When I last used guvcview, it muxed both audio and video into an appropriate container format for me, but it was all very configurable. I do recall I went with MJPEG for a video codec.[1] I realize you're not fond of GNOME, but guvcview doesn't require pulling in all of gnome. Though looking at it now, it may require pulseaudio. I haven't tried luvcview, sorry. [1] This video was recorded with guvcview, and then uploaded as-is. http://www.youtube.com/watch?v=kul0eGILCI4 -- :wq
