Image interference causes continuous recordings

[nigi]

Hi,
I'm using a SV3C 1080P Full HD Poe IP Camera. It's configured with Ffmpeg and rtsp. Everything works fine, but after a while you'll get a disturbed picture (see attachment).
When streaming the same cam with e.g. VLC, I'm getting a excellent picture. So I think this disturbed pictures are caused by Zoneminder. When disabling an re-enabling the cam at Zoneminder, the picture is fine, again. Sometimes for some hours, sometimes for many days.
Has anybody an idea, why I'm getting this fault?

I'm using modetect, but in this case Zoneminder detects many motions per minute. (More then 500 per hour). Is there a way to ignore such a storming? Is there an option to discard an alarm e.g. when there a more then x per Minute?

Thanks!
nigi

(BTW: I'm a real beginner with Zoneminder...)

Search the forum for "ffmpeg" and "streaking" and see what comes up, this happens on some systems.

OK, thanks! Very interesting, I'll follow this thread.
