This is a good solution for what you need. You could either run two Docker instances or run a regular MinimServer instance and a single Docker instance. With either of these approaches, only one license activation from your limit of 3 device activations will be used.

I did mention the Docker requirement as it can be a sticking point, but I don't understand "slow transferring data". Are you saying that the Docker build itself was slow? Given that both BubbleUPnP Server and MinimServer have similar dependencies (Java) I'd assume the build size and duration would be very similar.

I've been using BubbleUPnP Server for years and I've never had, or heard of it crashing MinimServer. If you have any logs or crash dumps I think bubbleguuum and simoncn would be very interested.

BubbleUPnP Server deosn't allow you to create a DLNA proxy of a DLNA renderer so an OpenHome control point is required, which usually isn't a problem given the lack of decent options on iOS and the benefits of removing the queue from the phone.
I've heard of JPLAY but what's the Auralic app called?

I'm not going to argue with you there; it's worth every penny and then some.

I was trying to not be verbose, but since you asked...
I'm not clear on all the symptoms, I kept trying different permutations rather than troubleshooting through logs etc. I already had Minimserver running on Synology. BubbleUPnP Server running in the Docker container didn't play nicely with Minim running natively. Library transfer was painfully slow.

So then I uninstalled Minim and installed it in Docker.

I should preface by saying that my preferable control point is Jplay but it is not OpenHome. My second is Auralic's Lighting DS app. Auralic calls the connection to their streamer a "Lightning Connection" with UPnP a switchable option. With a bit more reading I learned that Lightning is their name for OpenHome and they say it is completely compatible.

So, with Minim in Docker my control points could see the Bubble proxy library, but when selected, they would not download the library data. Strangely, the Linn and Lumin apps did work, although they were slow and clunky. Unfortunately I find them woefully inferior and I'm not ready to go to apps that feel a decade old. Could be a routing problem, but other control points working points another direction and I may not have the bandwidth to sort that.

Bubble is a simpler solution although fewer transcoding options. I never was able to test if it would do what I want which is:
1. Have one end point that will transcode 2xDSD to 1x DSD, preferably with the Jplay control point, and leave all else untouched
2. Have a second end point that will transcode anything DSD to 24/192 and leave everything else untouched preferably with the Auralic Lightning DS end point

Lastly I tried just running two instances of Minim but now I can't get transcoding to work with Minim in a Docker container. I suppose that is another question for Simon.

Have you installed FFmpeg in the Docker container?

What exactly does "can't get transcoding to work" mean? For example, is there an error message?

There is nothing AFAIK that can transcode 2x DSD to 1x DSD in real time. You will need to use an offline converter for this.

It sounds like you were proxying MinimServer (Media Servers > Create a proxy Media Server on this LAN) which you don't need to do. Given both JPLAY and Lumin copy the entire library to the phone (which is not how normal UPnP control points work) this could have slowed things down.

To enable transcoding you just need to proxy (Media Renderers > Create an OpenHome renderer) the renderers and apply the config, then play to them in your control point from the normal MinimServer library.

Anyway, JPLAY isn't OpenHome so I'll leave you to it.

Wow, thanks for the quick reply. I believe my problem is that I don't know how to get FFmpeg installed in Minim in the Docker container. I followed the instructions, installed v6 in Synology but stream.converter refuses the addresses in the guide. I also put the binary in the /bin folder, but Minim in Docker doesn't see these. Maybe I used the wrong binary?

I also tried installing an FFmpeg Docker container but that wasn't recognized and again, not sure I got the right container.

I don't see instruction on the "Running MinimServer 2 in a Docker container on a Synology NAS" page, or any of the Docker instructions. Unfortunately I'm needing a bit more guidance. Sorry.

Thanks for clarification on inability to go 2x to 1x DSD, that is a limitation that I can live with.

You need to copy the ffmpeg static binary executable to the correct location inside the container. See this thread for details of this location. The container doesn't have access to the ffmpeg executable in the main Synology filesystem. After doing this, stop and restart the container.
