            Bug ID: 245358
           Summary: [GStreamer][MSE] Avoid seeking in READY or NULL
                    pipeline state
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org

We should put the seek request on pending when the GStreamer pipeline is in a state below PAUSED state.

Because before the PAUSED state, the hardware devices are not ready to doing a seek and reset the devices, 
such as the video decoder, knowing that in the READY state we reserve and open the devices asynchronously.

We also need to avoid performing a new seek when another is pending, this behavior improves robustness when
performing many searches in a short period of time.
