Livestream using JPEGLiveSource not showing up

We are trying to develop an application for a camera with the milestone SDK. Currently we are trying to reproduce the MediaLiveViewer sample to later expand it. But currently it runs trough the CameraPicker button code very well, we can pick a camera and the rest of the method gets executed but there it stops. it never goes to JpegLiveSource1LiveNotificationEvent. it is a similar issue to this one: https://developer.milestonesys.com/s/question/0D50O00003EIs1MSAT/

but this topic never got finished

We stripped the code to what we needed but it doesn’t work anymore. In the example though we commented every line out that we don’t need and it still works. Here is the CameraPicker button code

if (_jpegLiveSource != null)
{
     // Close any current displayed JPEG Live Source
     _jpegLiveSource.LiveContentEvent -=           
              JpegLiveSource1LiveNotificationEvent;
     _jpegLiveSource.LiveStatusEvent -= JpegLiveStatusNotificationEvent;
     _jpegLiveSource.Close();
     _jpegLiveSource = null;
     pictureBox1.Image = new Bitmap(1, 1);
}
 
ItemPickerForm form = new ItemPickerForm();
form.KindFilter = Kind.Camera;
form.AutoAccept = true;
form.Init(Configuration.Instance.GetItems());
 
if (form.ShowDialog() == DialogResult.OK)
{
     _selectItem1 = form.SelectedItem;
 
     _jpegLiveSource = new JPEGLiveSource(_selectItem1);
     try
     {
          _jpegLiveSource.LiveModeStart = true;
          _jpegLiveSource.SetKeepAspectRatio(false, false);
          _jpegLiveSource.Width = pictureBox1.Width;
          _jpegLiveSource.Height = pictureBox1.Height;
          _jpegLiveSource.Init();
          _jpegLiveSource.LiveContentEvent += 
                 JpegLiveSource1LiveNotificationEvent;
          _jpegLiveSource.LiveStatusEvent += JpegLiveStatusNotificationEvent;
 
     }
     catch (Exception ex)
     {
          MessageBox.Show("Could not Init:" + ex.Message);
          _jpegLiveSource = null;
      }
}
else
{
     _selectItem1 = null;
}

This is a MIPLibrary project so we have the login screen and we do get connection to the server.

Can anyone help me?

Does the same camera work fine viewed in Smart Client?

Does the MediaLiveViewer sample work for you unmodified?

Did you do the initializations at startup? (http://doc.developer.milestonesys.com/html/index.html?base=reference/architecture/net_library_initialization.html&tree=tree_2.html)

Hi

We made some more references as described in the initialisation and it worked like a charm. Everything works now.

thanks for the help
