Output video in desired coordinate on screen

[Abin P]

Hi all

I prepared a simple pipeline.
Gst-launch-1.0 filesrc location=sample.bgra ! Videoparse format=bgra width=640 height=480 ! Waylandsink
.when every time executing this pipeline video will appear at different coordinates on the screen.I want to display this video in a desired  position on the screen.How can i achieve it?.Is there any plugins have such property?.please help me to find out a solution for this problem.

Thanks and regards.
Abin

The automatically created windows by sinks are for debugging purposes
only. You have to write an actual application and embed the video sink
into a window created by your application. That way you have full
control.

Dear sebastian droge

Thanks for your reply.Actually i created two separate applications , videoplayer using qt as one application and video playback using gstreamer as other application.I like to render my video output frame on the desired coordinate of qt window. So display coordinate must be set by gstreamer.Help me to set coordinate using gstreamer.

Thanks and regards.

That's not a GStreamer problem then and out of scope for GStreamer. You
have to use whatever tools Qt gives you on your target platform for
embedding another application into your Qt window.

Hello, Abin

You can make appsink as a last element in your pipeline.

After this you can read buffer.

This buffer will contain your image.

And you can use it to display in your qt app.
