 lose many of the benefits of the webp format itself since you are
 downsampling to a 256 color palette initially. What I would like to do is
 go straight from video to animated webp via ffmpeg. However, this doesn't
 seem to be possible at the moment. I've opened a ticket on their end :
 https://trac.ffmpeg.org/ticket/3760 but would like to know if a patch on
 the libwebp end would enable this feature in ffmpeg or not.

 This work would be fully in ffmpeg, libwebp currently only handles single
 frames. In gif2webp for instance we use libwebp for compression and
 libwebpmux for the final assembly. A simple video frame encoder could do
 the same in ffmpeg, apng/gif conversion may be a bit more difficult to get
