updating EPG

[reven]

I'm getting the classic "Object reference not set to an instance of an object." when trying to update the epg.

I original get these two lines back and then the "Object reference not set to an instance of an object."

Code:

Checking for any XMLTV listings Checking for any DVB/ATSC listings

im using the following code to call the update

Code:

static Mutex EpgUpdateMutex = new Mutex(); internal static void UpdateEpg(Action<string> CallBack = null) { Logger.ILog("Update EPG Started"); NShared.EPGManager manager = new NShared.EPGManager(); WebConsoleEpgUpdateCallback wcCallback = new WebConsoleEpgUpdateCallback(CallBack); System.Threading.Tasks.Task.Factory.StartNew(delegate { if (!EpgUpdateMutex.WaitOne(100)) { Logger.ELog("Failed to update EPG, already running."); return; } try { Hubs.NextPvrEventHub.Clients_ShowInfoMessage("EPG Update Started"); manager.UpdateEPG(wcCallback); Hubs.NextPvrEventHub.Clients_ShowInfoMessage("EPG Update Completed"); } catch (Exception ex) { Hubs.NextPvrEventHub.Clients_ShowErrorMessage(ex.Message, "EPG Update Failed"); wcCallback.SetEPGUpdateStatus("ERROR: " + ex.Message); } finally { System.Threading.Thread.Sleep(10000); EpgUpdateMutex.ReleaseMutex(); } }); }

and this is my WebConsoleEpgUpdateCallback class

Code:

class WebConsoleEpgUpdateCallback : NShared.EPGManager.IEPGUpdateCallback { private Action<string> CallBack; public WebConsoleEpgUpdateCallback(Action<string> CallBack = null) { this.CallBack = CallBack; } public bool SetEPGUpdateStatus(string status) { Logger.ILog("Updating EPG Status: " + status); if (CallBack != null) CallBack(status); return true; } }

I believe the object not set is inside the manager.UpdateEPG somewhere, but i get no more information than that. theres nothing mentioned in any of the nextpvr logs.

is this not the correct way to update the EPG? (if its not is there a similar call, or a way I can call it and still get the status of the update as I would like to make this visible to the user, seeing as it can take a while for some setups).

Here's how I do it in the System plugin. These methods are part of a class that implements EPGManager.IEPGUpdateCallback. It's run in its own thread.

Code:

private void EPGRunner() { isUpdatingEPG = true; ClearLabels(); args["@status1"] = "Requesting EPG update event..."; NSystem.statusUpdated = true; Log.Debug("Requesting EPG update"); new EPGManager().UpdateEPG(this); Log.Debug("Exporting recordings"); ExportImport.ExportRecordings(false); Log.Debug("Requesting RELOAD_SETTINGS"); EventBus.GetInstance().Notify("RELOAD_SETTINGS"); isUpdatingEPG = false; } public bool SetEPGUpdateStatus(string status) { // The messages received back from nPVR are either 1 or 2 lines string[] str = status.Split('\n'); args["@status1"] = str[0]; args["@status2"] = str.Length == 2 ? str[1] : ""; NSystem.statusUpdated = true; return true; }

There might be a difference running connecting to the recording server outside of a plugin. I needed a couple of lines I added here

and then you also need the line sub wrote after that.

ok im closer,

Code:

NUtility.PluginRegistry.GetInstance().LoadPlugins(); NShared.RecordingServiceProxy.ForceRemote(); ScheduleHelperFactory.SetScheduleHelper(GetRecordingServiceInstance()); NShared.EPGManager manager = new NShared.EPGManager(); WebConsoleEpgUpdateCallback wcCallback = new WebConsoleEpgUpdateCallback(CallBack);

now doesnt throw the error, i have log messages like this in my npvr.log

Code:

however the update finishes within seconds, and only seems to grab my xmltv listings and doesnt do a scan of my DVB-S listings.
