Automatically re-configure snapcast groups based on playing streams

When clients are in an Idle group and one client's preferred stream starts, both clients play it

markferry opened this issue · comments

os: Arch linux
snapclient: 0.25.0
snapserver: 0.25.0

First off, I realise this is a side-effect of how Snapcast works when removing clients from groups ;)

In this scenario:

  • there are two clients c1 and c2
  • each client has its own preferred stream (s1, s2)
  • a "party" stream s0 is lower priority and plays to both s1 and s2

To repro:

  • Play s0 such that c1 and c2 form a playing group g0.
  • Pause s0 -> c1 and c2 remain in g0 which is Idle
  • Play s1 -> the group splits

Result:

  • c1 is in group g1 playing s1
  • c2 is in group g2 playing s1 <-- DOH!

Expected:

  • c2 remains in group g0 which is Idle

Config:

---
server: tcp://localhost:1705
streams:
  Canard:
    clients:
      - canard
  Kitchen:
    clients:
      - kitchen
  Party 1:
    clients:
      - canard
      - kitchen

The result is the same even with more clients in g0. All clients end up in individual groups playing s1.

I wonder, would it be possible to catch unnamed groups that have only one client and update its stream based on config? (and name it at the same time...)

Hi @markferry - glad to see someone else finds this tool useful!

I hadn't noticed your issue yet, but I actually saw this behavior myself the other day. I added some behavior that actually just muted groups like this, to work around it - see this commit range: 5a424a7...main

I wonder if that solves the problem well enough for you? If not, I can look into trying to handle it more robustly.

Thanks Andrew, just back at this now.

The commits on main seem less reliable than before.

I'll dig deeper tomorrow, but in the meantime I've noticed:

  • fails to group streams when it should
  • flickery muting/unmuting of one group/stream/client

Here, for example is the flickering of the party1 group:

@markferry I'm surprised, honestly - this fixed the similar problems I was seeing at my house. But, clearly, it's not the right answer. I'll dig into this a little bit tonight and see if I can't figure something out. I wrote this whole thing on some fancy new ruby async libraries and didn't write tests or anything, so there's probably horrible bugs to work out. I appreciate the report, and the patience!

(Of course, if you think you know how to fix it already, PRs are always welcome - but otherwise I'll work on this a bit tonight. 😄 )
