Not a problem, but is there any reason of why you're setting all the values
here? Even if it is, it should be consistent with StreamOptions::VideoOption and
other enums in other files if possible.

Personally, I wouldn't set all the values, especially the counting one, but
that's up to you.

It was to explicitly show the number for, kNumMediaStreamTypes, which I agree is
not necessary and, in general, I do prefer the other convention over this.
Changed.

+  kVideoCapture = 2,
+  kNumMediaStreamTypes = 3
 };
 
 // StreamDeviceInfo describes information about a device.
