I need to periodically capture 2 usb webcams at the same time then stream the pair to a webpage etc. I'm using an intel Edison as the embedded camera controller. This needs to run in the background so the edison can do other things in response to the images.
I believe this is a simple configuration of existing tools like ffmpeg, gstreamer, fswebcam, mjpg_streamer, etc.
