Yes, I know that Rodolfo knows the mistake. But it is certainly helpful if this is in here again.

 

[DeCysos]

Here are a few examples as animated webp

https://beta.pfs.red/testpics/animated-butterfly.webp

and

https://beta.pfs.red/testpics/animated-computer.webp

It seems that animated WebP images are problematic. As for GD, the issue is here: https://github.com/libgd/libgd/blob/master/src/gd_webp.c#L145
Also, I tried with Imagick and I got @ error/webp.c/ReadWEBPImage/338

 

[DeCysos]

If it is not possible to upload or process animated webp images with the current software, there is only the option to prohibit them
But this will certainly not inspire everyone.

php:
[CODE lang="php" title="Recognize animation (webp)"]function isWebpAnimated($src){
$webpContents = file_get_contents($src);
$where = strpos($webpContents, "ANMF");
if ($where !== FALSE){
// animated
$isAnimated = true;
}
else{
// non animated
$isAnimated = false;
}
return $isAnimated;
}[/CODE]

Javascript:
[CODE lang="javascript" title="Recognize animation (webp)"]function isWebpAnimated(src) {
var request = new XMLHttpRequest();
request.open('GET', src, true);
request.addEventListener('load', function () {
if(request.response.indexOf("ANMF") != -1){
// animated
alert(true);
}
else{
// non animated
alert(false);
}
});
request.send();
}[/CODE]

But In case of large images PHP and Javascript not working well, So best Solution is to use Shell Script, If you have Ubuntu.
Shell Script:
echo $(grep -c "ANMF" ~/animated.webp)
return 0 if non animated, else non zero value for animated.


But maybe that will help you.

I found the following interesting article.

Convert JPG, PNG, and Animated GIF to WEBP

New image formats like WEP and MOZJPEG will be a major boost to load time on the web. The majority of page load and render time is usually attributed to

Thanks for the info, but the problem is not the detection of the animated frames.

The problem is that the gd library is not handling the creation of an animated webp image as an image resource.

 

[DeCysos]

It looks like it will only work with the cwebp and webpmux extensions.

But I'm not a professional there.
However, I have found nothing else on the subject.
This is easier for static images.

I also ended up with references to these extensions but what is really odd is that there's still no support for GD / ImageMagick out of the box, even if you compile it with support for it.

 

[DeCysos]

Yes, I also noticed that the extension for webp must also be available at GDLib.
Unfortunately, this is not the case for many hosters, which in turn will lead to many Chevereto customers reporting the errors.

The stupid thing is that you have to recompile php if you want to have webp support. For Plesk users, unfortunately, this is made more difficult by the fact that Plesk webp does not yet support it.
Every time php is updated by Plesk, the manually compiled php is replaced again. (At least that's how I read it).

At first there will be nothing left but to do without animated webp images.

I also read somewhere that it should work with ffmpeg. But I'm not sure whether the webm format was meant after all.

I haven't made up my mind about ImageMagick yet.
But with certainty.

Unfortunately there are not too many pioneers at the moment via webp
At least not for animated images which should also run on customers' servers.
