With MSE in a Worker, the threading model of the MSE objects will be changing. Currently, all run in the main thread. As we progress bug 264134, the threading model will become: HTMLMediaElement, MediaPlayer, MediaPlayerPrivate run on the main thread (MediaPlayerPrivate run in the GPU process). MediaSource and SourceBuffer will run on either the main thread or in a worker. MediaSourcePrivate and SourceBufferPrivate will run in a dedicated WorkQueue (either in the content process or in the GPU Process). Currently, MediaSource (a MediaSourcePrivateClient) and SourceBuffer (a SourceBufferPrivateClient) are using non-thread safe refcounting and supports weakptr. MediaSourcePrivate and SourceBufferPrivate are using non-thread safe refcounting and supports weakptr. We want to make them use thread-safe refcounting and thread safe weakptr.
