for imx8mq, you can use the command like

"gplay-1.0 /unit_tests/4K_AVC_24fps_22Mbps_AACLC_44.1Khz_2ch_Honey_bee.mp4 --video-sink="kmssink driver-name=imx-dcss" & gplay-1.0 /unit_tests/bbb_sunflower_1080p_30fps_normal.mp4
"

and imx8mq supports dual UI as default, for imx8mp, you can use mouse to enable the second display, then on the second display, you can use the gstreamer command or click the menu on the top left corner to playback

for dual clone mode, pls refer to the suggestion as below:

The main work is from weston user space, for imx8mp lvds and hdmi, there are two CRTCs("users can make the difference between guaranteed synchronized monitor timings (shared-CRTC clone mode) and not -- asynchronous clone mode (independent CRTCs).").

we don't have any sample code for customer, but customer can try this suggestion

Hi NXP 

So about the imx8mp dual display.

Nxp cannot provide the SOP porting and source code for display same content on dual display in imx8mp, right?

We need to response my customer.
