Hi Jerry，
thanks for your response. Now i can use follow commad to preview isp outputimage
gst-launch-1.0 v4l2src device=/dev/video0 ! “video/x-raw,format=UYVY,width=1920,height=1080,framerate=30/1” ! nvvidconv ! “video/x-raw(memory:NVMM),format=NV12” ! nvoverlaysink sync=false
could you please have a quick try with nvv4l2camerasrc plugin,
for example, $ gst-launch-1.0 nvv4l2camerasrc device=/dev/video1 ! 'video/x-raw(memory:NVMM), format=(string)UYVY, width=(int)1920, height=(int)1080, framerate=(fraction)30/1, interlace-mode=progressive' ! nvvidconv ! nv3dsink -e
Hi jerry，
I try with nvv4l2camerasrc, no image show, here is log.

I run gst-launch-1.0 v4l2src device=/dev/video0 ! “video/x-raw,format=UYVY,width=1920,height=1080,framerate=30/1” ! nvvidconv ! “video/x-raw(memory:NVMM),format=NV12” ! nvoverlaysink sync=false , image can show., but image looks abnormal
here’s another test approach.
you may dump the YUV frames as following. $ v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=UYVY --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=test.yuv
and… use the 3rdparty tool, such as 7yuv to open this capture image,
there’s options to select different color formats to display the capture frames.
please check you’re able to select one of the YUV formats to output normal images.
Hi jerry,
i do as what you said, but image looks also abnormal nomatter which yuv format is selected. Is it possible to suspect that there is a problem with the isp output image itself？
per your capture results in comment #6, I cannot tell there’s image contour, or it’s complete green.
how about the hex values, do they looks like pixel values or something else?
It can be seen from the comparison that the Y component is correct, UV componet is not correct. Do you know what factors will cause UV component abnormality？
