AM5728: How to Clean up waylandsink ?

Bohan Zheng1

Part Number: AM5728

Hi TI,

I am trying to implement a camera switching feature without killing the waylandsink because otherwise the video streaming comes up to the top and covers our GUI.

I got the changing elements working and it can successfully switch camera for 50+ times and then killed by kernel. I know the right way to clean up an element is to set its state to NULL, I tried that on waylandsink but it also brought the video streaming to the top layer. It could do more than 50+ times switching though.

Is there any leaner way of cleaning up an element? Thank you in advance.

In the first guide as you could see you should move to NULL state when you link/unlink an element.

I am wondering is element like output-selector will work for your use case. Probably will be possible to switch between two waylandsink elements.

I not tried this on gst v1.x.

Please refer this for more information is it fit to your use case:

https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-output-selector.html

I would recommend you to search in the gstreamer tutorials and documentation are there other options.

Hope this helps.
