• TCP Connection refused error when using FFMPEG for audio stream to HTTP on macOS

  26 novembre 2020, par freddy

  I'm trying to stream my microphone input via HTTP using ffmpeg, so I can stream it in HTML. I run the following ffmpeg command :

  


  ffmpeg -f avfoundation -i ":1" -c:a libmp3lame -f mp3 -r 30 http://localhost:809

  


  It, however, crashes with the following error message :

  I've had success with streaming on that port using VLC, but it for some reason won't work using ffmpeg. Any ideas on how to fix this ?

  


• avfilter/vidstab : add option for file format specification

  22 octobre 2023, par Gyan Doshi

  avfilter/vidstab : add option for file format specification
  The vidstab library added support in Nov 2020 for writing/reading
  
  the transforms data in binary in addition to ASCII. The library default
  
  was changed to binary format but no changes were made to the AVfilters
  
  resulting in data file for writing or reading being always opened as text.
  
  This effectively broke the filters.
  Option added to vidstabdetect to specify file format and open files in
  
  both filters with the correct attributes.

• Introducing Improvements to the Opt-Out Form Feature

  18 septembre 2022, par Ben — About

  Matomo includes a built-in opt-out form that you can add to your website so you can provide your visitors with the choice to opt-out of Matomo tracking. Up until Matomo 4.12.0 the built-in opt-out form relied on iFrame technology which has become increasingly problematic due to browser changes and restrictions on setting third-party cookies.

  With our privacy-first approach, we’ve known for some time that we would eventually need a new way to provide this important opt-out functionality that would work most reliably in the myriad of contexts our users rely on it for.

  Embedding the opt-out form

  Matomo 4.12.0 introduces an improved opt-out. This provides two new options for embedding the opt-out on your website, either using the Matomo tracker code or as self-contained code.

  

  As with the iFrame method, the built-in opt-out code can be styled in Matomo to match your website, and provides a snippet which you can add to your website to show the opt-out feature to your users.

  Find out how to customise the opt-out form.

  Customising the opt-out form

  

  What does this mean for existing opt-out forms ?

  Although it is no longer possible to generate new iFrame embed code using the Matomo UI, the underlying opt-out feature is still fully supported and any existing iFrame opt-out form code embedded in websites will still work as before. It is recommended to migrate to one of the new opt-out form options as browser support for the iFrame opt-out will continue to decrease.

  To read more in depth information about the new opt-out functionality please refer to our new developer documentation for tracking opt-out.
