Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

ffmpeg : "Error setting profile" ; how to keep original resolution odf odd sized videos ; getting Quicktime compatible output ; fixing pixel format
26 février 2017, par P. ReidI’ve been having trouble using ffmpeg to compress videos to something readable by quicktime. My goal in the end is to have a simple command that I can use to compress high bitrate videos (ie screencaptures) to something more reasonable to be able to share them with people.
I want to use a command I found here as a starting point :
ffmpeg -i input-file.avi -codec:v libx264 -profile: high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=-1:480 -threads 0 -codec:a libfdk_aac -b:a 128k output_file.mp4
Unfortunately I get this error :
[libx264 @ 0x7f92ab81c200] Error setting profile high.
[libx264 @ 0x7f92ab81c200] Possible profiles: baseline main high high10 high422 high444
Stream mapping:
Stream #0:0 -> #0:0 (rawvideo (native) -> h264 (libx264))
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or heightIf I take out the
-profile: high
the command functions but the output still doesn’t open in quicktime (it does in VLC). I can’t find the keyword-profile
on the ffmpeg man page : https://ffmpeg.org/ffmpeg.html so I don’t know if this is important or what to do about it.Does anyone know what might be causing my problem ? What should I do to try and debug this problem ? I would describe myself as inexperienced so sorry if I’m missing something obvious.
Thanks in advance for your help,
PeterThis is my ffmpeg version :
