Windows Server Forum / Windows Media Server / October 2008RTSP camera as video source
Hi My Axis camera can provide a RTSP video stream to a limited number of client; in order to reach a bigger number of client I would try to use a streaming server...can Windows media server use my Axis camera as RTSP/MPEG4 video source? Thank you. >Hi > >My Axis camera can provide a RTSP video stream to a limited number of >client; in order to reach a bigger number of client I would try to use a >streaming server...can Windows media server use my Axis camera as >RTSP/MPEG4 video source? Not the server, no - the encoder can. There are specific drivers available from Axis which make the network camera appear as a local device, which windows media encoder can hook up to, and from there it can unicast to the media server which in turn distributes the encoded video data to clients. You need this page for those drivers : http://www.axis.com/techsup/software/capture_driver/index.htm HTH Cheers - Neil ------------------------------------------------ Digital Media MVP : 2004-2007 http://mvp.support.microsoft.com/mvpfaqs Neil Smith [MVP Digital Media] ha scritto: > Not the server, no - the encoder can.

Hi Neil thank you very much for your response. I already know Axis provide a driver I can use with WME, the problem is the driver only works with MJPEG, not MPEG4 (I don't want MJPEG because it needs more bandwidth than MPEG4 and my camera has a low profile ADSL connection to the Internet). I would distribute to a large number of client the RTSP/MPEG4 stream from my Axis camera....how can I do? Is this possible with WM Encoder/Server?

Ah OK that's a much more qualified question - remember I'm not sitting at your PC to know you already had that additional requirement of bandwidth restriction fmor the camera, I'd assumed it was somewhere on a LAN close by. I've not got an Axis setup here, so I'm only aware of the drivers rather than the specific implementation - thx for the detail they only do M-JPEG. I had a feeling there was a MPEG4 option but I also remember they differ in format support depending on device. One other option springs to mind, in that VLC can connect to those cameras (might need to get the SDP file from it first, to connect to the RTSP stream) : see http://www.videolan.org/ and http://wiki.videolan.org/Hardware_Compatibility_list VLC should then be able to send that on to Darwin Streaming Server, so you could optionally run that on the same windows 2003 server and send to Quicktime clients instead - is that a possibility ? I've tried using VLC to transcode and send to WMS, but the server negotiates specifically with WME and sends cookies which VLC can't at present replicate, so that's not an available option to use VLC + WMS.

Sorry, in my first post I didn't explain my requirement very well ;-) > I've not got an Axis setup here, so I'm only aware of the drivers > rather than the specific implementation - thx for the detail they only > do M-JPEG.

I've also tried this option in these days obtaining good result only with MJPEG.... with RTSP/MPEG4 VLC stops transcoding after few seconds; I can't understand why: it plays very well the RTSP stream but when I try to receive RTSP/MPEG4 stream, transcoding it and sending via RTP to Darwin VLC stop working.... I will try more in this direction. Thank you very much for your help! > I've also tried this option in these days obtaining good result only > with MJPEG.... with RTSP/MPEG4 VLC stops transcoding after few seconds; [quoted text clipped - 3 lines] > > Thank you very much for your help! The Axis will stream RTP directly to Darwin. Under the advanced settings, you can directly edit the configuration files. /etc/rtspd/rtspd.conf has a timeout set. Change that to zero. /etc/sysconfig/rtp.conf contains everything else you need. After you set everything, you need to copy /usr/html/mpeg4/media.sdp to the movies directory on Darwin. Delete the line that looks like a=control:rtsp://192.168.1.101:554/mpeg4/1/media.amp from the sdp file. Reboot the camera, and you should be up and running. nobody ha scritto: > The Axis will stream RTP directly to Darwin. yes, I discovered this feature in the meanwhile.... Thank you very much for your help! Hi, There are several free for commercial use, published RTSP DirectShow Source Filters, with full source code in C++. i must admit that it took a LOT of searching to find them! I will tell you about one that I think is the best. Look at the source code for VLC (VideoLAN) and pull out the files: access.c real.c rtsp.c rtsp.h That's all you need. Look at the sample Microsoft has for a source filter for DirectShow and add these files and compile and VIOLA! you have a DirectShow Source Filter that will play any RTSP stream !!! It's easy to compile this in Visual Studio 6.0--it will compile in later versions of VisualStudio but you have to know what you are doing and you have to tweek the code. This makes it easy to use DirectShow to play RTSP streams from ip cameras. I am amazed that nobody has posted this code before. Enjoy |
