I get no error message but also hear no sound. I used the chimes.ogg file.

I used minGW64 on windows for the go build. I can start the exe and it connects to my server. If I send the text: chimes.ogg it says: Playing chimes.ogg on the shell window but I can't hear sound. If I move the bot, I hear the text to speach message from the server, so audio ist enabled and working.

Any hints how to debug or what to change?

Hi,

I have begun to rewrite MumbleDJ using your new gumble library (I prefer Go over Lua), and I seem to be having connection issues whenever I try to connect to my server. I have tried both my password-protected Mumble server on an external machine, and an unprotected localhost server and got the same result. Both attempts to connect were executed on an Arch Linux machine.

I followed the start-up guide on your README for gumble, here is my code.

Here's the error message that I get (this one is for localhost, but it is identical to the message I would get for external servers):

panic: x509: certificate is valid for Murmur Autogenerated Certificate v2, not localhost

goroutine 16 [running]:

I have a feeling I may simply be missing something related to certificates, but I didn't really have to mess with those on piepan. Thanks!

(Feature request)

Currently the interval at which audio packets are sent is hardcoded as 10milliseconds. This seems to produce choppy sound for me when using 10ms buffer in mumble. Would it be possible to allow custom audio interval values?

Hi there,

So a recent feature request for MumbleDJ was to make it possible for the bot to automatically reconnect upon server connection closure or kick. I wrote this bit of code, thinking this would do the trick (the panic will not be there in the future, just there for debugging purposes):

func (dj *mumbledj) OnDisconnect(e *gumble.DisconnectEvent) {
    if e.Type == gumble.DisconnectError || e.Type == gumble.DisconnectKicked {
        fmt.Println("Disconnected from server... Will retry connection in 30 second intervals for 15 minutes.")
        reconnectSuccess := false
        for retries := 0; retries <= 30; retries++ {
            fmt.Println("Retrying connection...")
            if err := dj.client.Connect(); err == nil {
                fmt.Println("Successfully reconnected to the server!")
                reconnectSuccess = true
                break
            } else {
                panic(err)
            }
            time.Sleep(30 * time.Second)
        }
        if !reconnectSuccess {
            fmt.Println("Could not reconnect to server. Exiting...")
            dj.keepAlive <- true
            os.Exit(1)
        }
    } else {
        dj.keepAlive <- true
    }
}

However, it doesn't seem to work. Maybe I'm just approaching this wrong? This is what console spits out:

Disconnected from server... Will retry connection in 30 second intervals for 15 minutes.
Retrying connection...
panic: client is already connected

It seems strange to me that the error says that there is already an existing connection when this bit of code is within the OnDisconnect() function triggered by a DisconnectEvent.

Thanks!

Hey there,

I came across a rather strange bug while testing out the Play() function from gumble_ffmpeg. I am using youtube-dl to download the audio from YouTube videos in m4a format at 256k, 44100Hz and the audio playback consistently stops 2 minutes and 44 seconds in.

I have even tested it using different YouTube videos, and it still stops right on 2 minutes 44 seconds. Maybe a memory leak issue or something? The audio playback sounds perfect up until it stops.

Here is the youtube-dl command I am using: youtube-dl --output ~/.mumbledj/songs/<youtube_id_here>.m4a --format m4a <youtube_id_here>

And here are the two songs I used to test it (I picked these at random): https://www.youtube.com/watch?v=5DLTlgzhxFE https://www.youtube.com/watch?v=emGri7i8Y2Y

Thanks!

Hi!

I've come across another issue. Apologies in advance if this is simply another case of me making a mistake. :)

I have been trying to get MumbleDJ to stream audio over Mumble, but I can't seem to get it to work. Here is a step-by-step outline of the steps completed prior to calling Play() on the stream:

1) Audio file is downloaded and stored on disk. I've tested that the audio file is valid by playing it in VLC, the audio works fine.

2) A new source is created via gumbleffmpeg.SourceFile().

3) Audio stream is initialized with gumbleffmpeg.New().

4) Various parameters such as Offset and Volume are set on the newly created stream.

5) Play() is called, and a goroutine is spawned that waits for the audio stream to finish.

To my knowledge this should be the correct procedure for creating and playing an audio stream, but I do not get any audio. opusthreshold is set to 0 in the server's configuration file, so that is not the issue. Another strange thing is that calling State() on the stream after calling the Play() method the state is set to StatePlaying, even though no audio is provided. Also, calling Pause() afterwards correctly sets the state to StatePaused. It seems that the stream is behaving properly besides the fact that no audio is being played.

