Help to execute deepstream python sample apps over headless mode

Accelerated Computing Intelligent Video Analytics DeepStream SDK

hi,

(Jetson nano 4gb, jetpack 4.5.1 deepstream 5.1)

i want to execute deepstream python apps on headless mode.

for example, i want to execute

python3 deepstream_test_1_usb.py /dev/video0

and should be able to see the ouput window in headless mode.

i checked metropolis/deepstream/dev-guide/ for deepstream 5.1

i read, Running without an X server

i included following line in the file “dstest1_pgie_config”

[sink2]
enable=0
#Type - 1=FakeSink 2=EglSink 3=File 4=RTSPStreaming
type=4
#1=h264 2=h265
codec=1
#encoder type 0=Hardware 1=Software
enc-type=0
sync=0
bitrate=4000000
#H264 Profile - 0=Baseline 2=Main 4=High
#H265 Profile - 0=Main 1=Main10
profile=0
#set below properties in case of RTSPStreaming
rtsp-port=8554
udp-port=5400

Jetson and my laptop are connected to same network.

now how do i get the output over network stream and see it in vlc?

You need to enable this config by setting “enable=1”

Disable egl sink group and enable rtsp group. The group you post here is the rtsp group.

here is sample config file

i should copy [sink0] and paste it my test3 config file and modify the enable to 0, right?

#8

Yes.
[sink0] enable=0
[sink2]enable=1

What do you mean? deepstream_test_1_usb.py has nothing to do with the deepstream config file.

deepstream config file is for the deepstream-app sample.

deepstream_test_1_usb.py does not need any config file.

Please read the python deepstream document instead. Python Sample Apps Source Details — DeepStream 5.1 Release documentation

#13

If you are not familiar with python gstreamer https://gstreamer.freedesktop.org/bindings/python.html, it is not recommended to use python deepstream. Please use c/c++ deepstream instead.

Even with c/c++ deepstream, you need to have the basic knowledge and development skills of gstreamer before you start with deepstream SDK.
