Bug ID: 51153
           Summary: A winegstreamer change caused a new quartz:filtergraph
                    failure in Wine
           Product: Wine
           Version: 6.8
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: winegstreamer
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

quartz:filtergraph started failing in Wine on 2021-04-26:

http://winetest.dolphin/data/patterns.html#quartz:filtergraph

filtergraph.c:440: Test failed: GetState() failed: 40237

Strangely this failure only happens on the TestBot's debiant2 VM.

A bisect showed this failure to be caused by the patch below:

winegstreamer: Allow setting the stop position to the stream duration.

Since we no longer stop the GStreamer pipeline, it does not reset the stop
position for us. Fixes a hang during intro video playback in RC Cars.
