Hi,
Configuring to ‘UYVY’ format should work, please check if you can run

$ gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,format=UYVY,width=1280,height=720,framerate=30/1 ! videoconvert ! video/x-raw,format=I420 ! nvvideoncvert ! 'video/x-raw(memory:NVMM),format=I420' ! nvoverlaysink

I just tried it returns a err. btw how do i run with deepstream instead ?

gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,format=UYVY,width=1280,height=720,framerate=30/1 ! videoconvert ! video/x-raw,format=I420 ! nvvideoncvert ! ‘video/x-raw(memory:NVMM),format=I420’ ! nvoverlaysink
WARNING: erroneous pipeline: no element “nvvideoncvert”

i think you have a typo there … after i change to nvvideoconvert it runs. but how do i verify it ??
also how do i use deepstream app to do the same ??

gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,format=UYVY,width=1280,height=720,framerate=30/1 ! videoconvert ! video/x-raw,format=I420 ! nvvideoconvert ! ‘video/x-raw(memory:NVMM),format=I420’ ! nvoverlaysink
Setting pipeline to PAUSED …
Pipeline is live and does not need PREROLL …
Setting pipeline to PLAYING …
New clock: GstSystemClock

after running your command / i can see the camera on the screen.

now the question is that how to do i do the change with deepstream app to be able to send camear video to rstp remote .

thanks

Hi,
You have tried the sample config file in running deepstream-test5:

deepstream_sdk_v4.0.1_jetson\samples\configs\deepstream-app\source1_usb_dec_infer_resnet_int8.txt

Have you tried to run it in deepstream-app?

i tried . similar err . with this config file source1_usb_dec_infer_resnet_int8.txt it can not read the engine file defined model-engine-file=…/…/models/Primary_Detector/resnet10.caffemodel_b30_int8.engine

I got deepstream-test5-app -c configs/deepstream-app/source1_usb_dec_infer_resnet_int8.txt
working. but I have to do below two things

  1. Disable [primary-gie] becuase there is no resnet10 in part of deepstream sdk
    enable=0
    model-engine-file=…/…/models/Primary_Detector/resnet10.

2.I noticed that there are 3 dev node /dev/video0 /dev/video1/ /dev/video2
so in the config file source0 I tried camera-v4l2-dev-node=1 and camera-v4l2-dev-node=2 they both works . but only camera-v4l2-dev-node=0 is failing.

  1. realsense camera provide depth image and rgb image i saw /dev/video2 is RGB image but i dont know how the depth image are create out of /dev/video0 and /dev/video1 . probably realsense sdk do some other processing to create the depth image. if that is the case. how do I plugin the realsense sdk driver into deepstream. should I write a application on top of realsense sdk . so instead deepstream read from /dev/video0 1 2 it read from my application as src into deepstream ?

Thanks,
Terry

Hi,
Please run ‘gst-inspect-1.0 v4l2src’ to get supported formats. It looks like the non-working formats are not supported by gstreamer frameworks. Since DS SDK is based on gstreamer, some device nodes on RealSense cameras may not be opened. A general usecase of USB cameras is to run in YUV422 such as UYVY, YUY2.

sure i will run it tomorrow . but could you tell me where to change the format in the configuration file ?

also if node is not opened as you suggested . Can I read the depth data from realsense application and send it to Deepstream as input ?

Hi,
By default we have the implementations in source group:
https://docs.nvidia.com/metropolis/deepstream/dev-guide/index.html#page/DeepStream_Development_Guide%2Fdeepstream_app_config.3.2.html%23wwpID0E0QB0HA

One possible solution is to add one type(ex: type=6) to support appsrc. In the implementation, you need to convert Z16 into NV12 and create source bin like

appsrc ! video/x-raw,format=NV12 ! nvvideoconvert ! 'video/x-raw(memory:NMM),format=NV12'

deepstream-app is open source and you can customize it into the usecase.
Other users may have other possible solutions to share here.

Hi,
Don’t see Z16 is listed in

format: { (string)RGB16, (string)BGR, (string)RGB, (string)GRAY8, (string)GRAY16_LE, (string)GRAY16_BE, (string)YVU9, (string)YV12, (string)YUY2, (string)YVYU, (string)UYVY, (string)Y42B, (string)Y41B, (string)YUV9, (string)NV12_64Z32, (string)NV24, (string)NV61, (string)NV16, (string)NV21, (string)NV12, (string)I420, (string)BGRA, (string)BGRx, (string)ARGB, (string)xRGB, (string)BGR15, (string)RGB15 }

Please refer to #15 on customizing deepstream-app.

Hi

Could you please explain a bit more.

Is it because realsense does not support z16 format or streamer does not support z16 format?

What it takes to add z16 format support?

Thanks

Hi,
I think gstreamer does not support z16 in v4l2src plugin. But maybe I am wrong since I don’t have experience to sun realsense camera in gstreamer pipeline.

Could you please go to
http://gstreamer-devel.966125.n4.nabble.com/
v4l2src is native gstreamer plugin and gstreamer forum users may have experience in running it with realsense cameras.

Hi

I have a fps question. ./deepstream-test5-app -c configs/deepstream-app/source1_usb_dec_infer_resnet_int8_color_display.txt and i set 1920x1080 30 fps in the conig file.

but the fps only show 11

below is v4l2 dump it shows 1920x1080 can do 30fps… anything wrong ?
