Ability to extract the src url from {{ video.embed_code }}

[sethburtonhall]

I have a need to get the src url from the iframe when embedding via {{ video.embed_code }}

Ideally {{ video.embed_code_url }} or {{ video.embed_src }} or the like.

I've just taken over Embedder to update it for Craft 3. I'm closing old issues so we can have a fresh start, but let me know if you want to revisit the issue and I can have a look into it. Thanks!
