Comment (by cohosh):

 I rebased the changes made by sukhe and dcf onto a more recent version of
 Tor Browser: https://github.com/cohosh/tor-browser-build/tree/win-webrtc

 [https://github.com/cohosh/tor-browser-
 build/commit/6580d5b11809b1a29a4008a48dc48f9ca665cf42 This commit] fixes
 the error in comment:32. For some reason incremental builds of webrtc
 caused the video_capture module dependencies to be loaded, even though the
 module has been disabled in a previous patch.

 I'm currently getting some new build errors in WebRTC:
