UPnP / DLNA Media Server for MediaPortal 2 (1 Viewer)

[morpheus_xx]

Also server plugin can provide own language files, i.e. to provide localized messages via UPnP.

There is a simple example: https://github.com/MediaPortal/Medi...l/Source/Backend/BackendComponents/ServerBase

Important part is to register the language folders in plugin.xml: https://github.com/MediaPortal/Medi...ckendComponents/ServerBase/plugin.xml#L22-L24

Sorry to bother you:
I read this:

/// <summary>
/// Returns a resource locator instance for this item.
/// </summary>
/// <returns>Resource locator instance or <c>null</c>, if this item doesn't contain a <see cref="ProviderResourceAspect"/>.</returns>
public IResourceLocator GetResourceLocator()

And this code:

var mediaIteamLocator = item.GetResourceLocator();

returns 'null'

What are the reasons that the ProviderResourceAspect is unavailable?
If I take a look into the DB I have 77 entries for in the MediaItem Aspect and 77 entries in Resourceprovidersource table.
But I get for every MediaItem 'null' while trying the Resourcelocator...

Part of the whole function:

public static MetadataContainer ParseMediaItem(MediaItem item)
    {
      MetadataContainer info = new MetadataContainer();
      var mediaIteamLocator = item.GetResourceLocator();
      try
      {
        var mediaItemPath = mediaIteamLocator.NativeResourcePath;
        var mediaItemDirectoryPath = ResourcePathHelper.Combine(mediaItemPath, "../");
        using (var mediaItemAccessor = new ResourceLocator(mediaIteamLocator.NativeSystemId, mediaItemDirectoryPath).CreateAccessor())
        {
          //IResourceAccessor mediaItemAccessor = item.GetResourceLocator().CreateAccessor();
          if (mediaItemAccessor is IFileSystemResourceAccessor)
          {
            using (var fsra = (IFileSystemResourceAccessor)mediaItemAccessor.Clone())
            {
              if (!fsra.IsFile)
                return null;
              using (var lfsra = StreamedResourceToLocalFsAccessBridge.GetLocalFsResourceAccessor(fsra))
              {
                info.Metadata.Source = lfsra.LocalFileSystemPath;
              }
            }
            info.Metadata.Size = new FileInfo(info.Metadata.Source).Length;
          }
          else if (mediaItemAccessor is INetworkResourceAccessor)
          {
            using (var nra = (INetworkResourceAccessor)mediaItemAccessor.Clone())
            {
              info.Metadata.Source = nra.URL;
            }
            info.Metadata.Size = 0;
          }
        }
      }
      catch (Exception ex)
      {
//#if DEBUG
        var name = item.Aspects[MediaAspect.ASPECT_ID].GetAttributeValue(MediaAspect.ATTR_TITLE);
        Logger.Warn("DlnaMediaServer: Error while accessing Mediaitem '{0}' in ParseMediaItem()", ex, name);
//#endif
        info.Metadata.Size = 0;
      }

Log:

[2015-09-10 09:52:15,509] [31125 ] [39 ] [WARN ] - DlnaMediaServer: Error while accessing Mediaitem 'Covert Affairs S04E13 - No. 13 Baby' in ParseMediaItem()
System.NullReferenceException: Object reference not set to an instance of an object.
at MediaPortal.Extensions.MediaServer.MetadataExtractors.DlnaVideoMetadataExtractor.ParseMediaItem(MediaItem item) in m:\Programmieren\C#\MediaPortal 2\MediaPortal\Incubator\MediaServer\MetadataExtractors\DlnaVideoMetadataExtractor.cs:line 235

Edit:
The exception is caused because 'mediaIteamLocator ' is null

How did you load the MediaItems? Usually you need to pass the AspectIds you want to include, did you miss the ProviderResourceAspect?

 

[henso]

GUI strings? Which GUI strings? The Media Server doesn't even have a gui

I just get a lot of exceptions in a function called TryToTranslate or something similar. So I assumed I was missing some translations. I think it was for the FriendlyName, Manufacturer etc. for the UPnP device.

First of all thank you for your answer! I don't know what we would do without you
I've added this to the search query:

      necessaryMIATypes.Add(ProviderResourceAspect.ASPECT_ID);

ISet<Guid> necessaryMIATypes = new HashSet<Guid>();
necessaryMIATypes.Add(MediaAspect.ASPECT_ID);
necessaryMIATypes.Add(ProviderResourceAspect.ASPECT_ID);
IFilter searchFilter = SearchParser.Convert(exp, necessaryMIATypes);
MediaItemQuery searchQuery = new MediaItemQuery(necessaryMIATypes, null, searchFilter);

[...]

IList<MediaItem> items = ServiceRegistration.Get<IMediaLibrary>().Search(searchQuery, true);

var msgBuilder = new GenericDidlMessageBuilder();
var o = deviceClient.RootContainer.FindObject(containerId);
if (o == null)
{
// We failed to find the container requested
// throw error!
throw new ArgumentException("ObjectID not found");
}
IEnumerable<IDirectoryObject> objects = items.Select(item => MediaLibraryHelper.InstansiateMediaLibraryObject(item, MediaLibraryHelper.GetBaseKey(containerId), (BasicContainer)o));
msgBuilder.BuildAll(filter, objects);

on GitHub:
https://github.com/MediaPortal/Medi...erver/UPnPContentDirectoryServiceImpl.cs#L473

Now it looks like it is working

@Lehmden
Could you try the import again please? I changed the call to ffmpeg.exe and now I hope it should work (I copied it from the Thumbnail generator^^)

You also need the patched HttpServer and UPNP.dll from here:
https://forum.team-mediaportal.com/...for-mediaportal-2.104128/page-27#post-1151412

Again it is recommended to make a backup of the DB

@breese
this version should also fix your exception

I can't confirm that. Do you have a stack trace?

 

[Lehmden]

Hi.

Could you try the import again please?

Later today... Now I'm not at home...

 

[breese]

Does this require the httpserver and upnp dll's?

Yes
