For our application, we need to stream audio along with video from a VOXL to a remote computer in real time. Is it possible to use a mic to capture, then add an audio component to the video stream without making significant software modifications? Also, what would the recommended way to do this be? What interface would you recommend for connecting the microphone? USB?
A USB microphone would be the easiest path. We have never tried this though. voxl-streamer is built using g-streamer, so you should be able to mux in audio there with a little custom code
