Video rendering on qtwidget using gstreamer

Hi Team,

I want to render video on qtwidget using gstreamer.

For testing purpose I an running below gstreamer pipeline on my ubuntu mcahine.

gst-launch-1.0 videotestsrc ! qt5videosink

Here qt5videosink is a gstreamer plugin that is used to render video on qt widget.

But when I am running the above gstreamer pipeline, It is running but not opening any output widget.

Logs :

User-2:~$ gst-launch-1.0 -v videotestsrc ! qt5videosink Setting pipeline to PAUSED ... Pipeline is PREROLLING ... /GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0.GstPad:src: caps = video/x-raw, format=(string)BGRA, width=(int)320, height=(int)240, framerate=(fraction)30/1, multiview-mode=(string)mono, pixel-aspect-ratio=(fraction)1/1, interlace-mode=(string)progressive /GstPipeline:pipeline0/GstQtVideoSink_qt5:qtvideosink_qt5-0.GstPad:sink: caps = video/x-raw, format=(string)BGRA, width=(int)320, height=(int)240, framerate=(fraction)30/1, multiview-mode=(string)mono, pixel-aspect-ratio=(fraction)1/1, interlace-mode=(string)progressive Pipeline is PREROLLED ... Setting pipeline to PLAYING ... Redistribute latency... New clock: GstSystemClock ^Chandling interrupt. Interrupt: Stopping pipeline ... Execution ended after 0:00:05.508780834 Setting pipeline to NULL ... Freeing pipeline ...

Someone please help me here how can I achieve this?

Thanks.

Hello @himanshu_bhavani,

I hope you are doing well.

I have a few queries to ask, Please find them below.

Which i.MX EVK/Custom board are you using?
What Linux BSP are you using?
Please share the console logs along with the sequence of the command you run.
Please also share the environment details. (i.e. display number and so on..)

Thanks & Regards,
Sanket Parekh
