These are necessary violations of style, and are explained in the comments in the source file.

Oops :-O

Should this be a PassRefPtr<>?

> Source/WebCore/platform/graphics/avfoundation/cf/MediaPlayerPrivateAVFoundationCF.cpp:927
> +#ifndef NDEBUG
> +    RetainPtr<CFURLRequestRef> urlRequest = AVCFAssetResourceLoadingRequestGetURLRequest(avRequest);

Did you mean to LOG() the scheme? If not, what does this code do?

> Source/WebCore/platform/graphics/avfoundation/cf/MediaPlayerPrivateAVFoundationCF.cpp:1799
> +    String keyURI = keyURIRef.get();

This is only used inside of #if ENABLE(ENCRYPTED_MEDIA_V2) so it will fail in a release build if ENABLE_ ENCRYPTED_MEDIA_V2 isn't defined.
