Pipewire compatibility #15

Open spagoc opened 3 months ago

spagoc commented 3 months ago

I am asking if PeppyMeter could work with Pipewire. If so a Linux desktop user, using helvum or qpgraph, could connect PeppyMeter to any audio app is running e.g. a web browser playing a youtube video.

I've never tried that. If Pipewire leverages ALSA behind the scenes then it should theoretically handle PeppyMeter as well. But that should be tested.

In order to achieve preliminary Pipewire compatibility and targeting Linux desktop users I did this effort to get feed-backs: [https://github.com/spagoc/PeppyMeter-4-Linux-desktop] (https://github.com/spagoc/PeppyMeter-4-Linux-desktop) The calibration needs improvements. Please give feed-backs.

PS Thanks for PeppyMeter and its wonderful documentation.

Looks good. It looks like you don't use a peppyalsa plugin. Is it because you cannot do that with Pipewire? So you just handle PCM stream in your C program and send amplitude values to the pipe. Does it mean that you cannot handle audio files this way?

Sorry for my am late answer. Yes to your questions, you are right.
