Problem in 1080I capture using Capture-Encode demo

Hi ,

I am trying to capture 1080I using OMX capture-encode demo and display on LCD on DM8148 EVM .

I have followed the below TI Forum link for modifying the Capture-Encode Demo to support 1080I (interlaced ) capture ,i have made all the changes that are mentioned in the link .

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/131887.aspx#475028

I am using a DVD player which is providing the Video input 1080I @ 25fps to the DM8148EVM .

The problem is that i am not getting a proper display on LCD ,i see two images ,one extended image getting overlapped with the other normal image .I have done

algEnable.bAlgBypass = 0 which should enable the DEI algorithm ,and i should  get a correct display .

I doubt whether DEI component is deinterlacing ,is there any other way to enable the DEI algorithm ? Is it the Color format issuse? DEI output buffers are in YUV422I format ,should i change it to YUV420SP?

when the application exits ,i get a below error message .
