How to deinterlace mipi-csi in Orin nano on JetPack 7.2 with Jetson Linux 39.2?

Hi NV team,
I notice that in Jetson_Linux_Release_Notes_r39.2.pdf => 4. Fixed Issues

5451745 De-interlace decode is not supported.

And in video-deinterlacing-with-gstreamer-1-0

The NVIDIA proprietary nvdeinterlace GStreamer-1.0 plugin converts interlaced video frames to progressive video frames. It supports two compute backends:

VIC (Video Image Compositor): Available on the Jetson Orin.

GPU (CUDA-based): Available on the Jetson Orin and Jetson Thor.

But I try following pipe still get interlaced image

DISPLAY=:1 gst-launch-1.0 v4l2src device=/dev/video4 ! \
  'video/x-raw, format=(string)UYVY, width=720, height=480, framerate=30/1' ! \
  rawvideoparse use-sink-caps=false format=uyvy width=720 height=480 framerate=30/1 interlaced=true ! \
  nvvidconv ! \
  'video/x-raw(memory:NVMM), format=(string)NV12' ! \

How can I fix this? Do we suppout deinterlaced?

Doesn’t looks like interlace problem more like alignment problem.

Could you modify the 720 to 736 that have 32 alignment to try.

Thanks
