UPD: Seems the problem is ***NOT IN QtMM***.. For example, when I have compiled an usual cpp-based QMediaPlayer example, and to set there: {quote} root@apalis-t30:~/Downloads# export QT_GSTREAMER_WIDGET_VIDEOSINK=nv_omx_hdmi_videosink root@apalis-t30:~/Downloads# export

Now, I have added this output: {code} qDebug() << "*** TEST Best sink name" << elementName << ", m_videoSink:" << m_videoSink; {code} to the ctor of QGStreamerVideoOverlay in file /src/gsttools/qgstreamervideooverlay.cpp, and now I see this output: {quote} root@apalis-t30:~/Downloads#

The solution from: https://devtalk.nvidia.com/default/topic/894891/jetson-tk1/gstreamer-1-0-and-qt5-video-playback/ with adding the: {code} qDebug() << "Setting videosink to " << videoSinkString; qputenv("QT_GSTREAMER_WINDOW_VIDEOSINK", videoSinkString.toUtf8()); {code} to the

Now, I have recompiled the QtMM plugin (with default gstreamer 0.10), but with adding of debug macro DEBUG_PLAYBIN. Then I got following log: https://paste.kde.org/p6ztesnsq Where I do not see any mentions about the selected gst sinks.. I see only this: {quote} Set video output:

> BTW: As I remember, I saw some environment variable which allows to setup custom video sink... I need to see sources of QtMM... if I'm not mistaked.. maybe it will help... I have found this env variables: * QT_GSTREAMER_WIDGET_VIDEOSINK * QT_GSTREAMER_WINDOW_VIDEOSINK and try to use it:

> Gstreamer 1.0+ goes some way to addressing these issues The Apalis T30 board has GPU from the NVidia. So, when I use 'gst-inspect' I see some of 'nv' sinks. So, as I understand, the easy ways to do it are: 1) I should try to use GStreamer 1.0 (instead of 0.10) "as is" with QtMM

Re: [Development] [QtMultimedia] How to make to use a HW codecs by QML media player on Linux?

The short answer is some amount of platform adaptation will be required to enable hardware acceleration on your board. Looking at the page you linked to; that adaptation might be achieved by creating an implementation of QGstBufferPoolPlugin (gstreamer 0.10 only) which exposes EGL surfaces
