"GStreamer-CRITICAL" after loading qmediaplayer's libs and plugins

[SGaist]

Looks like the libs not the plugins. Search for something like gstreamer1.0-plugins-*

@SGaist Hi,
I have copied into my target all gst-plugins* .so files as you mention above but nothing change.
Anything else that I can check?

It's going to be a silly question but, are these plugins of the right architecture ?

[IL]

@SGaist Hi,
If you asking about gst-plugins compilation, so all of the compilation done with my toolchain of-course.
Is there spacific location for them or /usr/lib is good enough?

My target working with Linux FB, is that an issue? Because I have another log that show "No m_videoSink available"
When i have searched for that log i saw the code below in
qtmultimedia/src/gsttols/qgstreamervideowindow.cpp and it concern me

if (elementName) {
m_videoSink = gst_element_factory_make(elementName, NULL);
} else if (QGuiApplication::platformName().compare(QLatin1String("xcb"), Qt::CaseInsensitive) == 0) {
// We need a native X window handle to be able to use xvimagesink.
// Bail out if Qt is not using xcb (the control will then be ignored by the plugin)
m_videoSink = gst_element_factory_make("xvimagesink", NULL);
}

if (m_videoSink) {
...
}
else
qDebug() << "No m_videoSink available!";
Dose QtMultimedia gstreamer-1.0 support has been written for xcb and No eglfs, linuxfb, directfb, etc is available?

Best regards,
IL

What SGaist asked is: did you compile the plugins for ARM architecture?
Is your toolchain for cross-compilation for ARM?

[IL]

@jsulm Hi,
Sure, all are cross-compiled for my ARM target using my toolchain as I mention in the first line.

[SGaist]

I don't know exactly where your custom gstreamer expects its plugins but you have some information about that here

[IL]

Thanks SGaist ,
What about my question above...
Dose QtMultimedia gstreamer-1.0 support has been written for xcb and No eglfs, linuxfb, directfb, etc is available?
Can someone give information about that?

[SGaist]

AFAIK it't not dependent on the QPA plugin

You can use the "Topic Tool" button for that :)
