Hi:

I use my own camera connet to Nano through MIPI, my camera output 1920*1080@25fps, pix is:

V4L2_PIX_FMT_UYVY and MEDIA_BUS_FMT_UYVY8_2X8

I can use vlc and v4l2-ctl tools get images from /dev/videox, but when I use nvgstcapture-1.0 to preview the images, it’s could not work, and report such error:

GST_ARGUS: Creating output stream
CONSUMER: Waiting until producer is connected…

could you give me some advice, why it not work? Thanks a lot!

Hello,

Thanks for visiting the NVIDIA Developer Forums.
To ensure better visibility and support, I’ve moved your post to the Jetson category where it’s more appropriate

Cheers,
Tom

OK ~ thank you

I’am sure this problem has relationship with pixel format, when use bayyer sensor with RG10, it works well, but YUV can’t work. is libargus plug only support bayyer sensor?

7

that’s correct, it’s mentioned by Camera API Matrix.

BTW,
you may try with nvv4l2camerasrc plugin as an alternative way to test your YUV camera stream via gst pipeline.
for instance, $ gst-launch-1.0 nvv4l2camerasrc device=/dev/video1 ! 'video/x-raw(memory:NVMM),format=UYVY,width=1920,height=1080,framerate=30/1 ! nvvidconv ! xvimagesink

when I enter this command on my Jetson device, it just echo a prompt “>” on command line, not display a screen in my monitor; if I use “export DISPLAY=:1 ;sudo nvgstcapture-1.0 --sensor-id=1” can display the screen；is that any paremeter I need to add?

hello zhangjianbiao,

nvgstcapture-1.0 does not support with YUV cameras.
you should test with nvv4l2camerasrc or v4l2src plugins.

10

gst-launch-1.0 nvv4l2camerasrc device=/dev/video1 ! 'video/x-raw(memory:NVMM),format=UYVY,width=1920,height=1080,framerate=30/1 ! nvvidconv ! xvimagesink

This command not work on my device， it just echo prompt “>” when I enter command, not show screen, is there any paremeter I need to modify ?

11

hello zhangjianbiao,

it seems like an incorrect command-line, please add an ' before video converter.
for instance,
$ gst-launch-1.0 nvv4l2camerasrc device=/dev/video1 ! 'video/x-raw(memory:NVMM),format=UYVY,width=1920,height=1080,framerate=30/1' ! nvvidconv ! xvimagesink

12

it report a warning below:

WARNING: erroneous pipeline: could not parse caps “video/x-raw(memory:NVMM),format=UYVY,width=1920,height=1080,framerate=25/1”

13

gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! ‘video/x-raw(memory:NVMM),format=UYVY,width=1920,height=1080,framerate=25/1’ ! nvvidconv ! xvimagesink

I use this command , it works normal, thank you for your support~

14

gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! ‘video/x-raw(memory:NVMM),format=UYVY,width=1920,height=1080,framerate=25/1’ ! nvvidconv ! xvimagesink

I use this command , it works normal, thanks for your support^_^;

I also have another question, if my camera output UYVY stream, is that means I can’t use ISP which is in orig nano ?

15

hello zhangjianbiao,

please refer to my previous comment in post #7, Jetson ISP support with bayer Raw input contents only.

16

OK, I get it .

today I got another question, when My camera output 3840*2160 format stream，vlc player can’t play full image on screen, Reduce the image to 1/4 of its original size ; when I use command:

gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! ‘video/x-raw(memory:NVMM),format=UYVY,width=3840,height=2160,framerate=25/1’ ! nvvidconv ! xvimagesink

also get the same result, what’s the reason about this?

17

please file a new discussion thread for following up.

OK , I file it right now
