We get a lot of reports of UPnP AV clients not working properly with Rygel. It either isn’t seen by the client at all or does not show any content.
The reason is usually the same. People are not following the specs. Rygel seems to be one of the few UPnP-AV/DLNA server out there that implements a higher version of the UPnP-AV specification than :1. A lot of clients are explicitly testing for this version, ignoring higher versions although the UPnP standard states that higher version services need to be backward-compatible. (cf. UDA 1.1, section 1.2.2, last paragraph on page 10). Of course we can work around that – and we do, but the list of exceptions is getting longer and longer and to be honest I’m starting to get really annoyed of those fixes.
I expect that there will be more and more devices with higher versions now that DLNA has added features that require higher versions of the specification than :1. So pretty please get your clients fixed. And if you don’t want to, then don’t make it extra complicated to work around your bug. But really, fix it.
And please have a working support email address so I can complain directly. About every client author I tried to contact has bounced – and the rest ignored me.
