mcvip - how to escape interlace

Other Parts Discussed in Thread: TVP5158

Hi All,

I have SDK 4, with MCVIP from SDK 3.  DM365(8) + TVP5158.

Data flow is following TVP5158->MCVIP->Resizer->H264Encoder->Other customers (Network, Storages, etc.)

All works fine DM365 encodes four CIF resolution streams, DM368 encodes four D1 streams. We're encoding only video yet, without audio.

So question is following: how to escape interlace? from TVP we have BT656 video - it is interlaced, we're trying to force IVIDEO_INTERLACED parameter for the encoder, but it is not helps. Any ideas, suggestions - are welcome.

PS: for CIF resolution we have workaround: we're capturing D1 image, but then resize it to CIF - so no interlace in that case.

    Additional information - on DM368DVR-UD1 sample hardware I see on monitor (connected to the box) not interlaced video, but when I try to execute mcvip_test.out and watching encoded video - I see interlace. As I understand interlace added somewhere in encoder?

    My encoder parameters dump is:

    All, TVP5158 and DM365(8) - doesn't support deinterlace.
