Other Parts Discussed in Thread: TVP5146

Hello All,

I followed following link to update kernel on our custom DM6446 board.

http://processors.wiki.ti.com/index.php/Using_the_community_kernel_on_DM6446_with_the_DVSDK

Everything went great and there were no errors but when i tried to test encode demo with DMAI_DEBUG=2

:

Encode demo started.

    This part looks strange to me why display thread creates 3 buffer? and why their physical address doesn't look correct at all? Any idea?
