• Manually Adding h265 codec support to FFMPEG v1.0.10

  11 mars 2018, par Joe90210

  I have looked everywhere and I can’t seem to find a solution. I am using Debian 7 wheezy, I have managed to get as far as having the following version installed.

  ffmpeg version 1.0.10 Copyright (c) 2000-2014 the FFmpeg developers
  
  
  
  built on Jul 25 2014 07:50:40 with gcc 4.7 (Debian 4.7.2-5)

  But as you will see below there is no H265 support which is making for a real headache trying to convert iOS MOV files to MP4. Has anybody had any luck with this ordeal ? I’ve looked through stackoverflow for 3 hours and see nothing even close here.

   ffmpeg -codecs | grep h26
  
   DEV.L. h261                 H.261
  
   DEV.L. h263                 H.263 / H.263-1996, H.263+ / H.263-1998 / H.263 
  
   version 2
  
   D.V.L. h263i                Intel H.263
  
   DEV.L. h263p                H.263+ / H.263-1998 / H.263 version 2
  
   DEV.LS h264                 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: h264 h264_crystalhd h264_vdpau ) (encoders: libx264 libx264rgb )

  Using a different software version at this time is not an option, I am aware of how lacking the packages can be with Debian.

  Thank you

• Why Opencv image comparisson doesn't work ?

  6 mai 2018, par yash17

  We are using the following method for image comparison.

  1.Image is captured using ffmpeg,of udp streaming on vlc.

  2.A portion of an image is cropped,using y:y+h::x:x+w co-ordinates of the image.

  3.The cropped image is compared with a reference image using opencv2

  Previously we used to get image comparison results perfectly for these method and code,whereas from last couple of executions,the same code is not giving us proper results on extraction.It gives us same image result for even different images.

  from PIL import Image
  
  import cv2
  
  import os
  
  import sys
  
  import numpy as np
  
  import time
  
  import subprocess
  
  from Keycode import send
  
  p = subprocess.Popen("ffmpeg -y -i udp://@xxx.xx.xx.xx:xxxx -vframes 1     -q:v 1 sign.png",shell=True)
  
  output = p.communicate()[0]
  
  
  
  image1=cv2.imread('sign.png')
  
  crop1= image1[451:491, 496:531]
  
  i1 = cv2.imwrite('crop1.png',crop1)
  
  i2 =cv2.imread('sign_ref.png')
  
  difference = cv2.subtract(i1, i2)
  
  result = not np.any(difference)

• Matomo SSO options and why is it useful ?

  8 novembre 2017, par Matomo Core Team — Plugins

  Bored with typing again and again different logins and passwords for each service you have access to ? Would you like to add hundreds or thousands of users with different roles to your Matomo (Piwik) at once ? Would you like to save time and effort of managing your users while increasing the security in your business ? Guess what, Matomo has come up with great features to do just that.

  But what is a SSO ?

  Before introducing you to new Matomo (Piwik) features, let me explain what a SSO is.
  SSO is the acronym for Single Sign On. As its name suggests this authentication process allows a user to access multiple applications with one set of login credentials.

  Advantages of using a SSO are numerous :

  • improving security, for example when an employee is leaving your company, how can you check that all his credentials have been removed ?
  • reducing employees time-wasters such as having to enter logins/passwords each time.
  • providing a centralized database for administrators. They can then easily manage permissions of all employees saving them heaps of time.
  • reduces support costs related to authentication / accounts management.

  In order to provide SSO options, two Matomo (Piwik) plugins have been developed and are available on the marketplace :

  • SAML
  • LDAP

  SAML

  

  SAML stands for “Security Assertion Markup Language”, it is a standard in order to exchange authentication and authorization between an identity provider (OneLogin, Okta, Ping Identity, ADFS, Google, Salesforce, SharePoint…) and a service provider.
  An identity provider is an online service that authenticates users on the Internet by using security tokens.

  Are you wondering if your business or organization is using any of these providers ? We recommend to ask your operations team or sysadmin.

  At InnoCraft, we developed a plugin in order to allow SSO with SAML for Matomo (Piwik). It can ensure consistent access control across the enterprise and external providers, potentially reducing support costs related to authentication and accounts management.

  The installation process is straightforward. All you need is to get the SAML premium feature from the marketplace. Once installed, you will access the SAML configuration interface through the admin where you can configure various settings :

  • SAML Status
  • Identity Provider (Entity ID, SSO endpoint info, Public x509 certificate)
  • Just-in-time provisioning and Mapping attributes
  • Access Synchronization
  • Advanced settings

  

  From there you will need to follow our detailed documentation to have it up and running :
  https://matomo.org/docs/login-saml/.
  Once finished, you will then be able to use SAML to authenticate to your Matomo (Piwik) account :

  

  As all premium features, SAML is eligible to a 30-day period money back guarantee, so do not hesitate to have it a try.

  LDAP

  

  LDAP stands for Lightweight Directory Access Protocol. As its names implies LDAP is a directory, hosted on a server, which organizes the data about people in your company.
  Thanks to the LDAP plugin, Matomo (Piwik) can be connected to your LDAP infrastructure and then use all its power in order to give each individual an access with different rights according to their needs.

  Let’s say that you have 1,000 employees within a company and they all need right now an access to the analytics reports in Matomo (Piwik) with different roles. This is what LDAP can do.

  Moreover if your business or organization is already using LDAP, we recommend using the LDAP connector for Matomo (Piwik) for better security, to stop wasting time of your users and sysadmins, and to reduce the costs related to account management.

  You understood it well. LDAP is a plugin which saves a LOT of time within an organization. Here is a preview of the settings part :

  

  LDAP has been developed by the Matomo (Piwik) core team and is available as a Free plugin on the marketplace.

  If you are surprised by the possibilities that Matomo (Piwik) is offering in terms of plugins, the good news is that many other plugins are waiting for you on the marketplace. Check out our premium marketplace which offers state-of-the-art plugins to get the most out of Matomo.

  And if you are a developer feel free to create your own plugin, a detailed documentation is available at : https://developer.matomo.org/guides/getting-started-part-1.
