IN-9420 2K+: Not working with audio disabled

[sherminator]

Hi there,

we have been using Zoneminder 1.36.35 together with Instar cameras for a long time and are very satisfied.
Now we are testing the IN-9420 2K+ (current firmware) for the first time and have the following issue: As long as audio is activated on the camera (Multimedia -> Audio), everything works fine. However, as soon as we disable audio, we no longer get any pictures from the camera. We then find these messages in the logs:

Code: Select all

What can we do about this?

Thanks a lot for your support and many greets

You are going to have to turn on debug logging to get more info.

At the end of the day though, ffmpeg is saying it doesn't support whatever the camera is sending. Maybe you can change that in the camera, or upgrade ffmpeg libraries.
