Hi,

I got a couple of cameras with the HI3518E chip (HI3518E_50H10L_S39 according to Onvifer, cannot find this in the activex UI though). They are running firmware V4.02.R12.00006510.10010.1407, built 2015-03-17 09:44:44.


Overall they seem to work good, but one problem I have is that I can only have one RTSP client connected. Connecting a second RTSP client will handshake properly (OPTIONS, DESCRIBE, SETUP, PLAY all gets 200OK with identical results on both first and second connection), but after 200OK on PLAY, no data is sent, the camera just idles silent.
Connecting to the low-quality sub-stream instead does work. And the ActiveX UI which has it's own video transport over port 34567 works. But not RTSP.


Connecting multiple clients works fine on my TOP201 cameras (identical firmware version V4.02.R12.00006510.10010.1407, non-identical build date 2014-10-23 16:54:02. does not report any model but I *think* HI3518C?), so I kind of expected it to work fine here with these ones as well..


Any ideas? Is this expected behaviour, or can it be fixed?

Regards

I have the same firmware and it is currently streaming 2 RTSP sessions, a web session and an ONVIF session
