Configuration spécifique d’Apache
4 février 2011, parModules spécifiques
Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

15 janvier 2021, par lavAzzaI try to make video from 2 jpeg (6912x3456 px, files is large it is 360 panoramas) with ffmpeg by


ffmpeg -r 1/4 -pattern_type glob -i "my_dir/*.jpg" -c:v libx264 -profile:v high -crf 18 -vf "fps=30,format=yuv420p" -movflags +faststart output.mp4


And ffmpeg process hang. I get

nginx RTMP to HLS : FFMPG error when trying multiple bitrate output [on hold]
28 mai 2014, par user3685074I’m currently trying to convert my RTMP Livestream into a HLS with 3 quality-settings.
I followed this guide
I’ve compiled my own FFMPEG and it’s working if I just convert 1 file.
It seems libx264 isn’t able to do multiple encodings at the same time ?I’m using these command :
