I got a Samsung Frame TV model 2021 (User-Agent:
DLNADOC/1.50 SEC_HHP_Samsung The Frame 50/1.0 UPnP/1.0
).When browsing to any DMS based DLNA server, it displays an empty content directory.
I went through the painful debugging process and started comparing every piece of the protocol with MiniDLNA responses (that is working smoothly), mismatching case sensitivity in header names, removing non-standard looking fields from the XML responses, forcing the SPCD descriptor to be the same, etc.
The resolution of this issue was to patch the entity encoding of the DIDL-Lite envelope.
