking FFMPEG Stream For Games For Open Source Projech
12 novembre 2022, par Devin DixonRight now I am using FFMPEG to record and broadcast video games on a open source projected call Glitch : https://www.glitch.fun/


The problem is the streams are a little but choppy and pixelated. Here is an example video recording :




The FFMPEG command I am currently for getting the stream from a source and sending it to a recording file and to destinations is as follows :


ffmpeg [some_input_source] -vf scale=1920x1080 -pix_fmt yuv420p -r 60 -b:v 4000k -maxrate 4000k -bufsize 4500k -vcodec libx264 -preset veryfast -keyint_min 24 -level 3.0 -s 1920:h=1080 -g 40 -x264opts no-scenecut -strict experimental -f [output_location]


What can I tweak in here to improve the quality of streaming for games ?

FFMPEG : Multicast packets incoming, but input stream does not open
2 septembre 2022, par oldslowI have a weird problem with ffmpeg and I was wondering if someone might know what's going on.


We have transcoding clusters outputting video to a multicast network. In some computers of the same network, I'm able to open these streams with a command like :


ffplay -i "udp://239.{mutlticast address}:10001?localaddr={Local adapter IP which receives packets}" -nodisp -loglevel trace

But in other computers it does not work. Particularly in a server running Centos 7 I just get :


[NULL @ 0x7fc9a4000920] Opening 'udp://239.xxx.xxx.xxx:10001?localaddr=xxx.xxx.xxx.xxx' for reading
[udp @ 0x7fc9a40012a0] No default whitelist set 
[udp @ 0x7fc9a40012a0] end receive buffer size reported is 131072
nan : 0.000 fd= 0 aq= 0KB vq= 0KB sq= 0B f=0/0


I was thinking it might be a network problem. I started Wireshark to see if the packets were coming in and the thing is, they are ! As soon as I start FFMpeg/FFplay, the MPEG TS packets start coming in, but still FFMpeg won't open the stream :

Anyone have any idea what can I do to fix this ?
Thanks a lot !

Open Video Downloader Error : Postprocessing : ffmpeg not found
11 septembre 2022, par Nick the Community ScientistError Thrown :


ERROR: Postprocessing: ffmpeg not found. Please install or provide the path using --ffmpeg-location


Context : macOS Big Sur M1 Chip, using the open video downloader program GitHub release or Homebrew. This specifically was thrown at the end of downloading the video file and the audio file from a given URL. The two files remained separate as a result of the error, the video was playable normally, but audio was in a .webm format (unusable for most people).


Analysis : It is clear that a dependency is missing, or its path cannot be located. For macOS users like me, the first step after checking the app's preferences for a path set or dependency download function is to check for the given dependency in the system. Once checking using Homebrew, it became clear that several dependencies were missing.
