This should preferably be posted in the oEmbed BP forum:
https://buddypress.org/community/groups/oembed-for-buddypress/forum

But anyway… yup it should be possible.

Would have to write a custom activity fetch routine to do this. Might add this for oEmbed for BP 0.7 (that’s right, I’m talking about 0.7 before 0.6 is officially released!).

Re: thumbnails – I’m working on support for that for v0.6. Not all providers will return thumbnails. YouTube will work though.
