Hello!
Is it possible to set the USB camera to video capture MJPG 4096 x 2160 for high resolution / slow frame rate?
If so, how?
If not, how about NV12, 1920 x 1080?
Else, maybe YUYV 1920 x 1080 ?
Camera is Logitech Brio 4K.
Thanks!
I don’t have such camera, but assuming your brio is /dev/video1, you may try:
# Boost clocks
sudo jetson_clocks
gst-launch-1.0 v4l2src device=/dev/video1 ! 'image/jpeg, width=4096, height=2160, framerate=5/1, format=MJPG' ! jpegdec ! xvimagesink
# If it doesn't work fine, you may different io modes (see: gst-inspect-1.0 v4l2src) such as:
gst-launch-1.0 v4l2src device=/dev/video1 io-mode=2 ! 'image/jpeg, format=MJPG, width=4096, height=2160, framerate=5/1' ! jpegdec ! xvimagesink
For YUYV 4:2:2, you may try:
gst-launch-1.0 v4l2src device=/dev/video1 ! 'video/x-raw, format=YUY2, width=1920, height=1080, framerate=30/1' ! videoconvert ! xvimagesink
For NV12:
gst-launch-1.0 v4l2src device=/dev/video1 ! 'video/x-raw, format=NV12, width=1920, height=1080, framerate=30/1' ! videoconvert ! xvimagesink
# If previous command gives bad scaling, you may also try instead:
gst-launch-1.0 v4l2src device=/dev/video1 ! 'video/x-raw, format=NV12, width=1920, height=1080, framerate=30/1' ! nvvidconv ! nvegltransform ! nveglglessink
Thanks, @Honey_Patouceul ,
gst-launch-1.0 v4l2src device=/dev/video0 ! 'image/jpeg, width=4096, height=2160, framerate=5/1, format=MJPG' ! jpegdec ! xvimagesink
… worked in command line. How do I now do this within detectNet / detectnet-camera? It always seems to revert to 1280 x 720.
Seems for now it expects NV12 from nvarguscamerasrc for onboard camera, or RGB from USB cam.
You may try to adjust the pipeline string created here for a pipeline providing RGB from your camera MJPG stream.
You may first prototype with gst-launch:
gst-launch-1.0 v4l2src device=/dev/video0 ! 'image/jpeg, width=4096, height=2160, framerate=5/1, format=MJPG' ! jpegdec ! 'video/x-raw,format=RGB' ! videoconvert ! appsink
If this works, you would try to make a pipeline string such as :
v4l2src device=/dev/video0 ! image/jpeg,width=4096,height=2160,framerate=5/1,format=MJPG ! jpegdec ! video/x-raw,format=RGB ! videoconvert ! appsink
You may adjust default camera here to 0 instead of -1 for onboard camera.
Probably @dusty_nv would be able to give better advice.
I found where default width and heights are set:
gstCamera.h … Line 81 and 82:
// Default resolution, unless otherwise specified during Create()
static const uint32_t DefaultWidth = 1280;
static const uint32_t DefaultHeight = 720;
Will test it out.
Seems to work.
// Default resolution, unless otherwise specified during Create()
static const uint32_t DefaultWidth = 4096;
static const uint32_t DefaultHeight = 2160;
Edited gstCamera.h as above then:

You seem to use a different pipeline, not using MJPG:
[gstreamer] gstCamera pipeline string:
v4l2src device=/dev/video0 ! video/x-raw, width=(int)4096, height=(int)2160, format=RGB ! videoconvert ! video/x-raw, format=RGB ! videoconvert !appsink name=mysink
Does your brio cam provides 4096x2160 in RGB format ?
Check with
v4l2-ctl -d /dev/video --list-formats-ext
Or check with gst-launch:
gst-launch-1.0 -v v4l2src device=/dev/video0 ! 'video/x-raw, width=(int)4096, height=(int)2160, format=RGB' ! videoconvert ! 'video/x-raw, format=RGB' ! videoconvert ! appsink
If this works, probably v4l2src does the conversion into RGB.
If this doesn’t work you would have to modify the building of the gstreamer pipeline string as suggested in my previous post.
Does not seem to metion RGB:

@Honey_Patouceul detectNet is now working with the Brio, thanks for the pointer to gstCamera. I’m not sure what’s happening in the software, some conversion from MJPG to RGB I think?
Now need to reduce the display size so that it fits on my low res screen again! I’ve created a new thread to address this problem.
Seems the MJPG to RGB conversion is done by V4L, or it may also just resize from a lower resolution…
Last case may have failed because jpegdec is slow if you didn’t boost clocks this time.
Anyway, glad to see it works and you shared.
