 New Comment:

Indeed, animated WebP (I think extended WebP in general) is not
(yet) supported.  You would need to demux the stream first.  This
has to be documented.

Besides the missing documentation, this is a libgd issue, so
please report upstream[1] (unless there is already a respective
issue).  Thanks.

Description:
------------
The error "gd-webp cannot allocate temporary buffer " seems to occurs when using
"imagecreatefromwebp" on an *animated* webp image. 

For example this one : https://media1.giphy.com/media/Lm5hxmmI6ucOQGfjKj/200w.webp
