Actually, it looks like the one I'm accustomed to is
media-video/guvcview. I haven't played with media-video/luvcview

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.
