Convert onvif stream to rtsp address in c#

I am developing a project using c#.in my project i should get the camera stream .So i use onvif to get the stream but i faced a problem .some of my camera can't support onvif and they support RTSP,and i have to use rtsp in my project to :
Here is my onvif code to get the camera stream :
async void StartCameraAfterLogin()
{
//Dooooorbin
await ProcessConnect("http://172.16.0.52/onvif/device_service"
, Properties.Settings.Default.CameraUserName, Properties.Settings.Default.CameraPassword);
}
async Task ProcessConnect(string addr, string name, string pass)
{
//Release();
//ctrlInfo.Content = new ProgressControl();
var account = new System.Net.NetworkCredential(name, pass);
NvtSessionFactory factory = new NvtSessionFactory(account);
////This is syncronouse ui blokking call
//var session = factory.CreateSession(new Uri(addr);
try
{
var session = factory.CreateSession(new Uri(addr));
ss = session;
await FillInfoArea(session);
}
catch (Exception err)
{
Algoa.Utilities.Logger.ToDebug(err);
//ctrlInfo.Content = new ErrorControl(err);
}
}
string profie;
private async Task FillInfoArea(INvtSession session)
{
var profInfo = new ProfieInfoControl();
try
{
var streamData = await profInfo.Init(session);
//sp.Children.Add(profInfo);
profie = profInfo.valueToken.Text;
InitVideoControl(streamData.Item1, streamData.Item4, session.credentials);
//InitPtzControl(session, streamData.Item2, streamData.Item3);
}
catch (Exception err)
{
Algoa.Utilities.Logger.ToDebug(err);
}
//ctrlInfo.Content = sp;
}
private void InitVideoControl(string suri, System.Windows.Size size, System.Net.NetworkCredential networkCredential)
{
InitPlayer(suri, networkCredential, size);
}
public void InitPlayer(string videoUri, NetworkCredential account, System.Windows.Size sz = default(System.Windows.Size))
{
player = new HostedPlayer();
playerDisposable.Add(player);
if (sz != default(System.Windows.Size))
videoBuff = new VideoBuffer((int)sz.Width, (int)sz.Height);
else
{
videoBuff = new VideoBuffer(720, 576);
}
player.SetVideoBuffer(videoBuff);
MediaStreamInfo.Transport transp = MediaStreamInfo.Transport.Udp;
MediaStreamInfo mstrInfo = null;
if (account != null)
{
mstrInfo = new MediaStreamInfo(videoUri, transp, new UserNameToken(account.UserName, account.Password));//, transp, null);
}
else
{
mstrInfo = new MediaStreamInfo(videoUri, transp);
}
playerDisposable.Add(
player.Play(mstrInfo, this)
);
InitPlayback(videoBuff, true);
//{ // playing controls
// btnPause.Click += play;
// btnResume.Click += play;
//}
}
How can i convert my onvif url to rtsp url ?Is there any solution or i should change all part of my code?
I am new in camera stream coding .

I downloaded the OZEKI-SDK
private IIPCamera _camera;
private DrawingImageProvider _imageProvider = new DrawingImageProvider();
private MediaConnector _connector = new MediaConnector();
private VideoViewerWF _videoViewerWF1;
public Form1()
{
InitializeComponent();
// Create video viewer UI control
_videoViewerWF1 = new VideoViewerWF();
_videoViewerWF1.Name = "videoViewerWF1";
_videoViewerWF1.Size = panel1.Size;
panel1.Controls.Add(_videoViewerWF1);
// Bind the camera image to the UI control
_videoViewerWF1.SetImageProvider(_imageProvider);
}
// Connect camera video channel to image provider and start
private void connectBtn_Click(object sender, EventArgs e)
{
_camera = IPCameraFactory.GetCamera("rtsp://192.168.113.150:554/ufirststream", "root", "pass");
_connector.Connect(_camera.VideoChannel, _imageProvider);
_camera.Start();
_videoViewerWF1.Start();
}
As a another solution i finally used Accord.net library to capture rtsp stream.

Websphere MQ - Keeping message context and identity when moving from one queue to another in .NET

I have been tasked with writing a custom application in C#.NET to move messages from one queue to another, while keeping all of the context and identity information the same as the original message.
I have tried to decipher the online docs, and have tried every combination of MQC.MQOO_PASS_ALL_CONTEXT and MQOO_SAVE_ALL_CONTEXT in opening queues, and MQC.MQPMO_PASS_ALL_CONTEXT in put calls, to no avail. I have tried setting the MQPutMessageOptions.ContextReference to both the source and the
destination queues, but I continue to get exceptions, either MQRC_CONTEXT_HANDLE_ERROR or MQRC_OPTIONS_ERROR, and I cannot find enough information in the online docs to determine the problem.
I am using runtime version v2.0.50727, Version 7.5.0.1 of the amqmdnet.dll. If anyone knows the correct open and/or put message option settings I need to use, I would appreciate the leg up. Thanks.
***** SECOND UPDATE *****
Here is a very simple gui program to test the classes, and I get the same results:

The GUI simply prompts for a username and password (which are validated with an LDAP call) and then enables a "test" button which runs the btnTest_Click method. I still get the same exception (MQRC_CONTEXT_HANDLE_ERROR) even thought I have used all the open and get message options specified.

