Thanks for this a heads up. AVIF support in webkit is experimental, not for production. Definitely, we will consider bumping up the versions of libavif and dav1d.</thetext>

    <thetext>Also most of our (GTK/WPE) build bots now rely on the Flatpak SDK for dependencies. It&apos;s less easier to update though, I can take care of it in a follow-up patch.</thetext>

&gt; production. Definitely, we will consider bumping up the versions of libavif
&gt; and dav1d.

Maybe we can consider enabling it by default for the next cycle though? 2.34 scheduled for September/October 2021.</thetext>

    <thetext>I used the GitHub mirror to create and test this patch, haven&apos;t used SVN before, if someone could generate a ChangeLog file for me that would be awesome, otherwise I will dive in next week. It&apos;s a very small change, so if anyone wants to patch it themselves using the correct WebKit procedures, feel free to do so.

Targeting AVIF support enabled by default would be a great goal! It&apos;s tricky though, and will need a lot of testing, Firefox had to roll back for the 86 release for example: https://bugzilla.mozilla.org/show_bug.cgi?id=1682995#c22

Should we create a tracking issue for enabling AVIF decoding by default?</thetext>

There is a Tools/Scripts/prepare-changelogs script. It will create the skeleton that you need to fill.</thetext>
