Regarding QML Video performance on embedded

[RobertB]

I have a potato (Orange Pi Zero2W), Qt6.6.1, and a 10mb .mp4 (1280x720, 2578 kb/s, h264).

Playing it via QML results in 1fps:

Video {
        id: video
        anchors.fill: parent
        source: "file:///tmp/test.mp4"
        fillMode: VideoOutput.Stretch
        muted: true
}

Backend is gstreamer 1.20.3.

I know my device is 'slow' but it should at least be able to play videos smoothly (?). Any tips on how to play a video smoothly from Qt?

Starting my application like this: QT_QPA_EGLFS_HIDECURSOR=1 LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/qt6/lib/ /root/qml_hello -platform eglfs

Edit: whoops, wrong forum category.
