The libwebp API doesn't match very well with the GstVideoEncoder API, as it only delivers an unframed bitstream once all pictures have been processed, which means we can only push a single buffer manually on our srcpad on finish(). Supporting animated webp is still valuable, and the feature is behind an opt-in property. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5994>
