0c45:613e Microdia PC Camera (SN9C120)

[Rod]

Hi,
I have this Prinston camera. It does not work with camorama or cheese,
but i can see the image perfectly well with gstreamer-properties. So
think it is not a driver problem.
Any idea to make it work with some app ?

You will need to install and use libv4l to handle userspace format
conversions since many programs do now know howto handle bayer and
jpeg formats. Also camorama is a v4l1 application and your driver is
v4l2 only.

After installing libv4l try the follwoing from a command prompt
# export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so
# <name of video application to run> eg. camorama, cheese, etc
