I need put some picture or text over playing video on hdmi kmssink, mx8mq does not support gstreamer "overlaysink", then which way is possible to implement this feature? Thanks.

root@imx8mqevk:~# gst-inspect-1.0 overlaysink
No such element or plugin 'overlaysink'

MX8MQ does not have GPU 2D, and already double checked i.MX_Linux_User's_Guide.pdf

Hi Weide,

The overlaysink plugin is based on the GPU. It provides two main functions for video rendering:

• Video Overlay: composites multiple video playbacks into the same display.

• Multiple Display: shows videos to multiple displays, up to four displays.”

If your board does not have gpu it can not complete the task.

Hi Alfred,

MX8MQ has GPU, but does not have 2D, only supports 3D. possiable to use overlaysink?

I am using testoverlay overy playing video at the bottom of screen, but the quality of 720p movie is not good, CPU is too busy. Without testoverlay,720p movie is playing well.

Thanks for your help!
