Get 3840*2160 YUV from v4l2 camera with gstreamer pipeline on Xavier

lilei6 · February 24, 2020, 5:25am

Hello,

There is a logitech “BRIO c1000e 4k” usb camera.
I want to get 4K(3840*2160) YUV from this camera and show by Xavier.
I tried the flowing gstreamer pipeline ,but cannot show normally.

GST_DEBUG=3 gst-launch-1.0 v4l2src device=/dev/video0 ! fakesink -v

Setting pipeline to PAUSED …
Pipeline is live and does not need PREROLL …
Setting pipeline to PLAYING …

When I tried to save a file , also met the sample problem as follows:
gst-launch-1.0 v4l2src ! ‘video/x-raw, width=(int)3840, height=(int)2160’ ! queue ! videoconvert ! omxh265enc ! h265parse ! qtmux ! filesink location=“4k_1.mp4” -e

Could you please show the correct pipeline command to get 4k(3840*2160) YUV video from usb camera?
I’ll be appreciated for any help.

Hi,
Please refer to

Need to configure format,width,height,framerate. Please give it a try.

Hello, DaneLLL

I tried as follows:
v4l2-ctl -d /dev/video0 --list-formats-ext

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=3840,height=2160,framerate=30/1 ! nvvidconv ! ‘video/x-raw(memory:NVMM),format=NV12’ ! nvoverlaysink

as well as “device=/dev/video1”, but it doesn’t work

Hi,
So no modes are printed in running:

v4l2-ctl -d /dev/video0 --list-formats-ext

You should configure the supported mode to gst-launch-1.0 command.

lilei6 · February 24, 2020, 8:43am

no, when runing v4l2-ctl -d /dev/video1 --list-formats-ext

the log is as follows:

Hi,
Looks like 1080p30,YUYV is supported. You may try

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=1920,height=1080,framerate=30/1 ! nvvidconv ! 'video/x-raw(memory:NVMM),format=NV12' ! nvoverlaysink
