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.

Python FFmpeg : Setting VBR and BT.709
14 décembre 2019, par CryptonautI’m using this Python library to programmatically generate a short video using an image (.png) as input. The video needs to match the specifications of another video created by someone else.
The key differences between my output and the other are the following (these are the media attributes I desire to have) :
- BitRate_Mode : VBR
colour_primaries : BT.709(Solved via the comment made by Rotem - updated my code example to include the solution)
How would I achieve VBR ? It was my understanding ProRes 422 HQ natively used unconstrained VBR yet my output specifies CBR.
Secondly, as can be seen from my code, I’m attempting to conform to BT.709. However, my media information output does not specify this. What am I doing incorrectly ?Here’s my code :
image = ffmpeg.input(input_image, t='00:00:10', framerate='24000/1001', loop='1', probesize='42M')
output = ffmpeg.output(image, output_video,
f='mov',
vcodec='prores_ks',
vprofile='3',
pix_fmt='yuv422p10le',
g='48',
video_track_timescale='24000',
movflags='use_metadata_tags',
timecode='00:00:00:00',
color_primaries='bt709',
color_trc='bt709',
colorspace='bt709',
qcomp='1',
# BT.709 issue solved by adding the bsf option as seen via the line below
bsf='prores_metadata=color_primaries=bt709:color_trc=bt709:colorspace=bt709',
vf='scale=in_range=full:in_color_matrix=bt709:out_range=full:out_color_matrix=bt709')
