Exception when using h265 encoding

[simonebarattin]

Hello,
I work for a company that uses your cameras for industrial applications. We are developing a streaming application in C# using your SDK and with Axis cameras. I followed the example code in the samples folder of the SDK. Everything works fine when showing the live and while recording, but sometimes when trying to play back the recordings an exception is thrown and the application crashes. From the windows event logger I found that the exception is thrown by the AxH265DecX64.dll, which I assume performs the decoding of h265 encoded videos. I noticed that before that happens the video I am trying to play seems to not start right away.
Do you know how I can solve this problem? Is there a way to handle the exception?
The streaming profile uses h265 encoding and also in the program I am using the same format to record the video.
The problem occurs also with h264, but not if I use MJPEG, which I cannot use for the limited bandwidth.

I found this post that explains what seems to be the same problem, but no answer was given: https://github.com/orgs/AxisCommunications/discussions/617

Here's the crash event

Thank you in advance.

Hi @simonebarattin ,
I tried testing the latest AXISMediaControlSDK_X64_7_52 with AXIS Q1715 Block Camera (AXIS OS version 11.11.73) using the H.265 video feed for more than 2 hours without any issues.

Make sure that "AxisH265DecoderSetupX64" is installed on the system where you are facing the issues.

Not sure if this can be a problem regarding the decoder licenses:

Could you please let me know which camera model and Axis OS version you're using?

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

Thank you for your fast reply! And apologies if I didn't answer right back.

So I am using 5 AXIS F2135-RE Fisheye Sensors with a AXIS F9114 Main Unit to which I connect in order to stream the live feed and record it. One problem I noticed is that the OS version of the Main unit is the 11.2.68, so that's one thing that surely doesn't help.

I'll try to create a sample code where the problem can be recreated.
Thank you!
