New proposed ePrivacy Regulation and why Piwik might not need tracking consent compared to Google Analytics & co
11 janvier 2017, par InnoCraft — CommunityThe EU is proposing new ePrivacy Regulations. The proposed Regulation on Privacy and Electronic Communications will increase the protection of people’s private life and open up new opportunities for business.
The new ePrivacy Regulation proposal
The proposal mentions several changes for example to the “Cookie Law” where no longer a cookie consent will be needed when the cookies improve the user’s internet experience, for example to remember the shopping cart history or when completing a form over several pages.
However, consent to track a user’s behaviour may be needed in the future, unless the analytics data collection is hosted on the first-party website.
From TheRegister : O’Neil noted a minor change in which visitors to a website for analytics purposes do not require consent, as long as any personal data collected is only processed by the first party.
First party Analytics respecting privacy
Piwik is an open-source analytics platform that is used on more than 1 million websites and apps in over 150 countries, and available in more than 50 languages. The difference with other analytics solutions is that you can download and install Piwik on your own infrastructure. Websites and mobile apps tracking users with their own Piwik very likely won’t require a consent from their users if these regulations become reality.
We have regularly written about why privacy matters, or more recently 11 ways Piwik Analytics helps you to protect your visitors privacy.
Besides the standard Piwik features, there are Premium Features that let businesses and organizations further maximize their success based on the tracked data. Need help in hosting Piwik on premise ? InnoCraft are THE Piwik experts and know it best as it is the company of the makers of Piwik. InnoCraft provides support subscriptions and enterprise packages to help you setting up, configuring and maintaining Piwik on your infrastructure as well as offer training and custom development.
We’re excited to be building the best digital analytics platform which respects our privacy on the Internet.
Thank you for being a valued member of the Piwik community !

Does ffmpeg rtp_mpegts muxer support setting DVB triplet ?
19 février 2021, par drake7It seems ffmpeg lets you set the DVB triplet with UDP but not with RTP.


FYI : This is a followup on my findings about the
rtp_mpegts
muxer compared to thempegts
muxer : Question

In my tests I was using
ffmpeg version 4.3.1-2021-01-01-full_build-www.gyan.dev
on windows.

findings


I analyzed my streams with
dectec
's "StreamXpert" :

- 

-
With UDP and it's
mpegts
muxer, the DVB triplet can be set (1)

-
With RTP and it's
rtp_mpegts
muxer, the DVB triplet is ignored (3) (Note that 3a and 3b create very similar results in "StreamXpert".)

-
Using UDP with DVB triplet as input and output with RTP ignores the DVB triplet (2)











Interestingly, leaving out the following options...


-pcr_period 20 -pat_period 0.10 -sdt_period 0.25 -metadata:s:a:0 language=nya \
-mpegts_flags +pat_pmt_at_frames -mpegts_flags system_b



... the
rtp_mpegts
muxer (3b) creates a valid DVB transport stream, while the thempegts
muxer (4) does not.

Revision 393a8ccef9 : Remove avoid_frame_with_high_error from RD loop The feature undergoes prior ass
6 janvier 2014, par Jingning HanChanged Paths :
Modify /vp9/encoder/vp9_block.h
Modify /vp9/encoder/vp9_onyx_if.c
Modify /vp9/encoder/vp9_onyx_int.h
Modify /vp9/encoder/vp9_rdopt.c
Remove avoid_frame_with_high_error from RD loopThe feature undergoes prior assumption that the recursive partition
size search from 4x4 to 64x64, hence utilizing information from small
blocks to determine early termination in large block rate-distortion
optimization search. The current codebase is now going from top down.
The previous function might go with not properly initialized values,
hence removed.Tested on pedestrian_area_1080p at 4000 kbps running under speed 2.
No visible difference in runtime observed.Change-Id : I553df415c6191413762db7ae34e8790c71d8118e
