qtvideosink not work on embedded target

qtvideosink

hello,

I'm trying to develop app using custom gstreamer pipeline, with below example, I'm able to run it on PC ubuntu, but not on embedded, I really wonder what does qtvideosink depend on?

import QtQuick 2.0
import QtMultimedia 5.12

Item {
MediaPlayer {
id: mediaplayer
source: "gst-pipeline: videotestsrc ! qtvideosink"
autoPlay: true

VideoOutput {
    anchors.fill: parent
    source: mediaplayer
}

}

I feel like this could relate to opengl, let me know how I debug it?

but not on embedded

What happens there?
You should first check whether the plug-in are properly loaded: set QT_DEBUG_PLUGINS env variable, run the application and check its output (see https://doc.qt.io/qt-6/debug.html).

QT_DEBUG_PLUGINS

hello jsulm,

actually every looks good from the log perspective, the only problem is when I run app, there's only a empty windows without videotestsrc rendering. check the below log with QT_DEBUG_PLUGINS set to 1. also in the qml I have print mediaplayer status.
from below it change from 2 to 6, still quite good.

btw, I'm not able to attach log directly via code style, it is detected as spam, I don't know why.
so I paste it here qtvideosink-debug-plugin
