opusthreshold set to 0 still fallbacks to CELT about mumble

Adding a bit more info:
Server running linux static build 1.2.4.

Actual server running: ubrukelig.net (default port), also found under Norway and Ubrukelig.Net in server list.

From IRC:

19:59 @mkrautz https://sourceforge.net/p/mumble/bugs/992/ <- hmm, 'interesting'...

20:13 @pcgod mkrautz: I can't see how that's possible... but opusthreshold won't disable CELT and if there are clients without opus support they're still able to use CELT

Maybe that is what you're seeing?

I was pretty sure this should deny all others than Opus users? Even if they could connect. But so far they just connect, the entire server is falling back.

Random debug tip:
Tell us what the "CELT codec switch" line in the log says, when someone without Opus connects.

Will do when server is empty, must wait for now.

From the logs:

2013-06-03 16:42:26.627 1 => CELT codec switch ffffffff8000000b ffffffff80000010 (prefer ffffffff8000000b) (Opus 1)

Connected here with 1.2.3 linux client.

What does this say:

CELT codec switch ffffffff80000010 0 (prefer ffffffff80000010) (Opus 1)

I don´t understand it, but i get that when choosing Opus 0.

Does mine work, or does it change to Celt?

It changes to Celt, cannot force Opus to be run atm.

[pcgod]

Acutally "Opus 1" means that it's in Opus mode and there is a check to drop all voice packets which aren't Opus when Opus is enabled... so I can't see why this shouldn't work.

@davidebeatrici do you know, if this has been changed/fixed?

[davidebeatrici]

Unfortunately not, we should check whether it can be reproduced in 1.3.

I checked with Mumla and the "Disable Opus Codec" checked. With "opusthreshold=0" in murmur.ini it crashes immediately after connecting to the server. With "opusthreshold=100" it works fine and CELT is used.

I'm not sure if this is the best test, but it seems like it is working as intended (besides the bug in Mumla).

@streaps thanks for testing. Let's assume the best and close this issue for now :)
