Roku Ultra (4400X) Renderer file

Anyone have a Roku Ultra (User-Agent: Roku/4400X) render file?

I can get UMS to recognize the Roku Ultra and I can get MP3 audio files to play. However, any video I try to play just hangs while "retrieving" (that's what is says on the Roku) and never starts playing.

These are the last (I think) relevant lines in the log:

Any ideas? I don't know much about this stuff...

Did you ever get this to work? Would really like to be able to use a Roku with UMS

I'm thinking of purchasing a Roku Ultra but from posts on this forum it seems that it doesn't work well with UMS.

There is a GitHub issue open on this ... ssues/1752 but I'm not clear on the status.

For some detailed information on this problem, see my post of 4/8/2018, at: ... =30#p36108

Basically, I noted, as have other posters, that UMS apparently does not work for native (i.e., untranscoded) video support for Roku Ultra, Premier, etc., using the Roku Media Player. Serviio, however, does support native video well on Roku devices.

AFAIK, that is still the current status. I.e., I have seen no indication from UMS developers or any UMS users that anything has changed. For all I know, the problem with the Roku Media Player getting stuck at "retrieving..." on videos from UMS may even be a minor problem in the interface between UMS and the Roku Media Player, one that UMS could circumvent with a small amount of code once it is identified.

The last comment I have seen from UMS development on the matter was in April, 2018, at: ... ku-support
At that time, SubJunk commented that they had "fixed" Roku support by making UMS transcode everything. Of course, this was "a pretty bad fix," as SubJunk frankly noted.

UMS is a wonderful server, having numerous excellent capabilities that are superior to those of Serviio. Considering this, and considering the enormous market share that Roku has, it would certainly be welcome to have UMS support for the native video capabilities of the Roku devices.

In the meantime, I use UMS to serve all my devices except Roku devices, but necessarily use Serviio to serve my Roku devices.

If anyone has any information to the contrary, please so post.

Well I did order the Roku and I'm happy with it, but not because it works well with UMS or Serviio. It's because I discovered that the combination of Roku and Plex (specifically, the Plex app on the Roku and the Plex server on a PC) solves all the problems I was having with DLNA. Having used DLNA for years I just assumed that it was the best way to stream content from a PC, but Plex has taught me otherwise. Since Plex is basically free (there is a paid version but most of the features anyone needs are in the free version), I don't see much demand for any DLNA-based product to go out of it's way to support the Roku or any STB for which the Plex app is available.
