Raspberry pi audio
Hello,
I have a raspberry pi 2 with Ubuntu Server 16.04 and ROS Kinetic Kame installed. No I plugin my Logitech C270 USB webcam and usually I easily get images from it via OpenCV and can process them the way I like. Now I would like to also get the audio and I wanted to ask, If there is someone with knowledge, how to acquire Audio and Video from this webcam within a ROS node, so that I can send it further to another ROS node in the network? I tried a few tutorials and got a module running, using audio_common. But It always has the problem finding the audio source I think.
Please help me, this problem is killing me. thank you in advance!
