Hi all,
I'm trying to render a playback pipeline to a Qt based video sink: qmlglsink
My simple app is based on gst-example.
I have recompile successfully gstreamer 1.18.4 using meson build.
The qmlglsink plugin is successfully built and checked in gst-inspect-1.0
In my app, I have applied the gst-examples recommendation, that is:
/ /* the plugin must be loaded before loading the qml file to register the
* GstGLVideoItem qml item
* FIXME Add a QQmlExtensionPlugin into qmlglsink to register
GstGLVideoItem
* with the QML engine, then remove this
*/
GstElement *sink = gst_element_factory_make ("qmlglsink", nullptr);
gst_object_unref(sink);/
It works, sink variable is not null.
Afterward, the following lines failed:
/
QQmlApplicationEngine engine;
engine.load(QUrl("qrc:/main.qml"));/
and main.qml looks like:
/import QtQuick 2.0
import org.freedesktop.gstreamer.GLVideoItem 1.0
Item {
GstGLVideoItem {
id: video
objectName: "videoItem"
anchors.fill: parent
}
}/
Unfortunately, I spet hours with the same errors in the console:
QQmlApplicationEngine failed to load component
qrc:/main.qml:3:1: module "org.freedesktop.gstreamer.GLVideoItem" is not
installed
I have set the QML_IMPORT_PATH and QML2_IMPORT_PATH accordingly...but I stil
get the same error.
I'm running under Windows 10.
I have checked everything relevant...am I missing something ?
Any suggestion will be kindly welcome ;)
K.
