It occures a error when I running deepstream by kubernetes（kubernetes 1.20.9）.
It can not pull rtsp stream at first, and then v4l2allocator errors published. Finaly, the deepstream run successfully.

How to solved this issue?

Thanky you very much.

Could you explain the steps in detail?

4

Certainly.
We deploy deepstream-6.2 through kubernetes 1.20.9.

When deepstream-6.2 started, it can not pull rtsp stream at first, and then v4l2allocator errors printed. Finaly, the deepstream run successfully.
The log is as following.

I mean you can attach the detaileds for each step you take.

  1. How do you deploy the DeepStream by kubernetes?
  2. What’s your command to run deepstream?
  3. What’s the config file in your command?

Are there any other questions after this?

I used python3 to start deepstream-app, but the process only use one core when it boot.

        self.sub = subprocess.Popen(
            'deepstream-app -c %s -t 1' %cfg,
            shell = True, stdin = subprocess.PIPE, 
            #stdout = subprocess.PIPE, stderr = subprocess.PIPE,
            stdout = subprocess.PIPE, stderr = subprocess.STDOUT,
            #env={'LD_PRELOAD': '/opt/nvidia/deepstream/deepstream-6.0/models/preprocessvehicel/build/libmyplugins.so', 
            env = popen_env_str,
            cwd = '/opt/nvidia/deepstream/ds-app/ds-cfg')

So, the deepstream could not start successfully.

But these code can run success on gax xavier, the jpack is also 5.1.2.
Why did these happend?
Could you give me a hint?

It seems like a rtsp source issue from your log.

Can you confirm the following points?

  1. the same DeepStream version
  2. the same Jetpack version
  3. the same rtsp source
  4. the same DeepStream command and config file

I test rtsp source and verify it is ok.
I found when deepstream start, it only take up one cpu core, I think this occure deepstream did not have enough cpu resource and then it pull rtsp error.

You can try to run the DeepStream command after the machine is fully booted.
If it can work normally, it means that some of your boot configuration has a problem, please check that yourself.
