Looks good. Please address my concerns and we can get this landed!

> Source/WebCore/ChangeLog:8
> +

Add a statement like:

"Prevent the MediaSource engine from being used to process MediaStreams, since they are not compatible"

> Source/WebCore/ChangeLog:10
> +        Changed MediaStream to never be loaded

Move this explanation down to line 11, where you were saying "Ditto".

> Source/WebCore/ChangeLog:11
> +        (WebCore::MediaPlayerPrivateAVFoundationObjC::supportsType): Ditto

Remove Ditto from this line.

> Source/WebCore/ChangeLog:14
> +        * platform/graphics/avfoundation/objc/MediaPlayerPrivateMediaSourceAVFObjC.mm: Ditto

Remove 'Ditto' from this line.

> Source/WebCore/platform/graphics/avfoundation/objc/MediaPlayerPrivateMediaSourceAVFObjC.h:99
> +    virtual void load(MediaStreamPrivate*) override { setNetworkState(MediaPlayer::FormatError); }

No need for virtual here. "override" takes care of that. I think you should move this implementation inside of MediaPlayerPrivateMediaSourceAVFObjC.mm.
