  77 // Chrome for Android seek message sequence is:
  78 // 1. Renderer->Browser MediaPlayerHostMsg_Seek
  79 //    This is the beginning of actual seek flow in response to web app requests
  80 //    for seeks and browser MediaPlayerMsg_SeekRequests. With this message,
  81 //    the renderer asks browser to perform actual seek. At most one of these
  82 //    actual seeks will be in process between this message and renderer's later
  83 //    receipt of MediaPlayerMsg_SeekCompleted from the browser.
  84 // 2. Browser->Renderer MediaPlayerMsg_SeekCompleted
  85 //    Once the browser determines the seek is complete, it sends this message to
  86 //    notify the renderer of seek completion.
  87 //
  88 // Other seek-related IPC messages:
  89 // Browser->Renderer MediaPlayerMsg_SeekRequest
  90 //    Browser requests to begin a seek. All browser-initiated seeks must begin
  91 //    with this request. Renderer controls actual seek initiation via the normal
  92 //    seek flow, above, keeping web apps aware of seeks. These requests are
  93 //    also allowed while another actual seek is in progress.
  94 //
  95 // If the demuxer is located in the renderer, as in media source players, the
  96 // browser must ensure the renderer demuxer is appropriately seeked between
  97 // receipt of MediaPlayerHostMsg_Seek and transmission of
  98 // MediaPlayerMsg_SeekCompleted. The following two renderer-demuxer control
  99 // messages book-end the renderer-demuxer seek:
 100 // 1.1 Browser->Renderer MediaPlayerMsg_DemuxerSeekRequest
 101 // 1.2 Renderer->Browser MediaPlayerHostMsg_DemuxerSeekDone
 102
 103 // Only in short-term hack to seek to reach I-Frame to feed a newly constructed
 104 // video decoder may the above IPC sequence be modified to exclude SeekRequest,
 105 // Seek and SeekCompleted, with condition that DemuxerSeekRequest's
 106 // |is_browser_seek| parameter be true. Regular seek messages must still be
 107 // handled even when a hack browser seek is in progress. In this case, the
 108 // browser seek request's |time_to_seek| may no longer be buffered and the
 109 // demuxer may instead seek to a future buffered time. The resulting
 110 // DemuxerSeekDone message's |actual_browser_seek_time| is the time actually
 111 // seeked-to, and is only meaningful for these hack browser seeks.
 112 // TODO(wolenetz): Instead of doing browser seek, replay cached data since last
 113 // keyframe. See http://crbug.com/304234.
