consider making this a protocol so that one day when we have time for unit tests
we can do it more easily.

@protocol RTCRtpSender : NSObject

parameters, track

@end

@class RTCRtpSender : NSObject <RTCRtpSender>
@end

Done.

is this valuable? If it fails we won't know why. Is there any meaningful error
handling that can happen?

[skvlad, 2016/04/05 23:21:28]

It's only valuable in letting you know if the changes had effect or not. There
is no error code returned that tells you what exactly went wrong.
