• ffmpeg : adding a stream non-muxed stream with correct codec type tagging

  13 janvier 2021, par Hamish

  In common use, I believe ffmpeg requires inputs to be in a specified muxer format which contains one or more data streams which can be decoded with a codec supported by the demuxer associated with the format. I have a data stream (not audio or video) which is already encoded with a codec but is not muxed. How can I get this stream into the ffmpeg pipeline with the correct codec type assigned so that the muxer knows what to do with it ?

  


  I have tried streaming the data over UDP and specifying the data demuxer. With some combinations I get get it to say it's streaming, I can never get a player to connect, presumable because the output of mpegts is either null or invalid. Command line :

  


  ffmpeg -v verbose ^
-f flv -listen 1 -i rtmp://127.0.0.1:1101 ^
-f data -i udp://127.0.0.1:1300 ^
    -map 0:v -vcodec mpeg2video -map 1:d -f mpegts -mpegts_m2ts_mode 1  udp://localhost:1200


  


  Result (partial) :

  


  Input #0, flv, from 'rtmp://127.0.0.1:1101':

  The codec type name is klv, which has the tag KLVA. It is only supported by the mpegts and mxf (de)muxers. I presume there must be a way of getting into the pipeline without having a valid mpegts or mxf stream in the first place otherwise we have a kind of paradox.

  


  I've tried specifying the codec on the input, but it fails validation, I guess because the data demuxer does not support it.

  


  Somehow mp4 files can be muxed from elemental streams (h264 and aac files), but I guess there must be some special case in the code to force the codec type based on the file extension.

  


  I would really love to do this from the command line with a public build but if this is absolutely not possible, I would also welcome some advice about it could be achieved from C++ code.

• Piwik is now Matomo – Announcement

  
  9 janvier 2018, par Matomo Core Team

  You may be surprised to read this announcement, but no stress, take a deep breath, nothing big is going to happen, it is just our name that is changing and here are the reasons why.

  

  Why are we changing from Piwik to Matomo ?

  “After an epic 10 year journey creating and perfecting the best open digital analytics solution, we felt it was a good time to refresh our brand to reflect how far we have come and to reaffirm our vision :
  To create, as a community, the leading international open source digital analytics platform, that gives every user full control of their data.”

  Matthieu Aubry, creator of Piwik

  As projects evolve, so do names. After 10 years of Piwik and the amazing achievement of building the top open source analytics software that gives every user full control of their data, we are now looking forward to the next chapter. Thus, Piwik, the community project, will now become Matomo. The only change is our name, everything else stays the same.

  This will allow users to take a fresh look at what we’ve become today and acknowledging all of the community’s hard work over the past 10 years. In addition, we also want our name to be unique, ensuring that it is not shared with any other company to remove any possible confusion or affiliations. Piwik is already used on over 1 million websites and with Matomo, we hope to reach our maximum potential.

  With the strong focus on privacy worldwide and the upcoming privacy regulations about to be legislated in Europe, it is clear that we were on the right mission from the very beginning. With the upcoming big release Matomo 4.0 planned for this year, new privacy protections will bring users the tools to be compliant with the GDPR privacy laws. And Matomo will grow in line with these regulations, with a very clear and focused vision.

  Changing our name is an exciting opportunity for us, and we hope you love the name Matomo as much as we do.

  Matomo FAQs

  So what is going to change for me ?

  Well, basically nothing, the name will change but the values stay the same : Matomo (Piwik) will continue to be free and always will be.

  Also the same people stay behind the project. We are motivated more than ever to take this project to the next level.

  Why not keep the name Piwik ?

  For a few reasons, one of which is to ensure that Matomo does not/will not share its name with any other businesses unlike Piwik. We also want to protect the Matomo brand and for it to remain the open source community project name forever.

  Where does the name Matomo come from ?

  We loved the name Piwik and were looking for something that sounded just as good ! Initially we wanted to have an acronym based on key terms, such as Free, Open Source and Privacy, but none really fit us perfectly.

  Until we found Matomo ! Easily pronounced in all languages. Short enough to remember. Concise. And best of all… Matomo means honesty in Japanese. Which aligns with one of our key values – transparency.

  We love the name Matomo and hope you do too.

  What is the vision of Matomo ?

  

  We have come a long way in those 10 years ! However, our mission statement remains the same :

  “To create, as a community, the leading international open source digital analytics platform, that gives every user full control of their data.”

  Matomo provides a range of amazing and innovative features, allowing you to get a 360 view of your visitors. These insights are invaluable to help understand behavior, keep track of goals, and increase conversion rates and revenue.

  Who will deliver Matomo professional services ?

  Any company who wishes to. The only exception is that no companies will be allowed to have the name Matomo.

  Our company providing professional services is and will remain InnoCraft.

  Where can I follow the Matomo project ?

  Our new website will be matomo.org (automatically redirected from Piwik.org)

  Follow our new Twitter : twitter.com/matomo_org

  Github : github.com/matomo-org

  Facebook : facebook.com/Matomo.org

  Linkedin : linkedin.com/company/matomo/

  Where can I see a demo of Matomo ?

  On demo.matomo.org

  Where can I download Matomo first release ?

  What is the new logo ?

  Matomo trademark Policy

  Matomo is an internationally registered trademark of Matthieu Aubry, Founder of Piwik (now Matomo).

  Information about how to use the name Matomo (and logo) can be found here : matomo.org/trademark/

  What are the next big steps ?

  We will keep it simple for our valued users. As it is just a name change, the only thing you will notice is that the Piwik brand will gradually be replaced on the websites you are used to seeing the name on. The first version of Matomo will be available in just a few days for download. The software version numbers stay the same : the next release after Piwik 3.2.1 will be Matomo 3.3.0.

  All our public HTTP APIs and Tracking SDKs will continue working normally. As you can imagine, there is a lot of work and complexity behind slowly updating all the SDKs and keeping backwards compatibility, so our renaming project will take a few weeks to complete.

  The Matomo trademark will later be transferred into the Matomo foundation, a non-profit that will be dedicated to promoting and ensuring access to Matomo and our related open source projects in perpetuity.
