upmpdcli

[jymyj]

Dear developper,

I have just installed nextcp2 and it detects all AV UPnP servers and renderers connected to my local network, but the upmpdcli renderer, although it is detected by my other CPs (e.g. upplay).

upmpdcli and nextcp run on the same machine. A detailed log is attached that shows an error related to upmpdcli detection (line 4164).

Could you please also provide the nextcp2 server logs. I think upplay and upmpdcli are from the same developer, therefore they work good together ...

Did you build the software from source, or downloaded a release?

[jymyj]

I downloaded the java archive.
A brand new log is attached.
The name of the upmpdcli is "MusicMaid - Playback"

From the logs I cannot see anything. It looks like all services are registered just fine. Maybe a TRACE log level could help more.

I've also added 2 new releases. Please try 2.6.1 which uses the latest jupnp driver library.

[jymyj]

I just installed and run the last version in TRACE logging mode. The situation did not improve. The log is attached.

Dou you have another control point in use, that show's upmpdcli as a media renderer, like BubbleUPnP or LINN ?

[jymyj]

Yes, three of them. They all show upmpdcli as a renderer. NextCP is the only one not to show it.

Sorry to jump in, I have a similar problem with nextcp2.
It detects a MinimServer running in my local network but not MediaPlayer on the same network (MediaPlayer isn't shown in "Media Renderer").

NextCP runs in docker container on my QNAP NAS and the MinimServer runs on the same device. The NextCP container is pingable to every host on the network where the MediaPlayer (raspberry pi) works.
FYI, BubbleUPnP controller app can find it.

The log is attached below. Could you help me inspect the problem?

Hi padacha. If nextcp2 is started within a docker container, please add --net=host to the docker run ... command like

docker run --net=host [your start parameter]
MediaPlayer will show up.

Maybe it's worth using UMS media server as a music backend, because some functionality (i.e. playlist support : editing / sidebar display or global search) may not be supported in MinimServer UPnP stack (yet).

[sf666]

You could also try version 3.0 I've just released. It has an updated UPnP stack and some other improvements ...

[padacha]

Thank you for your advice and new release.
As you said, the MediaPlayer has shown up by adding --net=host to docker run ... !
In turn, however, my nextcp2 shows MinimServer as "OFFLINE" although it works (I guess it is due to the docker network but don't have any further idea...).

Just for your information, the docker command is below and Dockerfile is attatched.
docker run --net=host --restart=always -d --name nextcp2_dev nextcp2:latest
Dockerfile.txt

I began to think about using UMS media server instead or MinimServer on a docker container.
I would like to add to this comment if any solution found.

[sf666]

@padacha All UPnP member devices must be on the same network to see each other. Do you also start MinimServer in a docker container? If so, please also add --net=host to the docker run command.

I think, there is also a docker container for UMS you can try out ...

[jymyj]

I have tried the new version but my mpd instance is still not identified by NectCP (through upmpdcli). A log is attached.

[sf666]

@jymyj Yeah, I see only the Upmpdcli media server is found ... I believe I need to install a copy of umpmdcli client to test this. I have not a running version yet on my system ...

[sf666]

@jymyj , @padacha I have installed a MPD/upmpdcli in an docker environment from here :
https://hub.docker.com/r/giof71/mpd-alsa and https://github.com/GioF71/upmpdcli-docker?tab=readme-ov-file.

For showing up in other control points it seems like you have to enable UPnP AVTransport Services. With the docker image add -e UPNPAV=1 to the docker run command.

By default in upmpdcli AVTransport services are not enabled.

[jymyj]

Indeed, this small change in the upmpdcli config makes things appear in the NextCP interface. Thanks!
