VideoCaptureCapabilities? does this typedef already exist somewhere maybe?

Yes, it exists in webrtc device_info_impl.h, but that's webrtc @ third_party.

I chose VideoCaptureFormats because, in time, VCC could/should/ought to be
removed and all simplified to just VCFormat, like ncarter@ and you pointed out.
