Webp support for thumbnails

[vitormmatos]

Webp is currently a more compact format than jpeg when on lossy compression, same with PNG and lossless compression:

Is it possible and viable to implement it for usage on thumbnails with the ogg container, either video or audio?

In Ogg metadata is attached to specific compressed formats, not the overall container.

It should work to put image/web in a METADATA_BLOCK_PICTURE tag in an Opus file, also the reference encoder app only has specific support for png/jpeg/gif.
