setExif: would create a CFDictionary using NULL for keyCallBacks and
valueCallBacks. This has the effect of comparing the keys of the
dictionary by pointer instead of by value. With ld64, this works
because it always dedupes identical constant CFSTR("foo") literal,
but lld currently doesn't do this.
Using kCFTypeDictionaryKeyCallBacks and kCFTypeDictionaryValueCallBacks
fixes the problem with lld and is "more correct" in general: Now the
dictionary would work with computed CFStrings too, it shows up better
in CFShow() output, etc.
While here, also fix a memory leak in setExif:.

WebRTC Obj-C SDK
This directory contains the Obj-C SDK for WebRTC. This includes wrappers for the C++ PeerConnection API and some platform specific components for iOS and macOS.
Organization
-
api/
Wrappers around classes and functions in the C++ API for creating and configuring peer connections, etc.
-
base/
This directory contains some base protocols and classes that are used by both the platform specific components and the SDK wrappers.
-
components/
These are the platform specific components. Contains components for handling audio, capturing and rendering video, encoding and decoding using the platform's hardware codec implementation and for representing video frames in the platform's native format.
-
helpers/
These files are not WebRTC specific, but are general helper classes and utilities for the Cocoa platforms.
-
native/
APIs for wrapping the platform specific components and using them with the C++ API.
-
unittests/
This directory contains the tests.
