regarding multiple displays

hi all,

I am working on omap4430 (pandaboard)

I am trying to display two different videos on video1 and video2 (using gstv4l2sink).

but i am able to play but not able to see at once.

i tried changing overlay0,1, and 2( /sys/devices/platform/omapdss/overlay*) parameters but no luck.

my trails:

1.able to see framebuffer and video1 once 

2.able to see framebuffer and video2 once 

3.when i play on video2 and after that play video1 its overwriting i am able to see video1 display but otherway is not working.

 

please help me what to change exactly so that i can see all the data on framebuffer,video1 and video2 at a time 

 

thanks,
