No sound output NDI- Receiver

[bitSpaz]

Hi @roymacdonald,

I'm trying to use the ofxSoundobjects-NDI addon on a couple projects I'm working on. I'm having trouble getting the sound to play.

The particulars:

Mac Mini (M1) MacOs 13.4.1 of_v20230717_osx_release Xcode 14.3.1

MacBook Pro (Intel) 13,3,1
of_v20230717_osx_release Xcode 14.3.1

Steps taken during the testing.

The sample code from both the basic and fancy examples were copy/pasted into new projects.

I copied the config.make into the new projects and updated. I checked the audio device number and that the source name matched.

The receiver indicated a connection by displaying the IP address displayed in the receiver project.

In the fancy example the waveforms of the Sine wave and file player don't load into the viewport and toggling mute/unmute on both the sender and receiver don't produce sound either.

Here are the console logs

I hope this helps

Hi. I have not used this addon for a while. I would need to check. My biggest suspect is the NDI version. I'll let you know how it goes.

[roymacdonald]

Hi! I just checked and it works on my MacBook Pro i7 macos 11.6.8 using OF from github's master branch. having the config.make file actually bothered so I just deleted it. Then I re-generated the project and compiled. Once done I had to copy the libndi.4.dylib from ofxNDI/libs/NDI/lib/osx/x64 into each app's bundle for example into one of the examples /Users/roy/openFrameworks/addons/ofxSoundObjects-NDI/example-ofxNDISender-barebonesVersions/bin/example-ofxNDISender-barebonesVersionsDebug.app/Contents/MacOS/

which branch/version of ofxNDI are you using?

[bitSpaz]

Hi @roymacdonald,

The version I'm using is NDI 2021-03-02 r121634 v4.6.2

I copied the libndi.4.dylib files from and to the folders specified. I deleted the config.make files and regenerated the projects on both machines. They have been compiled but the audio isn't playing on the receiving machine. The sender's help text indicates that the audio is playing but both the position and positionMS Instances displays 0.

Thanks!

[roymacdonald]

if you try the examples on the send machine, do you get any audio?

[bitSpaz]

No I don't.

[roymacdonald]

What about running it on the same machine, both sender and receiver? Try with the examples. You mention that you are using an intel and an M1 mac. Try on both machines to send and receive on the same machine. M1 macs are sometimes a bit finicky. If this works on both then it is a network issue. Notice that you might need to enable metwork access for these apps on the system preferences > privacy..

[bitSpaz]

I tried sender/receiver on the same machine which didn't produce audio. The receiver is displaying the local ip address so they are connected.

It seems to me that PositionMS should be displaying the position in milliseconds as it does on the ofSoundPlayer example. Does it display position on your machine?

[roymacdonald]

Hi. On my machine it displays the current frame. So what I suspect is that you did not choose the correct audio audio device on either side. Make sure you do. Best if it is the built in audio. On the sender, even when it does not output sound to the local sound device it still needs to connect to it in order to clock the sending through NDI

[bitSpaz]

Hi, From the console: ------- SOUND OUTPUT DEVICES --------- [ 0 ] Apple Inc.: MacBook Pro Speakers API: Unkown API ID: 2 Outputs :2

Which corresponds to this line "soundSettings.setOutDevice(outDevices[0]);"
Is this what you're referring to? If so then it's not the issue.

I also experimented with the network successfully sending audio from the Intel to the Mac mini.

Could this be the problem? 2023-08-07 11:00:42.253269-0700 NDI_Sender_SM23Debug[29108:38181835] [default] CGSWindowShmemCreateWithPort failed on port 0

Thanks

[roymacdonald]

you need to have the output set up properly on both computers. In the first post, in the console log for the sender it shows

------- SOUND OUTPUT DEVICES ---------
[ 0 ] MEI: Panasonic-TV

Probably you are connecting to it as teh output. Make sure you connect to the built in audio.

the other error has to do with the window creation and seems unrelated .https://developer.apple.com/forums/thread/727803

[bitSpaz]

I changed the output device to 1 on the mini but that didn't fix the problem.

However, I unearthed a 2015 MacBook Pro running 10.15.7 MacOS. It used openFrameworks 11.2 and it works! The one thing I did differently was to use install info from the ofxNDI readme, Xcode instruction, Build Phases>Copy Files, click the + , add libndi.4.dylib

I tried this method on the intel MacBook Pro mentioned above. I used a fresh download of ofxSoundObjects-NDI, but it still doesn't work.

Thanks

[roymacdonald]

@bitSpaz so did this solve the problems you've got?

[bitSpaz]

Yes! Thanks so much for you're time.
