// FIXME: We should likely rename this header file to WebRTCProvider.h because depending on the
// build configuration we create either a LibWebRTCProvider, or a GStreamerWebRTCProvider or
// fallback to WebRTCProvider. This rename would open another can of worms though, leading to the
// renaming of more LibWebRTC-prefixed files in WebKit.
