I am writing my own Control point and I encountered to the following problem: There is no problem to send a single object (mp3, video) to the renderer. To send one artist I need to give the adress of the playlist. The UPNP specification says:
**********************************************************
2.8.9.2. Playlist file generation from container derived object resources
Objects derived from the container class (object.container) may contain objects derived from the item (object.item) or container classes. An example of such a class is the musicAlbum class (object.container.album.musicAlbum). It is desired to allow a control point to set up a rendering session of all the items in the music album. This may be accomplished by having the album object expose a resource property (res), and the URI of the resource generates a playlist file in a format that is understood by the media renderer. The content of the playlist file is a list of all the items in the container.
Note: the order of the items in the playlist file is defined by the generator of the playlist, but should match the order of the items as returned from the Browse() action on that container.
**********************************************************
But I do not see any playlist in the containter with the latest Twonky vision. When I play with the hifidelio: http://www.weitz.de/hifidelio.html
I see correctly for each container also playlist and if I send the container playlist in to the renderer everything works fine. I found out that also Hifidelio is using internally Twonky media server. Where is then the problem? Is there then something extra in Hifidelio to fulfill the UPNP specification, or I am doing something wrong with the Twonky Media installed on my computer?
Tanks for help.
