Ajouter notes et légendes aux images
7 février 2011, parPour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

Error in making animation through ffmpeg (python3.9)
20 avril 2024, par Taehyung GhimWhen I try to make 2D animation map for cow tracking(matching 2 camera views) through ffmpeg, following error occurs.



raise subprocess.CalledProcessError(subprocess.CalledProcessError: Command '['ffmpeg', '-f', 'rawvideo', '-vcodec', 'rawvideo', '-s', '4000x4000', '-pix_fmt', 'rgba', '-r', '5', '-loglevel', 'error', '-i', 'pipe:', '-vcodec', 'h264', '-pix_fmt', 'yuv420p', '-metadata', 'artist=Me', '-y', '../out_detect/run7/TRACKS_ANIMATION_fused.mp4']' returned non-zero exit status 1.

I am confident it has nothing to do with the animation data, the error occurs even when I create a simple test animation :


import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation
# plt.rcParams['animation.ffmpeg_path'] = '/usr/bin/ffmpeg'

fig = plt.figure()
ax = plt.axes(xlim=(0, 2), ylim=(-2, 2))
line, = ax.plot([], [], lw=2)


def init():
 line.set_data([], [])
 return line,


def animate(i):
 x = np.linspace(0, 2, 1000)
 y = np.sin(2 * np.pi * (x - 0.01 * i))
 line.set_data(x, y)
 return line,


anim = animation.FuncAnimation(fig, animate, init_func=init,
 frames=200, interval=20, blit=True)

FFwriter = animation.FFMpegWriter()
anim.save('basic_animation.mp4', writer=FFwriter)


I am currently using PyCharm in LinuxMint and I have a fairly new version of FFMpeg (4.2.4) installed. Given that FFMpeg complains about 'rawvideo' which as far as I understand it is just a bunch of images in series, it seems unlikely this has anything to do with codecs. If I run ffmpeg -formats, sure enough rawvideo is in the list.


I have tried manually setting plt.rcParams, like in the commented line in the code above, with no success. I have also tried setting up both anaconda and venv environments, but I get the same error.
Annoyingly, I did not have this problem a few months ago when I was using Ubuntu. I have also verified that it works on my friends Ubuntu desktop, using the same simple venv as I set up for myself.


Any ideas ?


EDIT : I use the fish shell, if that is relevant...


Well this is peculiar. If I start a terminal from within PyCharm and check supported formats, I get the following :

As is evident, there is no support for 'rawvideo' in the list above ! Very strange indeed, I do not know which ffmpeg this list belongs to, perhaps it is a version integrated into matplotlib's animation class ?


Anyway, if I uncomment the line setting the ffmpeg_path I am back at the old error. I did get it to work however, by changing the path from '/usr/bin/ffmpeg' to '/home/j/.conda/envs/venvtest/bin/ffmpeg'. Then I get the file to run, create the animation and save it. This works for my real files as well, which do not even run that particular conda-environment. They do not recognize or find the ffmpeg I have in /usr/bin though. I have no clue why but at least I have a workaround now.


Final edit :
It is solved. It was flatpak's fault. Lesson is, don't use flatpak (or snap for that matter) to install Pycharm.

Tv box failed to open encoded videos using x265 HEVC encoder
3 juin 2022, par Constadinos ChatzisI have Zidoo X9S tv box and it has support for x265 HEVC codec. Every single video i throw in it, HDR 4K or standard x264 videos, it plays perfectly except my encoded x265 video when i select it to play, it freezes and it doesn't load. I believe it has something to do with my encoding settings. The encoding command i use with ffmpeg, is this :


-c:v libx265 -crf 10 -preset veryfast output.mkv


Any ideas why this is happening ?
