Is this the correct default?

Should this be "#if PLATFORM(COCOA) && ENABLE(MEDIA_STREAM"?

"RemoteMediaRecorders" is a bit subtle and easy to confuse with "RemoteMediaRecorder". Maybe something like "RemoteMediaRecorderManager" instead?

I think so, I am not sure we will enable MediaRecorder by default without GPUProcess.

OK, will go with manager.

Actually, I implemented it now using m_errorCallback, will remove this FIXME.
