Linux/AM5728: De-interlacing support in VPE - AM5728

Tool/software: Linux

Hi All

I am working on a custom board based on AM5728. I am using ti-processor-sdk-linux-am57xx-evm-02.00.02.11 SDK right now.

My use case is like this : Camera -> PAL_Decoder -> FPGA -> AM5728

I am able to capture progressive frames from FPGA via VIP. Here FPGA is performing interlaced to progressive conversion and some video processing.

Now i would like to capture even-odd fields from FPGA and perform de-interlacing through VPE.

I am able to capture consecutive fields of 720x288(size of each field = 414720) resolution in UYVY format. i have tried using testvpe and testvpem2m, but not getting progressive frame out of it. I am just getting an upscaled output of size 720x576.

Please let me know how to do this using VPE??

Hello,

Please check this guide:

's_Guide

There is example how to use testvpem2m demo for de-interlacing:

./testvpem2m 480i_clip.nv12 720 240 nv12 dei_480p_clip.yuv 720 480 yuyv 1 3

The blue value should be set to 1.

Hope this helps.
