hello,
Thank you.Now i am able to see the weston screen on both LCD and HDMI monitor.
But when I play video any one of the display will show the video.
I am not getting video simultaneously on both displays.
I am using following command to play video:
target # gst-launch-1.0 playbin uri=file://<path-to-file-name> video-sink=waylandsink

Thank you,
Vijay

Hello,

The video will be displayed on primary display.
Clone is not possible with gstreamer.
There is no property in waylandsink to specify the display.

processors.wiki.ti.com/.../Processor_Linux_SDK_Graphics_and_Display
In the above guide please search for drmclone demo also.
You could try decode display demo also
./viddec3test -s 35:800x480 -- -s 30:1280x720 /path to file/test.264
where 35 and 30 are the connectorID so you must run modetest demo to find these IDs first.
Keep in mind before to run drmclone demo or viddec3test you must stop weston /etc/init.d/weston stop

Hope this helps.
