Dear Web Security Interest Group,

The WebRTC Working Group is working toward publishing the Media Capture
from DOM Elements API to Candidate Recommendation and is thus seeking
review from a variety of groups of the document:


We are particularly interested on feedback from the Web Security 
Interest Group on the impact on security (and the proposed
mitigations) to the capability introduced with this spec (i.e. capturing
what is rendered in a DOM element into a MediaStream, which in turn can
be e.g. Recorded, transmitted in real time using WebRTC etc.). One
specific area of interest regarding privacy is the handling of isolated
or tainted content being rendered.

We of course also welcome feedback on any other aspect of the

We would appreciate to receive feedback before January 12, 2018. We hope
to request transition to Candidate Recommendation early next year.

If you have any comments, we prefer that you submit them as Github issues:


Alternatively, you can send your comments by email to


For the WebRTC chairs,
Stefan Hakansson
