* Fix a deadlock when changing the video outputLars Knoll2021-05-261-0/+5
| | | | | | | | | | | | | | | | | Changing the videooutput and deleting the mediaplayer directly afterwards could lead to a deadlock, as the videosink was blocking on a pad and then calling a slot on the main thread using a blocking queued connection. If the main thread was changing the state of the gst pipeline at the same time, this could lead to a deadlock. Avoid it by pausing the pipeline before changing the video output.

* Pass the remaining mediaplayerbackend autotestsLars Knoll2021-05-071-0/+18
| | | | | | | | | | | | | | | * Add a notification mechanism to the pipeline so the video output knows when QMediaPlayer is in a stopped state (using QProperty), as we want the pipeline to be in a paused state internally, but not get preroll frames if we're in paused externally. * Properly emit metadataChanged() signals, and ensure we're in GST_STATE_PAUSED before trying a seek.

* Various reliability bugfixesLars Knoll2021-04-191-5/+1
| | | | | | | | | Fix crashes due to dangling pointers. On gstreamer avoid using message filters when we do not need them. Change-Id: I1bce271dda4b5efb3913954deb719542288b9b12 Reviewed-by: Doris Verria <doris.verria@qt.io> Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* Clean up most QAbstractVideoSurface usagesLars Knoll2021-04-061-26/+0
| | | | | | | | | | The class is scheduled to be removed, once all it's usages are gone. QVideoSink is the replacement going forward. Change-Id: Idc0a4133496839bf9f95aa9bcf7d6d37cacd549b Reviewed-by: Doris Verria <doris.verria@qt.io> Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* Remove the videoscale element from the gst output handlingLars Knoll2021-04-061-5/+4
| | | | | | | | | | | We don't need it. Either we render to a window which can in all cases scale itself, or we do render QVideoFrames, and then the scaling might just as well be done at the end to avoid one additional memory copy.
