I have Kodak PIXPRO SP360 4k camera connected to the Jetson Nano or TX2 via USB cable.

I want to be able to see that video over browser, either with RTSP stream, Webrtc or something else. It doesn't matter how it works in terms of technology, as long as it works. So if you have any ideas or suggestions be free to share them.

I'm currently trying to run the basic setup. 

./test-launch "nvarguscamerasrc ! video/x-raw(memory:NVMM), format=NV12, width=1920, height=1080, framerate=30/1 ! nvvidconv ! video/x-raw, width=640, height=480, format=NV12, framerate=30/1 ! omxh265enc ! rtph265pay name=pay0 pt=96 config-interval=1"

and

gst-launch-1.0 rtspsrc location=rtsp://127.0.0.1:8554/test ! queue ! decodebin ! videoconvert ! xvimagesink

and I'm getting the error saying 

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Progress: (open) Opening Stream

I have also tried an option that worked for me on PC but I can't get it to work on Jetson. The setup goes as follows.

Download Streameye from https://github.com/ccrisan/streameye and run:

netcat -l 8700 | ./streameye -p 1337

To send the webcam stream I run:

gst-launch-1.0 v4l2src device=/dev/video0 ! decodebin ! videoconvert ! videoscale ! videorate ! jpegenc quality=30 ! tcpclientsink host=127.0.0.1 port=8700

After this I get:

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Internal data stream error.

Output of this command for my camera is:

run your pipe with -v like this and show me result:

gst-launch-1.0 v4l2src device=/dev/video0 ! decodebin ! videoconvert ! videoscale ! videorate ! jpegenc quality=30 ! tcpclientsink host=127.0.0.1 port=8700 -v

  • Run with -v: add -v end of your pipeline, then run it. – Babak Abgh Nov 29 '19 at 09:52
  • It has -v at the end, and it returns this. I managet to run it with streameye but it says that jpeg is too large. I used this pipeline $ gst-launch-1.0 v4l2src device=/dev/video1 io-mode=2 ! image/jpeg,width=1280,height=720,framerate=30/1 ! nvjpegdec ! video/x-raw ! xvimagesink Also I figured out that that solution won't work for me, so I need to use gst-rtsp-server. – Milos Milunovic Nov 29 '19 at 13:12
  • if you want send rtp you can use this:gst-launch-1.0 v4l2src device=/dev/video0 ! rtpmjpegpay ! udpsink port=2000 host=127.0.0.1. your src ( v4l2src produce jpeg you don't have to convert to jpeg) – Babak Abgh Nov 29 '19 at 13:46
  • My video is 4k, 3840x2160. When I try to run, firstly I get: no element rtmpjpegpay. When I delete that part I get: WARNING: from element /GstPipeline:pipeline0/GstUDPSink:udpsink0: Attempting to send a UDP packets larger than maximum size (1554753 > 65507) Additional debug info: gstmultiudpsink.c(722): gst_multiudpsink_send_messages (): /GstPipeline:pipeline0/GstUDPSink:udpsink0: Reason: Error sending message: Message too long – Milos Milunovic Dec 02 '19 at 09:15
  • excuse me, gst-launch-1.0 v4l2src device=/dev/video0 ! rtpjpegpay ! udpsink port=2000 host=127.0.0.1 – Babak Abgh Dec 02 '19 at 16:48

If you want to stream it, the simplest way will be to use gst-rtsp-launch which is part of GStreamer prebuild binaries:

gst-rtsp-launch '( v4l2src device=/dev/video0 ! videoconvert ! queue ! x264enc tune="zerolatency" byte-stream=true bitrate=10000 ! rtph264pay name=pay0 pt=96 )'

Later on you can tune codec, bitrate, but for me this is enough (playable in VLC - rtsp://127.0.0.1:8554/test)
