 // Chrome for Android seek message sequence is:
 // 1. Renderer->Browser MediaPlayerHostMsg_Seek
 //    This is the beginning of actual seek flow in response to web app requests
 //    for seeks and browser MediaPlayerMsg_SeekRequests. With this message,
 //    the renderer asks browser to perform actual seek. At most one of these
 //    actual seeks will be in process between this message and renderer's later
 //    receipt of MediaPlayerMsg_SeekCompleted from the browser.
 // 2. Browser->Renderer MediaPlayerMsg_SeekCompleted
 //    Once the browser determines the seek is complete, it sends this message to
 //    notify the renderer of seek completion.
