Hi,

I need to make the window size of my gstreamer video smaller than full screen.
I need to view two cameras on the same HDMI screen (1920x1080). (for the left camera and the right camera)
my original video resolution is 720x480.
how may I change the width and the height of the window?
I am using apalis-imx8, ixora carrier board, with OS multimedia image. BSP5.

this command is working fine but with full screen window:
gst-launch-1.0 rtspsrc location=rtsp://172.22.0.195:554/h264 latency=150 ! decodebin ! autovideosink

I have used this command:
gst-launch-1.0 rtspsrc location=rtsp://172.22.0.195:554/h264 latency=150 ! decodebin ! videoscale ! video/x-raw,width=720,height=480 ! autovideosink

but it showed me window like this:

Hi @rama.aloufee ,

Thanks for using the Toradex community.
Could you please provide the exact model of the Apalis you’re using as well as the BSP version.

One question about the issue. On the image you sent, the displayed content is not even recognizable, is this not happening at all when using the first command?

In other words, with this command it displays properly but at fullscreen, which is not what you want. Right?

I also noticed that you have h264 in your command. Do you compress your camera feed?

Best Regards
Kevin

Hi @rama.aloufee !

Have you tried to come up with a gstreamer pipeline that is able to resize the video output on your own computer?

If you come up with a pipeline capable of doing this, please share it with us. This way we can try to tweak it and make the module do the same.

Best regards,

I have posted this command which was not working with imx8, but when using it with my laptop it is working properly " native ubuntu OS laptop". I can resize the window size here by changing the value of the width and the height in this command
