Dm368

In the SPRAAI7B document ,They say "When the input source is the preview engine, the maximum input width cannot be greater than 1280
due to the preview engine’s maximum output width restriction of 1280" ,now i am using dm368 ,if i want to use 1080P resolution,but the ipipe(preview engine) can't support width larger than 1280,Is the adanvanced feature can't support on the 1080p resolution because they can't process with ipipe
