    Description

      See https://testresults.qt.io/grafana/d/d8bebf9c-6e1c-4bff-a214-8d506943f23c/new-flaky-crashed-failed-tests?var-branch=1&var-test_case_n=1407&var-test_function_n=146331&var-group_by_interval=1d&orgId=1&from=now-7d&to=now&timezone=browser

      Is it always tst_QMediaPlayerBackend::play_playbackLastsForTheExpectedTime(file qrc:/testdata/busMpeg4.mp4, loops 2, rate 1, pause before 1) 'abs(duration - expectedDuration) < 600ms' returned FALSE. (expected duration: 2000ms, actual duration: 1017ms) that fails?

      From the logs I looked at, it seems like playback of 2 loops, at rate 1, with pause before results in too fast playback, as if it is only played once.
