[EZSDK]USE capture_encode to capture 1004x1004 VIDEO ,how to set HDMI output as 1004?

HI,everybody.

I use capture encode demo  to capture 1004x1004 video(50p),i modify the resolution of "1080p" set H as 1004 and W as 1024 ,then use

 ./capture_encode_a8host_debug.xv5t -o sample.264 -m 1080p -f 60 -b 8000000 -d 0 -n 1000

But when display on the LCD screen,just have half of full size . In HDMI USER GUIDE ,It just support four display mode :1080p30 1080p60 720p30 720p60.

How to set the HDMI output resolution as 1024X1004?
