[Trisquel-users] Free-software-compatible oEmbed service for videos?

[leestrobel]

So, I have an account on Diaspora and I wanted to post a video to share with  
some family and friends. However, it seems that you can't upload videos  
directly there (which is fair enough, as it takes a lot of storage space).  
But, it seems that you can embed videos that have been uploaded to another  
video-hosting service that uses the oEmbed protocol, to allow the video to be  
embedded from there into Diaspora. The oEmbed Wikipedia article lists some  
services that offer oEmbed (which includes Facebook, YouTube, Vimeo).

Does anyone know if any of the services listed are free-software/privacy  
respecting or, if not, if there are any other services that offer oEmbed that  
are?
