Serviio

Hi,

It is possible to only display the appropriate folder/subfolder(s) under each menu on the TV (Sony EX703 in this case). The TV has its own menus for selecting between Photos, Music and Videos once you select the video menu you then select the service i.e. Serviio. So when i am selecting a video to watch Is there a way of just displaying the Video folder or the video sub folders only if "display content only" is selected instead of seeing 3 sub folders of "Audio", "Image" and "Video" and then having to select video, and so on for the Music and Photos Menus on the TV.

Not yet.
Serviio is DLNA compliant. This is a DLNA implementation. But customization were done for Samsung TV. We could open a ticket...

Apparently some other servers can do it. If someone with the TV can figure it out then great

Zip, I believe I know the answer to this one. Windows Media Player when queried adds searchClass elements that tell the viewing device what objects to expect from the container. It looks like this:
<upnp:searchClass includeDerived="0">object.item.videoItem</upnp:searchClass>
What you'll have to do is when the parent container ( 0 ) is queried for Direct children, each folder has to contain 1 or more of those searchClass elements. While I believe you'll only have to use a videoItem, WMP includes container, playlistContainer, genre, movieGenre, movieActor, album and videoAlbum. Music and Photos/Images have similar objects to be used. I can't confirm this because I don't happen to have source code to a DLNA compliant Media Server to modify to test it, but I noticed those differences between Serviio and WMP while attempting to build a Control Point program.

Sounds like a good place to start. Unfortunately my coding skills are not up to scratch and I've never even looked at java. But if i can help in any other way let me know
