Hi,

I am fairly new to writting code so appologies if i am missing something silly.

I am trying to create an application using the AxVLCPlugin2 using Visual Studio C# 2010. I have managed to get one video stream (rtsp) working nicely, however i need to have multiple streams at once. I have added multiple "AxVLCPlugin2" from the toolbox however when i try to play more than one i lose another, for example if i set "Video 1" to play it works ok, if i then set "Video 2" to play i lose "Video 1" but "Video 2" is ok.

Heres the code i am using to start 3 streams when a button is clicked:

VideoIcon1.playlist.items.clear();
string Options1 = ":rtsp-caching=250"; //Cache in mS
int StreamNo1 = VideoIcon1.playlist.add("rtsp://192.168.1.153/stream1.sdp", "VideoIcon1", Options1);
VideoIcon1.playlist.playItem(StreamNo1);

VideoIcon2.playlist.items.clear();
string Options2 = ":rtsp-caching=250"; //Cache in mS
int StreamNo2 = VideoIcon2.playlist.add("rtsp://192.168.1.157/stream1.sdp", "VideoIcon2", Options2);
VideoIcon2.playlist.playItem(StreamNo2);

VideoIcon3.playlist.items.clear();
string Options3 = ":rtsp-caching=250"; //Cache in mS
int StreamNo3 = VideoIcon3.playlist.add("rtsp://192.168.1.158/stream1.sdp", "VideoIcon3", Options3);
VideoIcon3.playlist.playItem(StreamNo3);

Does anyone have any ideas where i could be going wrong? Any help would be much appreciated.

Thanks,

I have just noticed that it may not be a problem with my code. I have just tried to play the same network streams using multiple instances "VLC Media Player" and i get the same problem, when i play a video from another IP address the first one stops (even though its playing on another instance of VLC Media Player). The video streams i am looking at come from 4 Input IP encoders and i have just found that if i look at a different stream on each one it works.

For example if i want to see stream number 1 of each encoder this doesn't work, the urls are:

=rtsp://192.168.1.153/stream1.sdp //Encoder 1 - Stream 1
=rtsp://192.168.1.157/stream1.sdp //Encoder 2 - Stream 1
=rtsp://192.168.1.158/stream1.sdp //Encoder 3 - Stream 1

Even though the IP addresses are different it doesn't like the "stream1.sdp" being the same?

If i set up to look at one different video from each encoder it works fine and i can see 3 video's, the urls are now:

=rtsp://192.168.1.153/stream1.sdp //Encoder 1 -Stream 1
=rtsp://192.168.1.157/stream2.sdp //Encoder 2 -Stream 2
=rtsp://192.168.1.158/stream3.sdp //Encoder 3 -Stream 3

However this is no good for me as i need to see all four streams of each encoder, so 12 streams:

=rtsp://192.168.1.153/stream1.sdp
=rtsp://192.168.1.153/stream2.sdp
=rtsp://192.168.1.153/stream3.sdp
=rtsp://192.168.1.157/stream1.sdp
=rtsp://192.168.1.157/stream2.sdp
=rtsp://192.168.1.157/stream3.sdp
=rtsp://192.168.1.158/stream1.sdp
=rtsp://192.168.1.158/stream2.sdp
=rtsp://192.168.1.158/stream3.sdp

Anyone got any suggestions on how to get around this?

Thanks,

Hello, Mark.
Are you using multicast or unicast connection?
May be problem is in same network port number.
What differs in settings between =rtsp://192.168.1.157/stream1.sdp and =rtsp://192.168.1.157/stream2.sdp besides name ofcourse?

I am using an rtsp unicast connection.

The only other thing that differs is the port number, which is port 10000 for stream1.sdp 20000 for stream2.sdp etc.

I have tried setting the port numbers all different though, i.e. 10000 for stream1.sdp on encoder 1 and 10001 for stream1.sdp on encoder 2, but still didn't work.

Thanks,

Mark

Try another video source and play simultaneously in different vlc instances (same source for all instances). Do you have initial problem in this case?
