XF 2.3 gif to webp optimization problems

[ge66]

I'm on php8.2 and have chosen the Imagemagick PECL extension (Imagick compiled with ImageMagick 6.9.11-60 Q16 x86_64 2021-01-25 https://imagemagick.org)

I ran the CLI image optimization and got rid of some GBytes.

When I look for the biggest files there are still a lot of animated gifs there, I thought they would have been converted to webp animation?

Animated gifs cannot be converted to webp, since they would lose their animation iirc.

but third party;

So webp can be animated, just as png ;

EDIT: my embed breaks the xen proxy?

I understood it that it would be possible if you use imagick but not with gd. From this post by @Jeremy P

This is kind of subtle. We don't actually attempt WebP conversion for GIFs when using the GD image driver due to its lack of support for GIFs/animated WebP. However, it was being loaded into GD and saved back afterwards anyway, which caused the animation to be lost.

Note that GIFs which exceed the maximum dimensions will still lose their animation when resized with the GD image driver, which is unavoidable (and happens even in XF 2.2). Using Imagick should retain the animation (and convert to animated WebP, where enabled and supported).

What version of both ImageMagick and the Imagick PHP extension are you using? You need at least ImageMagick 7.0.8-68 compiled with WebP support. And we discard the result if ImageMagick reports back that the conversion failed for any reason.

Not if they are converted to animated webp.

Ok, thank you. That is probaly the problem then, as I wrote earlier I have Imagick compiled with ImageMagick 6.9.11-60 Q16 x86_64 2021-01-25.
I will ask the people that manages the server to update that.

I guess I then just rerun the optimization and the gifs will be fixed?

 

[Jeremy P]

Aye I think that should do it.

what in Xenforo 2.3 changed the requirements to minimum ImageMagick 7.0.8 ?

The conversion of GIFs into animated WebP. It’s not required, they will just be skipped over otherwise.

My server is running Debian stable and therefor they say that they wont't update to ImageMagick 7 as it's still experimental in Debian.
So I guess I'll have to wait a while to fix this.
