• Unwrapping Matomo 5.2.0 – Bringing you enhanced security and performance

  25 décembre 2024, par Daniel Crough — Latest Releases

   As we tie a bow on 2024, we’re delighted to share our final gift of the year. Matomo 5.2.0 comes wrapped with new security features, privacy controls, and performance improvements to enhance your analytics experience.

   Enhanced security and privacy controls

  

  We’ve strengthened Matomo’s security framework with several key updates :

  • A new installer timestamp mechanism for on-premise installations creates a secure 72-hour installation window, preventing unauthorised access during setup
  • Enhanced account security features including a “This Wasn’t Me” link in password reset emails and location-based login alerts
  • The new Global List of Query URL parameters feature lets you refine tracking by excluding sensitive or unnecessary parameters from collection

  Tag manager improvements for better efficiency

  

  The Matomo Tag Manager now includes several features to streamline your workflow :

  • New Consent Management Platform (CMP) tags for CookieYes, OneTrust, and Axeptio, simplifying consent tracking implementatio.
  • A new copy feature for containers, tags, and triggers that reduces setup time and ensures consistency across multiple properties
  • Improved management tools for maintaining standardised tracking across websites

  Performance and reliability updates

  We’ve made technical improvements to enhance Matomo’s performance :

  • Full PHP 8.4 compatibility for improved performance and reliability
  • Optimised archiving processes including smarter handling of recent data
  • New recovery options for interrupted archiving processes
  • Specific improvements for TiDB compatibility, enhancing database performance for users of this engine

  Important to note : This release does not require any major database upgrade, making it easier to implement these improvements.

  Looking forward to 2025

  As we prepare to enter a new year, these updates reflect our ongoing commitment to providing privacy-focused analytics. We’re grateful to all our community contributors who have helped make this release possible. Special thanks to the Matomo community for their contributions to this release.

  Ready to explore these new features ? Update to Matomo 5.2.0 today and start the new year with enhanced security, efficiency, and control over your analytics data.

  From all of us at Matomo, thank you for being part of our journey. Here’s to another year of protecting privacy and empowering insights together !

• mpegts muxer, DVB subtitles encoder : common DVB subtitles payload

  11 janvier 2014, par Serhii Marchuk

  mpegts muxer, DVB subtitles encoder : common DVB subtitles payload
  Improved DVB subtitles encoder to generate AVPacket.data in the same
  
  format as generates MPEGTS demuxer + DVB subtitles parser. So now single
  
  format of DVB subtitles data is used across all the components of FFmpeg :
  
  only subtitles payload WITHOUT 0x20 0x00 bytes at the beginning and 0xFF
  
  trailing byte.
  Improved MPEGTS muxer to support format of DVB subtitles in
  
  AVPacket.data described above : while muxing we add two bytes 0x20 0x00 to
  
  the beginning of and 0xFF to the end of DVB subtitles payload.
  The patch fixes DVB subtitle copy problems : tickets #2989 fully and #2024
  
  partly.

• Ffmpeg input seeking - "Invalid NAL unit size"

  30 janvier 2024, par Dimitris

  I'm trying to use ffmpeg to get a 10-second clip from the middle of a video. The execution time of the command is important, that's why I've decided to use combined input & output seeking (as illustrated here).
The input video file is a CMAF with fragmented MP4, duration of 10 minutes.

  


  I'm testing on a Mac, Ffmpeg version is 6.1.1.

  


  This is the command that I'm using :

  


  ffmpeg -nostdin -y -ss 290 -copyts -start_at_zero -i https://devcdn.flowplayer.com/5f07362e-c358-41d0-857a-c64302a3fcc9/cmaf/17bdb16d-71d1-414c-a291-a028bd45b9ec/playlist_360.m3u8 -ss 300.0 -t 10 -vcodec libwebp -lossless 0 -quality 60 -compression_level 2 -loop 0 -an -sn output.webp


  


  Result : no output file is created.

  


  From what I understand it fails to seek position "290" in the video, probably due to "Invalid NAL unit size" errors.

  


  Here's the output :

  What I've tried so far :

  


  


  1. Downloaded the input file to a local directory and used it as input to ffmpeg - same results.

     


  


  2. Used the mp4 file from the playlist directly as an input to ffmpeg - worked but execution time is very slow

     


  


  3. Emmited the input seeking part (-ss 290 -copyts -start_at_zero) from the command - worked but also very slow in terms of execution time

     


  


  


  Any ideas on why I'm getting "Invalid NAL unit size" and how to make the command work with input seeking ?