Any ideas what is going on here? Here are some links to relevant sections of code in case they are of help:

https://github.com/matthieugrieger/mumbledj/blob/refactor/bot/queue.go#L243-L288 https://github.com/matthieugrieger/mumbledj/blob/refactor/bot/queue.go#L324-L331

Let me know if more information should be provided.

Thanks!

I've been using the elapsed time patch here for stopping/resuming audio streams on my server. I needed to change the integer start offset to float to support fractional seconds to avoid small jumps when you resume audio.

I've also got a patch for piepan to use this in the javascript plugin: https://github.com/layeh/piepan/pull/28

Currently my bot will not check if it is permitted to join a channel before joining and therefore crash if it tries to move to a channel it is not permitted to join.

I call perm := event.Sender.Channel.Permission() but I have no idea how to work with the permission object to check for PermissionEnter. I know it's a bitmask but am unsure how to know what bit in the Int to get or really how to get it.

(Sorry if this is a simple question but info on how to do this is hard to come by.)

I'm getting some very strange behavior. When attempting to play a sound, the sound often does not transmit at all when gumble is connected to a remote server, though sometimes it does work. However, if it's connected to a murmur instance running locally (i.e. "localhost") then sounds seem to play just fine. There don't appear to be any errors at all when this happens. Any thing I could be missing? Thanks!

I get the following errors and a crash if I attempt to connect mumble to a server after attaching the gumbleutil.AutoBitrate to the client:

Any particular caveats I should know about regarding setting the AutoBitrate that I may have fallen into here?

client.Attach(gumbleutil.AutoBitrate) is being called before client.Connect()

The crash does not happen if I remove client.Attach(gumbleutil.AutoBitrate)

Thanks!

When I attempt to run go get "github.com/layeh/gumble/opus" I get the following error:

# github.com/layeh/gumble/opus
../../../github.com/layeh/gumble/opus/opus.go:54: e.Encoder.ResetState undefined (type *gopus.Encoder has no field or method ResetState)

I figure I must be doing something wrong but I can't figure out how to resolve it.

I'm developing on Mac OS X 10.11.4 Beta go version go1.5.2 darwin/amd64

Add client config flag to explicitly signal Opus support even when the Opus audio codec is not loaded.

This is useful if a client based on gumble doesn't actually process audio at all. By signalling Opus support anyway, this doesn't force everyone back to CELT if a gumble client is the only client not claiming Opus support. We can't be sure that the server admin has actually set opusthreshold = 0, so this is a pure-client way to prevent a CELT fallback.

Hello! Forgive me if this question is very simple to answer, since I am very new to go lang, but I can't seem to find how to get the stream's duration. I can easily obtain how much time has passed with Elapsed(), but I can't seem to find a method for how long the stream is (in time).

When I run mumble-audio-player, I can connect the mumble-server, but it shows gumble user, named "gumble-client" by me cannot transmit or receive any audio, but I have changed the config "opusthreshold=0" in murmur.ini.

Also, when I run mumble-audio-player, it shows that "audio player loaded! (0 files)", and no sound played. Is it normal? I think it should find chimes.ogg in path "../go/src/layeh.com/gumble/_examples/mumble-audio-player", but it not. Is it an error, or chimes.ogg on an incorrect path?

More information or hints about how to debugging gumble for audio is needed.

Hello, golang newbie here. I tried a lot of things to use this interface without changing the lib code but couldn't find a way to implement it.

This change allows me to implement the interface and provide my own functions to use it. Is this a good idea?

Since https://github.com/mumble-voip/mumble/pull/4209 has been merged (and will most likely be included in the Mumble 1.4.0 release) it would be nice to have the ability to transmit stereo audio implemented into gumble.

Presumably, at a quick uninformed glance, all that would need to change would be setting AudioChannels to 2 although it might be more complicated than that. https://github.com/layeh/gumble/blob/1ea1159c495624266a4adea43580748fd0fc9c57/gumble/audio.go#L30

Supposedly the "opus decoder can also automatically convert a stereo stream into a mono stream, so even if we transmit a stereo stream to an older version of mumble, it would still work." according to the author of the PR.

Regardless, it is probably sensible to default to mono still (since 1.4.0 hasn't released yet) with a configurable option to transmit in stereo.
