Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

But when the chart produced, it shows no line. What did I do wrong ?



Thank you.

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')
