Tool/software: Linux

Hi,

We are using gstreamer on AM5728 to display the video.

The pipeline is as follows:

gst-launch-1.0 -v v4l2src device=/dev/video1 io-mode=4 ! 'video/x-raw, format=(string)YUY2, width=(int)1280, height=(int)720, framerate=(fraction)60/1' ! vpe num-input-buffers=8 ! 'video/x-raw, format=(string)NV12, width=(int)1280, height=(int)720, framerate=(fraction)60/1'! queue ! waylandsink

Please let us know that how can we set the position of the video window on screen?

software version: SDK-rt3.3 , gstreamer-1.0

Thanks,

Andi

Hello,

Command gst-inspect-1.0 waylandsink will print the available waylandsink properties.

Waylandsink does not support window positioning.

Waylandsink with desktop-shell supports always random positioning.

There is ivi-shell to support positioning, scaling , rotation etc but waylandsink with ivi-shell support is not available at this moment.

I would recommend you to check this thread for more information:

Hello Margarita,

Another question, can QtGstreamer help us to solve it?

Thanks

Hello,

I am not very aware with QT tool but per my understanding you want to creates a qt window and pass the handle to gstreamer. But in this case you should specify the (x, y) coordinates by the videosink element also.
Please check this thread about qt also:
e2e.ti.com/.../2356789
I would recommend you to check gstreamer videobox element also is it suitable for your requirement.

hello,

we find that videobox can't set position, but resize window. Is there another way left?
By the way, how can we make waylandsink with ivi-shell support possible?

Thank you Margarita.

There is no guide about gstreamer with ivi-shell.

But information about the ivi-shell could be found here:

processors.wiki.ti.com/.../Processor_Linux_SDK_Graphics_and_Display

Please check the link in my first answer for more information regarding gstreamer and ivi-shell.

Waylandsink is a open source pluginit is in the bad plugin under /tisdk/build/arago-tmp-external-linaro-toolchain/work/am57xx_evm-linux-gnueabi/gstreamer1.0-plugins-bad folder.

Best Regards,

Margarita
