Mopidy only plays one song when using snapcast

[vdbee]

To configure Mopidy (on a RPI2) such that it can make use of snapcast it has to output to a FIFO buffer. This works fine except for the fact that Mopidy now only plays a single song while its que is filled.

Might be relevant: this RPI2 has both the snapclient and snapserver running.

I pasted the complete Mopidy log below, but some lines are particular for the situation:
When I hit play Mopidy adds this to the log:
WARNING [3705:MainThread] mopidy.audio.gst: Element doesn't implement handling of this stream. Please file a bug.
When the song ends or the second song starts (I don't know) Mopidy adds this to the log:
ERROR [3705:MainThread] mopidy.audio.gst: Could not perform seek on resource.

I configured my sound as follows:
[audio]
mixer = software
mixer_volume = 100
output = audioresample ! audioconvert ! wavenc ! filesink location=/tmp/snapfifo

output = alsasink

Any idea how to improve my configuration?

I have no idea what snapcast is, but my guess is that you are having problems because we close, and then reopen the outputs between tracks. Go ahead and give develop a go as we recently landed most of the gapless fixes which are meant to resolve this exact issue.

[vdbee]

Thaks for your quick response. Getting develop up and running, using mopidy documentation, is beyond my skills for now.. Any idea when the new version will arrive?

[adamcik]

Probably this year, but essentially when it's ready :-)

Oh, and as this is a FIFO endpoint, it might not be that simple :( I've previously looked into FIFOs for #775 and gapless might help, but I won't guarantee that it alone is really enough.

[vdbee]

.. Tried a bit harder... Yes, the develop version solves my issue. Thanks!
