Raspberry Pi - Raspbian
ZM 1.25 is already in Raspbian. Newer development packages are available.
You will want libjpeg-turbo from the following repository by adding to your /etc/apt/sources.list
deb http://zarrenspry.info/repos/apt/raspbian testing main deb-src http://zarrenspry.info/repos/apt/raspbian testing main
Add gpg by
wget -O - http://zarrenspry.info/zarrenspry.gpg.key%7Capt-key add -
apt-get install libturbojpeg8 libturbojpeg8-dev
If using the Pi camera, you will need to enable it in raspi-config as well as loading the v4l2 kernel module by adding the following to your /etc/modules
bcm2835-v4l2
Although the camera will can capture high res, you don't have enough RAM currently to do so. Especially if you have the early 256MB model. So ust stick to 640x480.
You should be able to get around 20fps, but if you do anything involving the CPU you will get underruns.
