Player dosn't work with audio

[CuBa94]

Hello,

Yesterday I installed the latest version of Dicaffeine on my Raspberry 4. For this I first did a clean install of Raspberry Pi OS with desktop (Debian Bullseye) and updated everything.

Now the player does not work for me when I select the setting "Internal Audio Analog Stereo" or "Internal Audio Digital Stereo". The NDI stream comes from ProPresenter 7 with the latest version 7.8.

What is the problem here?

Hi,

can you start the stream as showed in the video (when it does not start) and then open the terminal window and send me the output of command:

yuri2 /tmp/yuri_config_player.xml

Thanks!

Do you mean this?

Yes, thanks - I can see one thing, the audio has 8 channels and the player does not know how to map them to stereo sound. That should be fixed, thanks for reporting. For now - can you limit the sender to only 2 audio channels and check if it helps?

[CuBa94]

Sorry, no i can't limit the sender to only 2 audio channels... ProPresenter sends automaticlly 8 channels... But I'm sending only on Channel 1 and 2.

That's unfortunate, NDI receiver in Dicaffeine detects 8 channels and tries to configure the audio output for it. I'll fix that in the next release - only maximal available channels should be used.

Yes, you are right. Unfortunately, the number of channels cannot be edited in ProPresenter. If you want to test your fix, ProPresenter can be used for free with watermark. You can easily set up an NDI stream and set audio for SDI & NDI in the audio settings.

ProPresenter can be downloaded here: https://renewedvision.com/propresenter/#download

Thanks for your work! Am big fan of Dicaffeine! :-)

[melnijir]

Thanks :-)

I haven't try it yet (seems that ProPresenter is for Mac/Windows and I have only Linux here), but if you want, you can test the new version:

I've added small fix checking the maximal channels count. It's tested only with virtual sound generator, so I am not really sure if it will work.
