Leopard imaging IMX 728 camera with jetson AGX xavier pinky purple stripes

Hi ,
When I try to directly connect the imx-728 camera with jetson agx xavier , it works properly. But now we have a custom chip inbetween which converts the csi2 (dphy) to base-t1. The connection is as follows , imx-728 camera <==> custom chip master dphy-Rx <==> base-t1 cable <==> custom chip slave dphy-tx <==> jetson agx xavier

In this setup it produces pinky purple video stream as shown below, anyone has any clue why is this happening? How can I rectify this issue?

I have the drivers loaded as suggested by leopard imaging.

Try dump the raw image by v4l2-ctl to confirm the output source from custom slave chip.

Thanks

v4l2-ctl --set-fmt-video=width=3856,height=2176,pixelformat=RG10 --set-ctrl bypass_mode=0  --stream-mmap --stream-count=100 --stream-to=/home/axonne/imx728.raw -d /dev/video0

I am using the above command which is taking too long.

I also do not know the command to convert it to .mp4 using a gstreamer pipeline.

Currently I am using,

gst-launch-1.0 nvarguscamerasrc sensor-mode=0 ! 'video/x-raw(memory:NVMM), width=3856, height=2176, format=(string)NV12, framerate=(fraction)29/1' ! nvvidconv flip-method=2 ! nv3dsink -e

You may capture just one frame instead of 100:

--stream-count=1

If you don’t have a viewer for RG10, you may have a look to : Stream Bayer Data with Gtsreamer - #8 by Honey_Patouceul

You may try:

gst-launch-1.0 nvarguscamerasrc sensor-mode=0 ! 'video/x-raw(memory:NVMM), width=3856, height=2176, format=(string)NV12, framerate=(fraction)29/1' ! nvvidconv flip-method=2 ! nvv4l2h264enc ! queue ! h264parse ! qtmux ! filesink location=test.mp4 -e

Hi,

NVMEDIA: Need to set EMC bandwidth : 2776266 
NVMEDIA: Need to set EMC bandwidth : 2776266

Im getting something like this, It is taking a while for the gst pipeline.

I’d advise to first try at V4L level, for one frame first, then for video at a suitable framerate for your sensor.
Only when these would be ok, you may try Argus and gstreamer.

Sure thank you. Will try and let you know
