RLC-523WA Stuck on RTSP with h264Preview_01_sub

Chris

Hello everyone,
i am a new owner of a RLC-523WA and impressed of this product and their features.

Since i have chekced some features i have a problem with the RTSP Stream. I monitoring the live stream via VLC (3.0.18) on
Windows 10 and put in the follwing URL:
rtsp://<ip>:554/h264Preview_01_sub

I only noticed it now since i saw an old picture und see that the time is not count up. When i restart the stream i see the new picture but the time is freezed and the picture also.

When i use this URL evrything is fine: rtsp://<ip>:554/h264Preview_01_main

When i use the browser view or the client everything works.

The actually FW ist: v3.1.0.1643_22122310_v1.0.0.30

I don't know which of them causes the Problem.

Any hints?

Regards Chris
