Gstreamer stop diffusing after 2 hours (Jetson nano 4GB)

leben06 · September 2, 2023, 10:36pm

Hello,
I have an issue with my Jetson Nano, and I can’t figure out where it’s coming from. I’m streaming my webcam feed on Twitch, and it works perfectly fine. However, after about 2 hours, the stream stops abruptly, and I don’t receive any error messages, so I’m not sure where to look to resolve this problem. If anyone has any ideas, they would be greatly appreciated. Thank you!

code:

gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! queue ! nvvidconv ! nvv4l2h264enc ! 'video/x-h264, streamformat=(string)byte-stream, width=1920, height=1080, framerate=30/1' ! h264parse ! flvmux streamable=true name=mux ! rtmpsink location="rtmp://ymq03.contribute.live-video.net/app/TWITCH_KEY" audiotestsrc ! mux.

terminal :

Not sure, but you may try adding a queue before each input of mux:

gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! queue ! nvvidconv ! nvv4l2h264enc ! 'video/x-h264, streamformat=(string)byte-stream, width=1920, height=1080, framerate=30/1' ! h264parse ! queue ! flvmux streamable=true name=mux ! rtmpsink location="rtmp://ymq03.contribute.live-video.net/app/TWITCH_KEY"      audiotestsrc ! queue ! mux.

You may also post the supported modes from your V4L source with:

v4l2-ctl -d0 --list-formats-ext

for better advice.

Thanks for your advice, i will run with the queue for each, and can tell if it works after some hours.

This time, the code ran all day without any issues but eventually stopped the stream in the evening. It seems like the stream stopping is random. I’m thinking that it might be due to the option that if I experience a brief loss of connection with my Wi-Fi, the stream stops, and the bash script terminates. So, it might be necessary to wrap it in a Python script to automatically restart if that is indeed the issue, although I’m not entirely sure. Any thoughts?

Hi,
Please try the command and see if it works well in long-run test:

$ gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! queue ! xvimagesink sync=0

See if camera preview is alive after 12+ or 24+ hour run. This can ensure the camera source is stable and does not trigger the issue.

And we suggest enabled the properties for streaming:
Encoding CSI camera with x264enc codec - #3 by DaneLLL

Honey_Patouceul · September 4, 2023, 7:50pm

First reply to @DaneLLL’s question.
You don’t need videoconvert as your camera provides YUYV 4:2:2 (in most cases this should be YUY2 format with gstreamer, and supported as input of xvimagesink). Pick up your preferred mode from the list you’ve sent in index 0 (YUYV) or index 1 (MJPG) and adjust the following gstreamer pipeline:

# Reading raw YUYV 4:2:2 video:
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=640,height=480,framerate=30/1 ! queue ! xvimagesink

# Or reading MJPG:
gst-launch-1.0 v4l2src device=/dev/video0 ! image/jpeg,format=MJPG,width=640,height=480,framerate=30/1 ! nvv4l2decoder mjpeg=1 ! queue ! nvvidconv ! xvimagesink
# Or alternetively (using jpegparse may require disabling sync):
gst-launch-1.0 v4l2src device=/dev/video0 ! image/jpeg,format=MJPG,width=640,height=480,framerate=30/1 ! jpegparse ! nvv4l2decoder mjpeg=1 ! queue ! nvvidconv ! xvimagesink sync=0

With DaneLLL’s command, it runs smoothly for 24 hours.

Additionally, I implemented the idea I had in mind by wrapping the bash script with Python, and it seems to be working for now. The stream has already interrupted and resumed on its own :

import subprocess
import time

def is_network_connected():
    try:
        subprocess.check_output(["ping", "-c", "1", "google.com"])
        return True
    except subprocess.CalledProcessError:
        return False

def execute_command():
    command = "gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! queue ! nvvidconv ! nvv4l2h264enc ! 'video/x-h264, streamformat=(string)byte-stream, width=1920, height=1080, framerate=30/1' ! h264parse ! queue ! flvmux streamable=true name=mux ! rtmpsink location='rtmp://ymq03.contribute.live-video.net/app/TWITCH_KEY' audiotestsrc ! queue ! mux."
    subprocess.call(command, shell=True)

def main():
    while True:
        if is_network_connected():
            print("Network is connected. Executing command...")
            execute_command()
        else:
            print("Network is not connected. Waiting for reconnection...")
        
        time.sleep(10)

if __name__ == "__main__":
    main()

I execute this script with nohup so that it continues to run even after I’ve terminated my SSH connection.

Furthermore, Honey_Patouceul, your second suggestion would be to change the command to:

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=1280,height=720,framerate=30/1 ! queue ! h264parse ! queue ! flvmux streamable=true name=mux ! rtmpsink location='rtmp://ymq03.contribute.live-video.net/app/Twitch_Key' audiotestsrc ! queue ! mux.

Is that correct?

No, video/x-raw is not video/x-h264. For encoding into h264, you would use:

# Use nvvidconv for converting into NV12 format into NVMM memory as expected by nvv4l2h264enc;
gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=1280,height=720,framerate=30/1 ! nvvidconv ! nvv4l2h264enc ! queue ! h264parse ! queue ! flvmux streamable=true name=mux ! rtmpsink location='rtmp://ymq03.contribute.live-video.net/app/TWITCH_KEY'      audiotestsrc ! queue ! mux.
