ST VD56G3 Captured Image Overlapping

[mickey_intero]

Hi 

I am using ST VD56G3 camera to capture .raw image from NXP IMX8m embedded board. I was able to capture the raw file using the following command.

gst-launch-1.0 -e v4l2src device=/dev/video2 ! "video/x-raw, format=NV12, width=1120, height=1360, framerate=30/1" ! filesink location=video01.raw

However, captured images in raw file are overlapping. See the screenshot. There should be only one smoke detector in the image but it shows two smoke detectors. Please advise me.

Kind regards,

Mickey

Hi @mickey_intero,

We often observe mirror artefact when there is a mismatch in width / height between the captured video and the tool that display the video. 

For example, I am able to reproduce your behavior when displaying the video with this line command:

gst-launch-1.0 filesrc location=video1.raw ! videoparse width=2240 height=680 format=nv12  framerate=30/1 ! videoconvert ! autovideosink

Can you make sure that your display tool is correctly set to 1120x1360 pls.

Best regards,

Jean
