? This does not seem to have anything todo with constraints?

[perkj_chrome, 2012/10/04 08:24:59]

oh - I see. But media_stream_request.h is not used in the render process. Ie -
none of the types below are used. Move these to media_stream_options.h and
please add a comment about what it is.

Done.

[justinlin, 2012/10/08 08:59:45]

Done.

Actually, I need access to access these from chrome/, would it make sense to
move mode_stream_request.h into the public interface of content/? Or, should I
move these 2 constants back to media_stream_options?
