How to get Playstation Eye Camera working on Raspberry Pi? #74

Open jsmath opened 4 years ago

jsmath commented 4 years ago

I am running the latest Raspbian Buster (as of 2-5-2020) on a raspberry pi 3 with a PS3 Eye camera attached. I am able to select the device in the web ui [Current device: USB Camera-B4.09.24.1: Audio (hw:1,0)] and it populates the config.yaml file with "device: 2". I have also used arecord to verify I can record audio to a wav file correctly. I am getting the following error when trying to select an audio reactive effect in the ledfx ui. I suspect the error has something to do with the PS Eye camera having 4 different audio channels. Has anyone got the PS Eye camera working with ledfx on a raspberry pi or otherwise? I am using Python 3.7.3 which is installed by default on my version of Raspbian.

Looks like I found a workaround for this issue. I added the environment variable below and the audio reactive effects are now working in LedFx. I am seeing a bunch of other things printed out on the command line, but I need to review to see if they are expected or if they are errors.

$ export PA_ALSA_PLUGHW=1
