[Interest] Does QMediaPlayer use soft render?

[nus1998]

Hi All,


I'm running a i.MX6Q sabresd board from NXP, and the Qt version is 13.2.



When I play video by "qmlvideo" in example, the display is smooth, while use "player" in qtmultimediawidget example, it's very slow.
If I specify the video sink by export QT_GSTREAMER_WIDGET_VIDEOSINK=imxv4l2sink, overlaysink or xvimagesink, "player" plays movie smooth too, but the size is out of the widget area, I guess the output is not QVideoWidget again.


I wonder is it a bug or just such a feature and only qml engine support hw video sink?


Thanks in advance

Nus
