Today we celebrate Data Privacy Day 2019
28 janvier 2019, par Jake Thornton — PrivacyToday we celebrate Data Privacy Day 2019 !!!
What is Data Privacy Day ?
Wikipedia tells us that : The purpose of Data Privacy Day is to raise awareness and promote privacy and data protection best practices.
Our personal data is our online identity. When you think what personal data means – our phone records, credit card transactions, GPS position, IP addresses, browsing history and so much more. All so valuable and personal to us as human beings.
That’s why we cannot take our personal data online for granted. We have a right to know which websites collect our data and how it’s then used, something that’s often not visible or easily recognisable when browsing.
What Data Privacy Day means to Matomo
Every year the team at Matomo uses this day as a chance to reflect on how far the Matomo (formerly Piwik) project has come. But then also reflect how far we still have to go in spreading the message that our data and personal information online matters.
2018 saw the introduction of the EU General Data Protection Regulation (GDPR) to protect people’s data online. As a team, Matomo was at the forefront of this development in the analytics space and have since built a GDPR Manager to ensure our users can be fully compliant with the GDPR.
With every new release of Matomo, we are ensuring that security continues to be at the highest standard and we will continue to be committed to our bug bounty program. Our most recent release of Matomo 3.8.0 alone added a Two Factor Authentication (2FA) feature and a password brute force prevention.
What next for Matomo and data privacy ?
As always, security is a top priority for every new release of Matomo and continues to only get better and better. We have a duty to spread our message further that the protection of personal data matters and today is a vital reminder of that. We are, and forever will be, the #1 open-source (and free to use) web analytics platform in the world that fully respects user privacy and gives our users 100% data ownership.
In 2018 we changed our name, we updated our logo and website, and advanced our platform to compete with the most powerful web analytics tools in the world, all so we can spread our message further and continue our mission.
Come with us on this exciting journey. Now is the time to take back control of your data and let’s continue creating a safer web for everyone.
Please help us spread this message.

I tried the following commands,



ffmpeg -i input.mp4 -map_metadata -1 -c copy output.mp4



ffmpeg -i input.mp4 -metadata original_display_aspect_ratio=0 -c copy output.mp4



but none of them worked.



If I want to remove the "original display aspect ratio" entry completely, what ffmpeg command can I use to achieve that ?



Thank you.

Using ffmpeg to overlay dvdsub
27 avril 2019, par ib11I am trying to overlay a dvdsub file pair (*.idx + *.sub) to a video file.
This is the batch script with the command line I am trying to use :
@echo off
set srcVidFile1="myvideo.mov"
set srcSubFile=mysub.sub
set srcIdxFile=mysub.idx
set destFile=D:\testsub.mp4
ffmpeg.exe -i %srcVidFile1% -i %srcSubFile% -i %srcIdxFile%
-filter_complex "[0:v][1:s]overlay" -c:s dvdsub -c:v
libx264 -crf 24 -c:a aac -b:a 160K -ar 48K -strict -2 -y
%destFile%This however only accepts 720x576 VOBsub files. And also the color gets inverted.
My video however is 1080p and do have a 1920x1080 VOBsub file pair, but when I trying use them, I get an error sub2video : rectange (xxx xxx xxx xxx) overflowing 720 576
