Mumble: Shortcut to listen to a channel

[absfilho2]

I believe that this implementation can be used for broadcast communication and also for games that want to hear a channel that is rolling a song for example.

Could you put a shortcut so you can start and end listening to a certain channel?
If you can have the implementation of a shortcut also to adjust the level of the channel. It will be perfect.

Hi. I'm new and looking to help out on this project! Is this an issue that I'd be able to pick up and work on?

[Krzmbrzl]

@timjwkim great to hear that! :)

Yes this should be fairly easy to implement. To see how shortcuts can be added to Mumble, have a look at this recent PR: https://github.com/mumble-voip/mumble/pull/4562
You need a bit more but if you poke around in the respective code parts you should find all you need.

And furthermore you'll need to know how to add a new listener. For that, have a look at
https://github.com/mumble-voip/mumble/blob/13098748a9badf85f1faac65574570c3e9be3478/src/mumble/MainWindow.cpp#L2247
(in order to use this function, you'll have to have included Global.h in the source file you're editing - which usually is the case already anyways).

If you have further questions and/or need help, let me know :)

I forked a clone of the current Mumble repository. After running through the steps located in the build instructions for MacOS, I run into this compilation error. Is there something I am missing?

[Krzmbrzl]

I assume you are following the build instructions located in this repo, right?

In case you are following the instructions on the wiki: They don't apply for the master branch anymore

[timjwkim]

Yes, I am following the build instruction located in that repo.
I decided to re-clone and re-build. One thing I ran into is:

which I resolved by the submodule git submodule update --init --recursive and re-running cmake.

I continue to run into the issue mentioned above which happens when "Linking CXX executable ../../Mumble.app/Contents/MacOS/Mumble"

[Krzmbrzl]

Okay that's interesting. From the error mwssage I assume that for some reason you habe installed a 32bit version of OpenSSL but are building a 64bit version of Mumble.

Could you verify that the OpenSSL version installed via homebrew is 64bit and that you are actually linking against this spwcific OpenSSL version and not any other onw thst might be installed on your system?

@TerryGeng do you have an idea what might be the problem. As you know my MacOS knowledge is very limited ^^

[timjwkim]

It seems like I am using the 64bit version of OpenSSL. The only issue I can think of is that I am somehow linking another version of OpenSSL. Is there a way I can confirm that I am using the 64bit version of OpenSSL when building and compiling?

[davidebeatrici]

It's possible that it's linking to Apple's SSL library.

I would try to pass -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl to CMake.

[timjwkim]

That did the trick! Thank you so much!

[davidebeatrici]

No problem!

We should probably add a note to https://github.com/mumble-voip/mumble/blob/master/docs/dev/build-instructions/build_macos.md.

Hi! Quick question: is there a public server accessible in Mumble in which I could use to test the changes that I make in my mumble build? Or do I need to setup my own Murmur server?

[davidebeatrici]

Hi! I generally start a local server to test changes, so that I can easily test server-side ones as well.

[timjwkim]

What is the general method of listening into channels? When I right-click on a specific channel it does not come up in the dropdown menu.

[kripton]

Which version of server and client are you using? Listening to channels is a feature that has not made it into any release

[Krzmbrzl]

As kripton said. As this is a feature that requires server-side support, it will only be shown in the context menu if the server's version is 1.4.0 or higher. Thus you'll probably have to use a locally hosted server that is running the current state of the master branch

[timjwkim]

I have been using the current state of the master branch (version "1.4.0"), but I have only been using the latest available server on the mumble site -- so that was my mistake. After switching to the server build available on the current state of the master branch, I got an error saying that I failed to set TOS for the UDP and TCP Sockets:

EDIT: retried and it just worked, but not sure why

[Krzmbrzl]

I have never seen this error before. Maybe this is some security feature of macOS with regards to TCP sockets? :thinking:
