Facing Problem in Video On Demand (RTSP)

[dineshatit]

hi viewers ,

In Server,we have installed VLC in fedora core 7. And client also vlc player .

1. the server is started using following commands

vlc -vvv -I http --rtsp-host 0.0.0.0:5554

2. the files are uploaded for Video On Demand in web browser using http://x.x.x.x:8080/vlm.html

3.in client side ,the request was rtsp://x.x.x.x:5554/test in vlc N/w stream

the problem in client side is, not received the audio or video . Using wireshark , we have captured the follows

I think the problem is Unsupported Transport , So what would be the problem ?

Note : 1.In Server , broadcasting is working.
2. Server is in Remote.
3. VOD is working on LAN .
4. As i seen in forum that , rtsp won't support TCP . but it support UDP.


please solve the problem what am facing ....................

[yohann.martineau]

did you try to use udp transport instead of tcp?
i think that's the problem.

[bulek]

did you try to use udp transport instead of tcp?
i think that's the problem.

Hi,

how can I set up udp or tcp with vlc as rtsp server ?

Thanks in advance,

regards,

Bulek.

VOD works for me.
I used HTTP interface to configure VOD.
I have started vlc with the following command.
vlc --extraintf http --http-src http/ --http-host localhost:80
make sure that port 80 is not in use.
From the browser I have accessed vlc http inteface using the url http://localhost/vlm.html
In the interface click on the video on demand button
Give any name in the name field : I have given "test"
Select an input file."somefile.avi"
Then click on send button.

Now you can access it from any vlc palyer using rtsp://[serverip]/test

Streaming is not working if the input file is .wmv or file name contains special characters like single quotes ( ' )

I wish to know two things, any input to this will be helpful.
1) whether I can give screen:// as input so that I can capture and send my desktop as VOD.
2) Is it possible to run setup VOD from command line.

Thanks in advance.

Your client is trying to use RTP over TCP through RTSP interleaving. This is the worse possible real-time media transport ever made. VLC does not support this (on the server side). So your client falls back to normal RTP/UDP, which the VLC server accepts.

But then it times out for some reason. Most probably a firewall/NAT problem.
