VLC VOD server behind a router

[jgg]

Hi,

I have been trying VLM-based VoD for some time in a LAN or in a WAN and everything worked fine. Now I'm trying to get a more realistic testbed where the server is in a WAN and streams to computers in a LAN network. I have been experiencing some problems with this and I have search through this forum to get the answer, but I couldn't find nothing specific nor updated news.

So, when starting VLC to play a VoD stream served from a server behind the router I get these errors:

Code: Select all

[00000424] live555 demux error: SETUP of'video/MPV' failed SETUP: cannot handle response: RTSP/1.0 461 Unsupported transport [00000424] live555 demux error: SETUP of'audio/MPA' failed SETUP: cannot handle response: RTSP/1.0 461 Unsupported transport [00000424] live555 demux error: Nothing to play for rtsp://147.83.47.178:60100/rock_GARBAGE_medium [00000424] live555 demux error: TCP rollover failed, aborting

In the RTSP SETUP messages the Transport field has changed from the LAN-based system, now with the value:

Transport: RTP/AVP/TCP;unicast;interleaved=0-1

I have read that this is caused by the client trying to use RTP over TCP and interleaved RTSP, but I haven't changed VLC options since LAN-based testbed. Can this be caused by having a router/firewall between the server and the client?

I have not opened any port in the router, but I don't know how this affects VLC's behaviour. I have also read (in a thread from 2007) that VLC doesn't support NAT. Is this still true? Can anything be done to use VLC in a testbed like this I'm using?


Thank you all.

First, there is nothing special about running VLC behind a router. The Internet is made of routers.

Second, no VLC RTSP server does not support NAT.

So, could you please tell me how to solve it?


Thank you.

Short of modifying the VLC source code, you cannot solve the problem.

Adding the server ports information in the convenient RTSP messages would suffice?
