QMediaPlayer Performance on Nvidia Jetson nano
-
Hi,
Im implementing a multiple screen player with QMediaPLayer over QGraphicsView and the performance dropped nearly 50% when i try to play 2 video on 2 QGraphicsView (total of 2 view that is playing video). The Jetson nano Ubuntu desktop when playing the same video with player that comes with it on 2 separate process/app can still maintain 30 FPS while the QT app fluctuates between 12 to 18 FPS.
Im cross compiling with QT 15.5.6 and im also using QMediaPlayer with Gstreamer that uses Nvidia Jetson nano HW decoder over qtvideosink. Can someone provide any comment how or what is the best way to improve the pipeline with QT? thanks
