Announce: SMD, let's discover the music

[vagskal]

The warning messages in the previous post finally went away and the scan continued. But now the scan has stopped again with this error meddage.

Did you see anything in the server.log in SBS at the same time ?
Or did SBS restart or something similar when you got this ?

Hmm the extra scans SMD performs after adding some new albums definitely breaks music playback for at least >30 minutes, while it hogs the whole cpu

It's going to improve because currently we haven't implemented any incremental scanning, it basically scans the whole library if you only add one album.

If it still breaks music playback it should be pretty easy to slow it down a bit so the music gets higher priority.

No, no restart or SBS scan at the time.

I think I have found the right section of my now _huge_ server.log:

Abort scan does not abort SMD scan....

[vrobin]

Don't urn:upnp-org:serviceId:AVTransport and urn:upnp-org:serviceId:RenderingControl provide all the functionality that is needed?

Not really, AVTransport exposes (extract from WMP):
SetAVTransportURI
GetMediaInfo
GetTransportInfo
GetPositionInfo
GetDeviceCapabilities
GetTransportSettings
Stop
Play
Pause
Seek
Next
Previous
GetCurrentTransportActions

And rendering exposes:
ListPresets
SelectPreset
GetMute
SetMute
GetVolume
SetVolume


But there's no playlist management, if you "play" a playlist file or if a disc or dvd is playing, next and previous can change tracks, but you can't access the playlist, change it, etc.
If we continue this way, the only solution would be to generate m3u files "on the fly". I kinda dislike it. I know there are some proprietary services (for linn devices, for media centers) to deal with these questions, but that's far from a perfect solution.

Looks interesting. Will this eventually work with Rhapsody (and other services?) so I can have a combined library with both my local music and my Rhapsody library in one menu? Will it provide a rating system for non-local tracks?

Yes, that's one thing that's in the plan, I can't say for sure exactly which services we will support at the moment.

We actually support an extremely preliminary integration of Spotify tracks already now where you can add Spotify music to your library. You do this, by open the context menu (More button (Radio/Touch/Controller) or hold+play (Classic/Boom/Transporter) and select "On Spotify" and then browse to the related Spotify album, track you like to import and open the context menu from that and select "Import from Spotify". This is just a very preliminary implementation to show the concept, it will got a lot better before we are finished.

The plan is to support this kind of integration of third party services through a plugin system, where it's also possible for other third party developers to add support for their favorite streaming service.

For playback of these streams we rely on standard Squeezebox Server, so when you select to play a Spotify track through the SMD menu it will be played back through Logitech's standard Spotify plugin or Triode's third party Spotify plugin.

Will it provide a rating system for non-local tracks?

Rating support is definitely on the agenda, both for local and online tracks like Spotify/Rhapsody and other services supporting playback of individual tracks.

The main reason for supporting ratings is to support a user friendly smart playlist functionality which is also something we would like to support eventually.

However, it should also be said that we really need more core contributors in the project who can contribute as developers if we like to speed this up, because currently the progress is limited by the amount of spare time the current core contributors have. With the current progress it's going to take a while before we support all of the above mentioned functionality.

I have added the repository of SMD on the plugin page, then I have selected the plugin in the list and restarted hen asked, then ... gone. I don't see the plugin on the plugin page and SBS keeps asking to restarts.

I already had the same with playlist manager a few weeks ago. I selected it in the list, restarted and then ... gone.

Now, I'm sure there is a problem with the plugin installation. How can I resolv that ?

Thanks,