Adding to Morag's answer, here is snippet for moving messages with context. I am also using a SYNC_POINT to ensure the message is removed from source queue after the message is successfully put to the destination queue.
/// <summary>
/// Moves messages from one queue to another with context

public void moveMessagesWithContext()

{
htSource = new Hashtable();
htDestination = new Hashtable();
htSource.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_MANAGED);
htSource.Add(MQC.HOST_NAME_PROPERTY, "localhost");
htSource.Add(MQC.PORT_PROPERTY, 2020);
htSource.Add(MQC.CHANNEL_PROPERTY, "A_QM_SVRCONN");
qmSource = new MQQueueManager("A_QM", htSource);

htDestination.Add(MQC.HOST_NAME_PROPERTY, "localhost");
htDestination.Add(MQC.PORT_PROPERTY, 3030);
htDestination.Add(MQC.CHANNEL_PROPERTY, "B_QM_SVRCONN");
qmDestination = new MQQueueManager("B_QM", htDestination);
qDestination = qmDestination.AccessQueue("Q_DESTINATION", MQC.MQOO_OUTPUT | MQC.MQOO_FAIL_IF_QUIESCING | MQC.MQOO_PASS_ALL_CONTEXT);
MQMessage msgSource = new MQMessage();
MQGetMessageOptions gmo = new MQGetMessageOptions();
gmo.Options |= MQC.MQGMO_SYNCPOINT;
qSource.Get(msgSource,gmo);
if (msgSource != null)
{
MQMessage msgDestination = new MQMessage();
MQPutMessageOptions pmo = new MQPutMessageOptions();
pmo.ContextReference = qSource;
qDestination.Put(msgSource, pmo);
qmSource.Commit();
}
}
catch (MQException mqEx)
{
qmSource.Backout();
Console.WriteLine(mqEx);
}
catch (Exception otherEx)
{
Console.WriteLine(otherEx);

}

The correct options to use to move messages whilst retaining all the context information within them are as follows.
When opening the queue to get messages from, use MQOO_SAVE_ALL_CONTEXT. The context will be saved at get time in the object handle that represents this opened queue.
When opening the queue to put messages to, use MQOO_PASS_ALL_CONTEXT. Then when putting the message, use MQPMO_PASS_ALL_CONTEXT and provide the object handle that contains the context.
Receiving return code MQRC_CONTEXT_HANDLE_ERROR means that you didn't use MQOO_SAVE_ALL_CONTEXT on the first open but then tried to use the object handle on the put. It could also mean that it's just not a correct reference to the first queue. In the MQ API it's an object handle (MQHOBJ) whereas in .Net it's the MQQueue (see MQPutMessageOptions .NET class).
Receiving return code MQRC_OPTIONS_ERROR means that you mixed and matched the options too much.

