| // 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. |
| // |
| // Other seek-related IPC messages: |
| // Browser->Renderer MediaPlayerMsg_SeekRequest |
| // Browser requests to begin a seek. All browser-initiated seeks must begin |
| // with this request. Renderer controls actual seek initiation via the normal |
| // seek flow, above, keeping web apps aware of seeks. These requests are |
| // also allowed while another actual seek is in progress. |
| // |
| // If the demuxer is located in the renderer, as in media source players, the |
| // browser must ensure the renderer demuxer is appropriately seeked between |
| // receipt of MediaPlayerHostMsg_Seek and transmission of |
| // MediaPlayerMsg_SeekCompleted. The following two renderer-demuxer control |
| // messages book-end the renderer-demuxer seek: |
| // 1.1 Browser->Renderer MediaPlayerMsg_DemuxerSeekRequest |
| // 1.2 Renderer->Browser MediaPlayerHostMsg_DemuxerSeekDone |
| |
| // Only in short-term hack to seek to reach I-Frame to feed a newly constructed |
| // video decoder may the above IPC sequence be modified to exclude SeekRequest, |
| // Seek and SeekCompleted, with condition that DemuxerSeekRequest's |
| // |is_browser_seek| parameter be true. Regular seek messages must still be |
| // handled even when a hack browser seek is in progress. In this case, the |
| // browser seek request's |time_to_seek| may no longer be buffered and the |
| // demuxer may instead seek to a future buffered time. The resulting |
| // DemuxerSeekDone message's |actual_browser_seek_time| is the time actually |
| // seeked-to, and is only meaningful for these hack browser seeks. |
| // TODO(wolenetz): Instead of doing browser seek, replay cached data since last |
| // keyframe. See http://crbug.com/304234. |
