frequent disconnections in the media stream : AXIS P5655-E (PTZ Dome Network Camera)

[SihyunPark01]

Good afternoon.
We are experiencing frequent disconnections in the media stream in the camera AXIS P5655-E due to the following errors.

Error code : 80040201
The media stream connection was lost. This issue may be caused by changes made on the AXIS device.

(Programming error messages :
Exception not handled.
System.Runtime.InteropServices.COMException: 'An error occurred while calling a COM component, resulting in HRESULT E_FAIL being returned.'
)

Could your software engineers identify the issue and provide an explanation?
Additionally, could you please update the component in the programming to solve this problem as soon as possible?

Hopefully, I can also get your feedback via e-mail ([email protected]) if possible.
Thank you.

Answers to your questions will most often come from the community, from developers like yourself. You will, from time to time, find that Axis employees answers some of the questions, but this is not a guarantee. Think of the discussion forum as a complement to other support channels, not a replacement to any of them.

If your question remains unanswered for a period of time, please revisit it to see whether it can be improved by following the guidelines listed in Axis support guidelines.

Hi @SihyunPark01 ,
I have tested the latest example from AXIS Media Control SDK, 64-bit, version 7.52 without any error

Used the following device from AXIS Virtual Loan Tool:
AXIS P5655-E PTZ Dome Network Camera
AXIS OS version 11.11.73

Here are some common issues and troubleshooting steps you can take:

Network Issues

1. Bandwidth: Ensure that your network has sufficient bandwidth to support the camera's video stream. High-resolution video requires more bandwidth.
2. Network Traffic: Check for high traffic on your network which might be causing congestion and resulting in disconnections.
3. Network Configuration: Ensure that your network configuration (switches, routers, firewalls) supports the camera's traffic. Quality of Service (QoS) settings can prioritize video traffic.

Power Supply

1. Power Stability: Ensure that the camera is receiving a stable power supply. Unstable or insufficient power can cause the camera to reboot or disconnect.
2. Power Over Ethernet (PoE): If using PoE, make sure the switch or injector provides adequate power.

Camera Settings

1. Firmware: Check if the camera's Axis OS is up to date. Update to the latest Axis OS if necessary. I have used the latest AXIS OS version 11.11.73
2. Stream Settings: Adjust the camera's stream settings (resolution, frame rate, bit rate) to match your network's capacity.

Multicast vs. Unicast:

Configure the camera to use multicast streaming if your network supports it, as this can reduce network load.

Troubleshooting Steps

• Restart: Power cycle the camera and networking equipment.
• Isolate the Camera: Connect the camera directly to a different network or switch to see if the issue persists.
• Replace Cables: Try using different network cables to rule out faulty cabling.
• Check Connections: Ensure all network connections are secure and properly seated.

Hi @vivekatoffice ,
First of all, thanks for your quick feedback.
Let me describe my current problem more specifically.
(I've also tested the latest one from AXIS Media Control SDK, 64-bit, version 7.52, though.)

I am using the Axis SDK for a project that requires frequent connections and disconnections due to the large number of computers and cameras involved. However, when I use a while loop to repeatedly connect and disconnect the cameras, an error occurs after about an hour.

Here are the error messages and source code.

Error code : 80040201
The media stream connection was lost. This issue may be caused by changes made on the AXIS device.

(Programming error messages :
Unhandled Exception.
System.Runtime.InteropServices.COMException: 'An error occurred while calling a COM component, resulting in HRESULT E_FAIL being returned.'
)

Hopefully I can get your feedback ASAP.
Thanks a lot.

Hi @SihyunPark01 ,
You may need to provide a small sample(GitHub repository) based on our AXIS Media Control SDK samples where the issue is reproducible.

[SihyunPark01]

Good morning @vivekatoffice ,
Let me upload the sample(GitHub repository) that my issue is reproducible.

https://github.com/SihyunPark01/Sample_Axis_MedioControlSDK.git

I'm waiting for your quick reply.
Thanks.

Hi @SihyunPark01 ,
Thank you for the sample code. I just increased the Delay to 5000 as I am working with the remote cameras from
AXIS Virtual Loan Tool

I kept it running for 1 hour without hitting the exception 😞

[SihyunPark01]

@vivekatoffice , Thanks for your quick reply.
Then.. you mean with a Delay of 1000, it can't keep running without hitting the exception, so we have to set the Delay to at least 5000 ??????

Could you give it a try? It also depends on the network conditions and how long it takes to start playing the stream.
