Nvv4l2camerasrc green lines in image (SEE3CAM CU135 USB3.0)


Using the following camera pipeline -

export GST_DEBUG=2
gst-launch-1.0 -e -v \
    nvv4l2camerasrc device=/dev/video0 \
    ! "video/x-raw(memory:NVMM),format=UYVY,width=3840,height=2160,framerate=15/1" \
    ! nvvidconv ! "video/x-raw(memory:NVMM),format=I420,width=3840,height=2160,framerate=15/1" \
    ! nvjpegenc quality=100 ! multifilesink location="/home/dlw/tmp/img%03d.jpg" \

The first 10 or so images have this noise present and then it fades out and I get normal images.

Using a similar pipeline with v4l2src->nvvidconv doesn’t result in this noise.

# R32 (release), REVISION: 4.3, GCID: 21589087, BOARD: t210ref, EABI: aarch64, DATE: Fri Jun 26 04:38:25 UTC 2020

I am using gstreamer 1.14.5

In addition, when I increase the camera resolution to 13MP (4208x3120), I get a corrupted image with a Venetian blind effect -


Running the same pipeline at 13MP with v4l2src instead results in a normal image.

Are you able to check r32.6.1 to clarify the problem?
