Record synchronized audio and video with V4L2 webcam?

[kung fu buntu]

Is there any application that allows to record synchronized audio and video while it displays what is being recorded?

My webcam is a Logitech Fusion and uses the UVC driver, that means V4L2 support.

Would also like this. Built-in webcam on Acer 5520 - something down the Crystal Eye lane, also V4L(2) compatible.
Looking elsewhere as well - will post back if I find anything.

edit 1:
"Cheese" seems to be the thing to use these days (install from repos). I have recorded video well enough with it, but both video and audio get choppy and out of synch if I add a mic. It has some cool effects for pics, though :3

edit 2:
VLC can also do the job:

Worked for me, at least.

Couldn't really get VLC recording anything and the video/audio got reaaaaly choppy.

Anymore suggestions?

I'm afraid not... The VLC guide worked for me (followed to the letter), so there must be something different about our systems somehow...

I'm sure someone will find a decent solution somehow... Just keep it in your sig, and I'm sure you'll get a bite. You might want to change the wording to indicate that it really is a plea for help rather than a How-To or something. "Have you got synchronised audio/video working with a webcam? Please help me!" - or something to that effect.

Sorry I can't help you :'(

If you are still looking for this, I found this on a Sidux board:

vlc v4l2:// :v4l2-dev="/dev/video0" :v4l2-chroma="YUYV" :v4l2-width=320 :v4l2-height=240

In Ubuntu 8.10 on an HP dv9000, Microdia Pavilion Webcam, it works perfectly.

Hello. I am using gspcav2 and Logitech QuickCam Express. Before upgrading to intrepid, e.g. on hardy, using gspcav1 recording with VLC worked with v4l1. now with v4l2 VLC takes 100% CPU and works tooooo slow. I tried using

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so vlc

to emulate v4l1 but it is even worse. Cheese doesn't work without converting pixel formats:

LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so cheese

but even with pixel formats converted photo taking works, but video recording does not

Any ideas?
