I've just fixed this bug on my system (or at least I have a very usable
workaround). It is a sound problem. That is why the video in the preview
window is just fine (no sound involved) but as soon as you start
recording it totally craps out.
In my case the preview window was beautiful at 30fps+ with high
resolution, but when recording I was getting more like 1 frame every 2
seconds. That was extremely frustrating because you just had to look at
the preview window to see that the hardware and system was capable of
much better.
I'm using a USB webcam with built in microphone. My hypothesis is that
because cheese isn't getting sound directly from the device but is
getting it piped through pulseaudio/alsa - as soon as it starts to
record and asks for sound, it finds itself having to fight for access to
the device with the sound applications, which just clogs everything up.
The fix is simple. Plug a microphone into your sound card. Go to
System>Preferences>Multimedia Systems Selector, and look at Audio default
input. The Plugin should be ALSA. The device will probably be `default'. That
is NOT what you want. Change the device from `default' to whatever the analogue
input from your sound card is (there is a drop down list) - mine is "ALC 883
Analogue". Avoid the setting "USB audio" which is probably your webcam. On the
video tab change the default input explicitly to your webcam device rather than
default (this last step possibly isn't necessary - but it is what worked for
me).
Now try again. The result in my case was that cheese functioned flawlessly,
albeit with sound provided by an external mike and not the one built into the
webcam.
