I have released the UPnP/AV media server as a sample application of mUPnP for C.
The media server is builded as an application of Windows Mobile 5.0. The media server publishes the all photo images in the photo directory, My Pictures, using UPnP/AV protocols, so you can see the all photo images on TV easily using UPnP/AV players such as DLNA media players.
You can use the application as a digital photo frame because the media server shows the photo images by rotation. I installed the application into W-ZERO3 es which has the WiFi card, IMSW-822, so I can see the photo images on TV using VGP-MR100 in my home 🙂
