Hi

I've got an DVR6116CW-H video recorder, it can send video using RTSP,

If I get video streaming using avplay I can see the camera flawlessly

avplay -f rtsp -rtsp_transport tcp -i "rtsp://user:*****@10.0.1.67:554/PSIA/streaming/channels/401"
The output is:

Input #0, rtsp, from 'rtsp://user:*******@10.0.1.67:554/PSIA/streaming/channels/401':
Metadata:

I'm using zm 1.29.0

The set up for the camera is

Name Camera1
Server None
Tipo Origen Ffmpeg
FunciĆ³n Monitor
Habilitado Yes
Linked Monitors
Analysis FPS 21
Maximos FPS (?) 21
Alarm Maximum FPS (?) 21
Reference Image Blend %ge 12%
AlmRefImageBlendPct 25%
Triggers

Source Path rtsp://user:*******@10.0.1.67:554/PSIA/streaming/channels/401
Remote Method RTP/RTSP
Options (?)
Target colorspace Color 24 bits
Captura Ancho (pixels) 960
Captura Alto (pixels) 576
Preserve Aspect Ratio
OrientaciĆ³n Normal
Deinterlacing Disabled

But I only can see a blue rectangle when I try to watch the image from the camera.

I've tried all combinations RTSP/Unicast RTSP/multicast, etc.. I have added ?tcp at the end... no joy

netstats shows that there is a TCP connection open
tcp 0 1 10.10.0.71:34924 10.0.1.67:554 SYN_SENT 6197/zmc

I have run out of ideas :-), any suggestion will be welcome

Yes, but I was unable to make it work. I got this error each few seconds

Can you just open the rstp port given in url or is there more ports needed? UDP or TCP? Thanks
