video streaming from a LAN camera

chamson · Postby **chamson** » 28 Mar 2006 10:33

I am trying to view a video broadcasted from a LAN camera (D-link DCS-5300W) on vlc media player and without succes.
Can any body help me by telling me how to proceed or by giving me tips.

It would be smart to know the address and how it was being streamed and in what format in order for you to try to trouble shoot your problem.

the adress is usless for you because the camera is connected to local area network and you don't have access to this network but still here it is http://10.13.96.22
the format of the video is MPEG-4
but I don't know what you meen by "how it was being streamed " can you give an example please

I don't want to view you cam!

But it is useful to you.

Assuming that the source (cam) is mpeg and the transcoding was successful and the result has been checked. All though you did say connected to the LAN, I did not try to look it up and you did not say how, so I assumed VLC as the server.

All you should need to do is open VLC and enter http://address:port Considering it is local all you should really need is to enter the http://:port

http:// in this case is the method or how it is being streamed.

to be more precise i wan to broadcast the video of the camera through VLC Media Player on a server (windows server 2003).

I see! Well, I will finish my statement then.

VLC uses the capture device Direct Show driver output and is setup in File -> Open capture device. Once you have verified that the cam is working try transcoding so that you get a feel for formats and containers, file size and bit rate versus quality. You should always try to create compatible forms so that other players can play the files. This should give you most of the information for streaming. Except, be aware that most cams are raw video and audio out and this limits the transcode and stream functions. If you have problems or questions regarding the cams output format and or getting it to work with VLC I would recommend Graph Edit to verify the Direct Show drivers.

i can't use direct show because the camera broadcasts it's video on a navigator. The camera never stops broadcasting unless i turn it off.

If the cam does not have Direct Show drivers it can not be used with VLC as a server. This does not mean that VLC won't work as a client.

but i wan't to use it as a client and not as a server

i thought that i was close but i was wrong
and when i opened the message box i got this...

I don't know anything about sockets and I thing that it is the main probleme
so if any one has an don't be I open to any proposition
thanks

Im doin a similar thing with a Dlink DCS 2120
not sure if your model supports it but try opening a new stream in vlc with the MRL rtsp://<IP Address>/<LIVE STREAM NAME>.sdp or similar
that worked for me
BTW if you figure out how to access the RGB raw data in any programming language could you let me know.
I can't really figure out hoe to do this in VB.NET I can play the stream fine but can't access the data
