@protocol RTCVideoCapturerDelegate <NSObject>

Done.

The RTC_EXPORT should appear before this one, not the protocol I think.

[magjed_webrtc, 2017/04/10 12:12:50]

I think I need it for both actually.

+- (instancetype)initWithDelegate:(id<RTCVideoCapturerDelegate>)delegate;
+@property(nonatomic, readonly, weak) id<RTCVideoCapturerDelegate> delegate;

style: properties before methods

add blank lines to make it more readable

[magjed_webrtc, 2017/04/10 12:12:50]

Done.
