Solved: webcamstudio looks for sun java, but I use openjdk. This allows it to run:

ln -s /usr/lib/jvm/java-6-openjdk-amd64 /usr/lib/jvm/java-6-sun

Installation notes:

On Debian Wheezy, I had to install some dependencies first:

aptitude install libdbus-java libjna-java linux-headers-3.1.0-1-amd64

Then:

dpkg -i webcamstudio_0.57beta4_all.deb

This produced the following output:

Restating the webcamstudio service to update the module Stopping WebcamStudio kernel module: webcamstudio.

There are now WebcamStudio and WebcamStudio Console menu items available (but neither actually seem to start/work). Far as I've gotten. Perhaps it helps someone.

Introduction

Here are discussed the Linux specifics about WebcamStudio.

Details

GStreamer, ffmpeg and libav are available from the package manager of most of the contemporary distributions.
The virtual webcam module is the thing that is a little harder to deploy.
- WebcamStudio is using a forked module of v4l2loopback (previously vloopback) renamed to webcamstudio.
- The problem with the recompiling the module for each kernel is fixed for versions 0.60+ on Debian like systems, since it uses DKMS
The original v4l2loopback kernel module could be used since versions 0.60+ on Debian like systems
On some distributions GStreamer works much better and faster than ffmpeg/libav on the same system (for example this is the case with Gentoo). This should be further investigated.
