Hello everyone, I've the following trouble:

I need to show the stream from an Axis M7001 Video Encoder, that allows 20 max views.

If I open from 4 different computers the page with the MediaElement declared as shown below:

void Video_Opened(System.Object sender, System.EventArgs e)
{
MediaElement1.Source = new Uri ("axrtsphttp://192.168.1.101/axis-media/media.amp", UriKind.Absolute);
}

and from one of those I rapidly change page from that to another and back, when I reach the 20 times allowed the stream isn't available anymore.

The question is:

If I add this:

void Video_Closed(System.Object sender, System.EventArgs e)
{
MediaElement1.Source = null;
}

Is enough to free the MediaElement1.Source every time I go away from the viedo page? If not what could I do?

Bye
Ric

Hi Ric,

How are you calling your Video_Opened function? Each time it is called, it will create a connection to the Axis server. Can you not keep track of the 'Uri ("axrtsphttp://192.168.1.101/axis-media/media.amp", UriKind.Absolute)' object so that you do continually make new connections to the Axis server? Are you already doing that?

At the moment I open a new connection every time I open the Video page. But I don't think the problem i due to this calling. The video server is limited to 20 views and even if I change the way of calling that when I'll rech the 20 views The stream will stop.

In my opinion I think the solution is to Close the video stream every time I close the page, in this way I think the number of views will remain always 4.

Could you help me?

Thanks,
Ric

Hi Ric,

Often times with http connections they are held open for a while, just in case the client reconnects to the server again. By setting MediaElement1.Source = null you will not send a command to the http server to shut down the connection.

The only thing I can think of is trying the stop method on the media player, this.MediaPlayer1.Stop(). If that doesn't work, I would look at the Axis server and see if there are any timeouts that you can reduce so that it closes the video connection quicker once a client is no longer receiving video.

I tried to use the Stop() method, but without using this before my object, like this:

MediaElement1.Stop();

It doesn't work and it generate an exception, is this caused something wrong in the code?

In iX 2.0 on a PC the stop function works. What version of iX are you using? In iX 2.0 the media player's default name is MediaPlayer1.

Currently I'm using the 1.31 version. I'll check as soon as possible if the 2.0 version will fix this problem.

Thank you,
Ric
