Could not write header for output file #0 (incorrect codec parameters ?) : No such file or directory Error initializing output stream 0:5 —
13 septembre 2022, par M EI 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 :


ffmpeg -re -i bbb.mp4 -map 0 -map 0 -c:a aac -c:v libx264 \
-b:v:0 800k -b:v:1 300k -s:v:1 320x170 -profile:v:1 baseline \

-window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" \
-f dash /path/to/out.mpd



After running the command for my bash file dash-demo I get :

Ffmpeg x265 error : "Color Primaries must be", "ransfer Characteristics must be", "Matrix Coefficients must be" [closed]
16 septembre 2022, par Mister SirI'm trying to do the following conversion :

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

Introducing Improvements to the Opt-Out Form Feature
18 septembre 2022, par Ben — AboutMatomo 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.
