You have been subscribed to a public bug:
xv driver is having playback issue with webcam capture, it plays green
screen.
It was firstly found when using stock 12.04.3 image, during on
installing step of "Choose a Picture", the webcam view only playback
with green screen, but it still can capture correctly if you hit the
button.
After completely installed 12.04.3 system or upgrade your X driver stack to
lts-raring,
on system with haswell chipset, webcam capture will playback with green screen.
To reproduced this problem we could use:
guvcview
luvcview
mplayer tv:///dev/video0 -vo xv
vlc v4l2:/ //dev/video0 -V xv
On the same hardware system,
To validate that webcam works fine with other output drivers:
luvcview -w
mplayer tv:///dev/video0 -vo x11
vlc v4l2:/ //dev/video0 -V glx
By downgrade to xserver-xorg-lts-quantal also fixes this issue,
its also verified on 12.04.2 stock image with the same webcam.
