Did you try to connect VLC player directly to you IP cams without your RTSP
server?

Hi,

 

The IP Cam has two kinds of resolution. One is 720x576(SD). Another is
1920x1080 (HD). The problem only happens on HD video. It seems that the
problem is relative to the frame size. Isn’t it?

 

BR,

 

Eden

Hi,

This problem may be because you don't have real ip address both client and
server. so you can try with public ip address

Sir.,

 

We are developing an RTSP Relay Server (written according to Live555 Sample
Code) which delivers video from RTSP Servers to RTSP Clients.

 

Figure:

 

IP Cams  <--------------->  Our RTSP Relay Server  <---------------> RTSP
Clients

            rtsp                               rtsp

 

Currently, we use VLC Media Player as our RTSP clients. The problem is that
VLC Media Player can’t display image with a full-black screen when the
network between Our RTSP Relay Server and RTSP Client is connected through a
network Switch. If no Switch there, VLC displays normally. I don’t know why?
(Our own RTSP client does not have this problem.)

 

The frame size of IP Cam is 1920x1080. The frame is transferred with H264
encoded.

 

Do you have any idea about this problem? Thank you so much for any comment
in advance.

 

Sincerely,
