Streaming video to VLC via RTSP

Robotics & Edge Computing Jetson & Embedded Systems Jetson Xavier NX

Hi, I try your suggestion and the multicast also.
It only works in the same Jetson.
When I try to open the sdp file using another board or PC, it didn’t works.

I try to change the cv2.VideoCapture(0) to:

gst_cap = “v4l2src device=/dev/video0 ! video/x-raw, format=(string)YUY2, width=(int)640, height=(int)480, framerate=(fraction)30/1 ! nvvidconv ! video/x-raw(memory:NVMM), format=(string)NV12 ! nvvidconv ! video/x-raw, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink”
cap = cv2.VideoCapture(gst_cap, cv2.CAP_GSTREAMER)

is this correct for usb webcam?
Thank you

The complete python:

import cv2

gst_cap = “v4l2src device=/dev/video0 ! video/x-raw, format=(string)YUY2, width=(int)640, height=(int)480, framerate=(fraction)30/1 ! nvvidconv ! video/x-raw(memory:NVMM), format=(string)NV12 ! nvvidconv ! video/x-raw, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink”

cap = cv2.VideoCapture(gst_cap, cv2.CAP_GSTREAMER)

gst_out = “appsrc ! video/x-raw, format=BGR, pixel-aspect-ratio=1/1 ! queue ! videoconvert ! video/x-raw, format=BGRx ! nvvidconv ! nvv4l2h264enc insert-vui=1 ! video/x-h264, stream-format=byte-stream, alignment=au ! h264parse ! video/x-h264, stream-format=byte-stream ! rtph264pay pt=96 config-interval=1 ! application/x-rtp, media=video, encoding-name=H264 ! udpsink host=224.1.1.1 port=5000 auto-multicast=true”

out = cv2.VideoWriter(gst_out, cv2.CAP_GSTREAMER, 0, 20, (640, 480))
if not out.isOpened() :
print(“Writer failed”)
exit()
print(‘Writer opened’)

while True:
ret,frame = cap.read()

if not ret:
    break
#cv2.imshow("Image", frame)
out.write(frame)
cv2.waitKey(5)

out.release()
cap.release()

The sdp file:

c=IN IP4 224.1.1.1
m=video 5000 RTP/AVP 96
a=rtpmap:96 H264/90000

It works in the same board only.