Update data using n-tier does nothing

I have got 3-tier where carry out my code in business layer I run code for update
public override bool LoadProperties2List(string TypeOfOperation)
{
SortedList Sl = new SortedList();
Sl.Add("#CommandType", TypeOfOperation);
Sl.Add("#UserName",UserName);
Sl.Add("#SecondarySchool",SecondarySchool);
Sl.Add("#University",University);
Sl.Add("#Qualification",Qualification);
Sl.Add("#JobTitle",JobTitle);
Sl.Add("#Company",Company);
Sl.Add("#PhotoUrl", PhotoUrl);
ProcedureName = "MangeUserInfo";
if (db.RunProcedure(ProcedureName, Sl) == 1)
return true;
else
return false;
}
public bool updateUser(string User, string SecondaryS, string Unvi, string Qua, string jobtitle, string company)
{
this.UserName = User;
this.SecondarySchool = SecondaryS;
this.University = Unvi;
this.Qualification = Qua;
this.JobTitle = jobtitle;
this.Company = company;
if (Update())
return true;
else
return false;
}
and in data access layer
public void ConnectDB(CommandType CT,string ProNameSQl)
{
cn = new SqlConnection("Data Source=.;Initial Catalog=Conversation;Integrated Security=True");
cmd = new SqlCommand();
cmd.Connection = cn;
cmd.CommandType = CT;
cmd.CommandText = ProNameSQl;
cn.Open();
}
public int RunProcedure(string ProcedureName, SortedList Paraval)
{
ConnectDB(CommandType.StoredProcedure, ProcedureName);
for (int x = 0; x < Paraval.Count; x++)
{
try
{
cmd.Parameters.AddWithValue(Paraval.GetKey(x).ToString(), Paraval.GetByIndex(x));
}
catch
{
;
}
}
return ExceNoneQuery();
}
and then in another layer I use this method to call procedure process kind and run
public bool Update()
{
return LoadProperties2List("u");
}
at last layer presentation layer
I do that
protected void btnsave_Click(object sender, EventArgs e)
{
//upadate info
bool Result = false;
UsersInfo Upd = new UsersInfo();
try
{
Result = Upd.updateUser(username, TxtSecondarySchool.Text, TxtUniversity.Text, TxtQualification.Text, TxtJobTitle.Text, TxtCompany.Text);
if (Result==true)
lblMessage.Text = "Record Updated Successfully.";
else
lblMessage.Text = "Record couldn't updated";
}
catch (Exception ee)
{
lblMessage.Text = ee.Message.ToString();
} finally
{
Upd = null;
}
}
When I run the code only the result is
lblMessage.Text = "Record couldn't updated";
What is the error which makes it not to work correctly?
I also find something strange that the textboxes doesn't take the new values it pass the same value despite change why? I need help

The error is that the textbox loads in a routine in the Page's Startup event, with the routine placed outside the If IsNotPostback loop. So, the default value just reloads every time the page is refreshed, and thus appears to be 'unchangeable'.

Windows service shuts off after running first record

I have a windows service that is supposed to check for a record, email a report for that record, delete the record and then repeat for the table. It checks for the record, emails a report for the first record then shuts off. Any ideas??
Service code:
namespace ReportSender
{
public partial class EmailReportService : ServiceBase
{
private EmailReportApp _app = new EmailReportApp();
public Timer serviceTimer = new Timer();
public EmailReportService()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
//Set interval (from App Settings) and enable timer
serviceTimer.Elapsed += new ElapsedEventHandler(ServiceTimer_OnElapsed);
//Use Conversion utility to determine next start date/time based on properties, use DateTime.Subtract() to find milliseconds difference between Now and the next start time
//serviceTimer.Interval = Date.AddInterval(Properties.Settings.Default.IntervalType, Properties.Settings.Default.Interval).Subtract(DateTime.Now).TotalMilliseconds;
serviceTimer.Interval = 600000;
serviceTimer.Enabled = true;
}
protected override void OnStop()
{
//Stop and disable timer
serviceTimer.Enabled = false;
}
private void ServiceTimer_OnElapsed(object source, ElapsedEventArgs e)
{
try
{
//Stop the timer to prevent overlapping runs
serviceTimer.Stop();
//Start service
//Run your app.Start() code
_app = new EmailReportApp();
_app.Start();
}
catch (Exception ex)
{
}
finally
{
//Re-start the timer
serviceTimer.Start();
}
}
}
}
Code the service is supposed to execute:

}

The 'ServiceBase' is losing scope once the OnStart method is called. A 'ManualResetEvent' will keep the service open for you.
Use member:
ManualResetEvent stop = new ManualResetEvent(false);
Try this in your main Start():
do
{
try
{
_app = new EmailReportApp();
_app.Start();
}
catch(Exception e)
{
... handle error or log however you want
}
}
while(!stop.WaitOne(0, false))
in Stop(), make sure to do stop.Set()

MsftDiscFormat2Data Event Handler

I have successfully integrated IMAPI2 using Interop.cs into my application. I can burn CD/DVDs without any problem. However, the event handler for MsftDiscFormat2Data update does not work, so I can't get my progress bar moving.
Here is the code I found at codeproject website:

try
{
discFormatData.Write(fileSystem);
e.Result = 0;
}
catch (COMException ex)
{
e.Result = ex.ErrorCode;

e.Result = exception.ErrorCode;
}
finally
{

_burnData.freeSystemBuffer = eventArgs.FreeSystemBuffer;
//

//
backgroundBurnWorker.ReportProgress(0, _burnData);
}
Unfortunately, the update handler gets never called. I looked up everywhere on internet but could not find a solution. I saw some people with same problem but no one was able to answer.
The original code from Eric, http://www.codeproject.com/KB/miscctrl/imapi2.aspx?msg=2695517,
does work for some reason.
Can someone please help me?

I know, it's too late, but I've got the same problem with update callbacks.
Open Project->Properties->Application->Assembly Information and tick "Make Assembly COM-visible".
