First bits of the new stv0600/stv0610 pushed
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi,
As I've written in an earlier mail I've taken a stab at porting over the old qc-usb driver to the gspca framework.
The driver is nowhere complete but I've gotten it to work on my Quickcam Web using the vv6410 sensor. There is some untested support for the HDCS sensors but I need some testing on it (and probably some bug squashing).
Right now the camera streams a raw bayer image that is converted by the libv4l, the bridge supposedly suports some kind of bastardizes jpeg implementation. It's probably not impossible to implement this
together with libv4l but I'm unsure on how much I'm willing to
spend on this.
This is _not_ a pull request. My current plan is to finish support for the hdcs and pb0100 sensors before submitting it mainline.
The mercurial source repository is located at
http://linuxtv.org/hg/~eandren/gspca-stv06xx/
please have a look and let me know how it works for you and/or if you have any comments regarding the style and code.
Best regards,
Erik
