TV4Home - WCF Webservice for MediaPortal TV Server (3 Viewers)

Ooops that's my fault i will correct it!

please add a method to only retrieve a base channel (id, name, groups, ...).

You mean without the next and current program object? That will be implemented soon

//edit fixed

 

[Mike Lowrey]

I've released a new version of the Core Service.

New things are better methods for mobile clients:
Basic channel lists
channel lists by Range

and some other issues

The implementation of multiple streams per client will need a bit more time.

I get the following error when trying to start a timeshifting from C#.NET:

[FaultException`1: No connection could be made because the target machine actively refused it 10.1.1.21:31456]
   System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) +10257978
   System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) +539
   MPWebStream.TVEInteraction.ITVEInteraction.SwitchTVServerToChannelAndGetTimeshiftFilename(Int32 channelId) +0

   System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +586
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +177

Basically, my code is this:

            // connect to TV4Home service
            // FIXME: make configurable
            EndpointAddress address = new EndpointAddress(String.Format("http://{0}:4321/TV4Home.Server.CoreService/TVEInteractionService", "mediastreamer.lan"));
            TVEInteractionClient tvWebClient = new TVEInteractionClient("BasicHttpBinding_ITVEInteraction", address);
            WebChannel ch = tvWebClient.GetChannelById(301);

// more things not so relevant

                sourceFilename = tvWebClient.SwitchTVServerToChannelAndGetTimeshiftFilename(ch.IdChannel);

Am I doing something wrong or did I just hit a bug? Weird thing is that the GetChannelById() call works, but the next one fails.

(full sourcecode is available here, mainly MPWebStream/Streamer.cs is interesting).

The implementation of multiple streams per client will need a bit more time.

Maybe you could implement a method or an additional parameter to set the User name. This way the caller could pass a new name for each request and all the handling is done in TvServer like before.

AW: TV4Home - WCF Webservice for MediaPortal TV Server

Oxan try this one
it works here in the mce client
Private Fields:
private ITVEInteraction serviceinterface;

Constructor:
serviceinterface = ChannelFactory<ITVEInteraction>.CreateChannel(new NetNamedPipeBinding() { MaxReceivedMessageSize = 10000000 }, new EndpointAddress("net.pipe://localhost/TV4Home.Server.CoreService/TVEInteractionService/"));


Public Method
public void StartTimeShift(Int32 channelid)
{
string rtspUrl = "";

try
{
rtspUrl = serviceinterface.SwitchTVServerToChannelAndGetStreamingUrl(channelid);
}
catch (CommunicationException ex)
{
Logger.Log(ex.ToString());
rtspUrl = serviceinterface.SwitchTVServerToChannelAndGetStreamingUrl(channelid);

}
if (rtspUrl != "")
{
rtspUrl = rtspUrl.Replace(":554", "");
Play(rtspUrl);
}
}

KayDiefenthal: thanks, that works!

mike: could you implement the option to set more advanced options when creating a schedule, such as preRecordInterval, postRecordInterval, keepMethod, keepDate, directory & priority?

 

[Mike Lowrey]

Hi, yes that's possible, i will have a look on it.

Any other missing feature?

 

[Oxan]

Thanks!

Just some other random things:
- It can be nice to link the output of GetCards and GetActiveCards (return VirtualCard.Id in the GetActiveCards output)
- and maybe also in GetActiveUsers?
- Add the type of a card to thte GetCards output?

 

[Mike Lowrey]

Hi, sorry for answering so late.

I will have a look on your suggestions - the other one mentioned request is done & committed

 

[Oxan]

I see, thanks! However, the Directory property is relative to the recordingFolder setting and is automatically created, so the check for existence is wrong here.

For the other suggestions I've prepared a patch:
* It adds a DeleteSchedule(scheduleId) method
* It adds a UserName and IdCard property to the WebActiveCard class and a IdCard property to the WebActiveUser class
* It changes the WebActiveCard.Channel and WebActiveUser.Channel properties to int IdChannel properties to save bandwidth and to be consistent with the rest of the API. This may be problematic with the rest of your app and other users, so you may leave this part out.

Thanks for your work!
