  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • How to transcode .mp4 files using ffmpeg celery rabbitMq in Amazon Linux ?

    11 mars 2017, par Srinivas 25

    I want to transcode .mp4, .flv files by using ffmpeg, celery and rabbitMQ. With the help of these tools i can able to transcode in localhost, where in
    my OS is ubuntu, but i am unable to do the same on AWS Linux for production
    Here is the code i am using to integrate ffmpeg, rabbitMQ and celery to transcode on Amazon Linux

    FFMPEG_PATH = '/usr/bin/ffmpeg'
    

    

    
CELERY_BROKER_URL = 'amqp://guest:guest@awsuser:5672//'
    
CELERY_ACCEPT_CONTENT = 'file'
    
CELERY_RESULT_BACKEND = 'rpc://'
    
CELERY_TASK_SERIALIZER = 'file'

    celery.py

    from __future__ import absolute_import
    
import os
    
from celery import Celery
    
from afnity.settings import CELERY_BROKER_URL
    

    
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'afnity.settings')
    

    

    
app = Celery('taskapp',
    
         broker=CELERY_BROKER_URL,
    
         include=['taskapp.tasks'])
    

    
app.config_from_object('django.conf:settings', namespace='CELERY')
    

    

    
if __name__ == '__main__':
    
app.start()

  • Opening Video with opencv3 and python on Amazon EC2

    11 octobre 2016, par stml

    I successfully set up python and opencv3 on an t2.micro instance by following these instructions : http://stackoverflow.com/a/38867965/1213715

    The script which worked on my local machine no longer works. The problem seems to be with importing video. The start of my code now looks like this :

    import numpy as np
    
import cv2
    

    
cap = cv2.VideoCapture('/home/ec2-user/test.mov')
    

    
if(cap.isOpened() == False):
    
    print "Can't open video"
    
    exit()

    This exits every time. I have tried different paths and different video formats (including .avi).

    In other threads, I read that ffmpeg is essential to cv2 video functions, and successfully installed this using the instructions at https://forums.aws.amazon.com/thread.jspa?messageID=524523. I can now run ffmpeg from the command line - but it has not changed the cv2 output.

    Do I need to link ffmpeg to cv2 somehow, or do I need to recompile entirely - and if so, what change should I make to the original installation instructions ?

    Python version 2.7.12

    Opencv version 3.1.0

  • Install gstreamer on EC2 Amazon Linux AMI ?

    6 décembre 2015, par vy32

    I’m trying to install QT5.5 on Amazon EC2 Linux, which apparently requires that I install some kind of multimedia support. It looks like that comes from gstreamer.

    yum search gstreamer turns up :

 You could try using --skip-broken to work around the problem
    
 You could try running: rpm -Va --nofiles --nodigest
    
[ec2-user@ip-172-30-1-58 ~]$

    Supplying the suggested --skip-broken doesn’t help :

    [ec2-user@ip-172-30-1-58 ~]$ sudo yum install -y gstreamer-ffmpeg --skip-broken

    gstreamer-ffmpeg-0.10.13-15.el7.nux.x86_64 from nux-dextop
    
[ec2-user@ip-172-30-1-58 ~]$

    So how do I install gstreamer-ffmpeg ? Why aren’t the dependencies automatically being followed ?
