Interlace display issue with ezsdk display module

Patel Jignesh

Hello TI,

Recently, In our custom board that uses dm814x board we moved from ezsdk_dm814x-evm_5_05_01_04 to ezsdk_dm814x-evm_5_05_02_00 with overlay source code.

We run application that has pipeline like (Capture->(DEI-Port0)->Display). Here DEI port0 will give 720x480 progressive video and Display does re-interlacing for NTSC display. Now this application run without any issue when we are using  ezsdk_dm814x-evm_5_05_01_04 with overlay binary but if we use ezsdk_dm814x-evm_5_05_02_00 with overlay binary then we see some artifacts on NTSC display.

1. Artifacts 1 : Some horizontal lines looks missing in NTSC Display (This observed when steady picture ahead of camera).

2. Artifacts 2: More intelace effect observed on display. Means when we moved object then it show more interlace type of effect on display.

 
Please let us know if there are any change in display controller that can create this issue while moving from ezsdk 5.01 to ezsdk 5.02.


Here are the HDVPSS version for both ezsdk:

ezsdk 5.01 : hdvpss_01_00_01_37 and omx-ti81xx-src_05_02_00_46

ezsdk 5.02 : hdvpss_01_00_01_44 and omx-ti81xx-src_05_02_00_48

Thanks,

    Hi Margarita,

    I saw that release note but I do not see any feature that affect Display module. Also in release note it is just written that few bug fix but not more information.

    Please provide some more information regarding this change. Also let me know with this change in ezsdk if I need to change some things at application layer.

    Thanks,
