• 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.

• Ffmpeg x265 error : "Color Primaries must be", "ransfer Characteristics must be", "Matrix Coefficients must be" [closed]

  16 septembre 2022, par Mister Sir

  I'm trying to do the following conversion :

  


  ffmpeg -i video.mp4 -map 0 -c copy -c:v libx265 -crf 30 -vf "scale=-1:\'min(720,ih)\'" -c:a libopus -b:a 44k -map_metadata 0 -loglevel error -hide_banner video.mkv


  


  This works fine except for a specific video. I'm getting the following output :

  Can't find a single result when I google the first error text, ffmpeg "Color Primaries must be unknown"

  


  This is the verbose output :

  I'm not an expert at video encoding, so I don't really know what this all means. Probably something with the source file. How to get around this ? Thanks in advance ! If I need to upload the video, let me know how I can do that.

  I am trying to create a DASH manifest and segments from an .mp4 file. I have created a bash files with the commands below, and calling bbb.mp4, but the output gives the error on the subject line. This is the script I am using :
