Webcam Device Driver to support H.264
I have a Creative Live Cam Connect HD (id: 041e:4093) and this webcam has an on-board H.264 encoder. Unfortunately v4l2 only inputs the feed as MJPG.
$ v4l2-ctl --list-formats
ioctl: VIDIOC_ENUM_FMT
...
Index : 1
Type : Video Capture
Pixel Format: 'MJPG' (compressed)
Name : MJPEG
Basically I need to use this webcam to get a H.264 feed. Is there a different driver that I can use to use the on-board encoder instead of having to use Gstreamer to encode the feed on my machine?
Since there are no pre-built drivers to do what I want, I am trying to write my own driver. I found lots of recourses for writing linux drivers but not specifically for webcams. Can you point me to some resources or provide an outline of what I need to do? I never wrote a driver before.

What kernel version are you on ?
As far as I remember, since 3.2 (or was it 3.3?) the h264 support in uvc driver should be there.
If v4l2-ctl doesn't list anything other than MJPG, it's probably because the camera itself doesn't support H264 raw stream, but only supports H264 embedded in MJPG frames (which is what skype/windows uses for h264 encoding cameras).
I suggest you give it a try with the uvch64_src (see
http://kakaroto.homelinux.net/2012/09/uvc-h264-encoding-cameras-support-in-gstreamer/)
If it supports h264, it should be able to work with it (I never tested that
camera though).
