Sink elements lose their states entering ASYNC PAUSED->PAUSED transition. Calling HTML video.pause() during a seek doesn't result in pipeline state change call as player reports it's paused already. Forcing gst_element_set_state() doesn't really help in this case as pipeline enters inconsistent state after a seek that everything is playing but sinks are paused. In addition, triggering playbackStateChanged() at seek end causes HTMLMediaElement::playInternal() that cleans up all signs of previous pause() call. Don't emit playbackStateChanged() at seek end so HTML won't force playInternal() and HTMLMediaElement will call pauseInternal() again after a seek (from updatePlayState()). This fixes following scenario: video.currentTime = x.xx video.play(); setTimeout(()=>{ video.pause(); }, 1} // ensure async duringn a seek (video didn't pause after initial seek had finished) See: https://github.com/WebPlatformForEmbedded/WPEWebKit/pull/1013 1932690 1 eocanha 2023-02-10 10:36:04 -0800 Pull request: https://github.com/WebKit/WebKit/pull/9934 1933837 2 ews-feeder 2023-02-15 09:05:55 -0800 Committed 260314@main (5d8787383e48): <https://commits.webkit.org/260314@main> Reviewed commits have been landed.
