Short intro: I'm a long time Linux developer currently working on improving
webcam support in Linux, see:
http://fedoraproject.org/wiki/Features/BetterWebcamSupport
I'm one of the authors of the v4l2 rewrite of the gspca usb webcam driver
framework (which supports more then 100 different cams), this v4l2 rewrite has
been merged into the 2.6.27 kernel and thus will become available in the
official Linux kernel soon.
One of the parts of the v4l2 rewrite has been removing conversion from various
manufacturer cam specific video formats to more normal videoformats from the
drivers, as this really does not belong in kernel space.
As a result of this the gspca subdrivers can generate raw video frames in the
following formats:
#define V4L2_PIX_FMT_SN9C10X v4l2_fourcc('S', '9', '1', '0') /* SN9C10x
compressed bayer
#define V4L2_PIX_FMT_SPCA501 v4l2_fourcc('S', '5', '0', '1') /* YUYV per line
#define V4L2_PIX_FMT_SPCA505 v4l2_fourcc('S', '5', '0', '5') /* YYUV per line
#define V4L2_PIX_FMT_SPCA508 v4l2_fourcc('S', '5', '0', '8') /* YUVY per line
#define V4L2_PIX_FMT_SPCA561 v4l2_fourcc('S', '5', '6', '1') /* compressed
GBRG bayer
#define V4L2_PIX_FMT_PAC207 v4l2_fourcc('P', '2', '0', '7') /* compressed
BGGR bayer
As we do not want to see each application implement (nor having to implement)
support for these various formats, as we like to have one code base and only
one code base for these formats. A library has been written (with me as the
main author) to convert from these formats to BGR24 or YUV420. For more on this
library see:
http://hansdegoede.livejournal.com/3636.html
As such I've been working (for a number of days!) on a patch to add
support for libv4l to xawtv. This has resulted in my doing a whole patch
series, listed in the order in which the patches should be applied.
xawtv-3.95-fixes.patch
--
Some small fixes which are needed for xawtv-3.95 to work with some v4l2 devices
at all.
xawtv-3.95-libv4l2.patch
Use libv4l2 to gain support for all kind of camera specific video formats
xawtv-3.95-no-dga.patch
---
xawtv does not work on many videocards without specifying -nodga, this patch
fixes this by catching the error and continuing as if the server does not
support DGA at all
xawtv-3.95-v4l-conf-user-bpl.patch
--
Allow root to override the detected number of bytes per line, this is needed
to get direct pci transfers to the framebuffer to work on my ati x1950pro
Note that for xawtv to work properly atleast version 0.4.0 of libv4l is needed,
rawhide currently has 0.3.9 and I cannot build 0.4.0 due to an error in the
kernel-headers package.
p.s.
While writing all these patches and with all my recent v4l work in
general I've become quite familiar with the xawtv code, so if you want I
can become a co-maintainer (and push these patches myself).

libv4l will show up in rawhide as soon as a cvsadmin gets around to creating a
cvs module for it, see libv4l'2 review request: bug 456772
Getting this patch into Fedora is important for the F-10 better webcam support
feature:
https://fedoraproject.org/wiki/Features/BetterWebcamSupport
###
A note about the patch, the patch is actually quite simple, as libv4l has been
designed for quick porting of existing apps to libv4l, for this reason libv4l
fully mimicks the raw /dev/video interface (and if no conversion is needed and
for non relevant calls like setting ctrl's, passes through all calls
unmodified).
All that the patch does and all that needs to be changed to use libv4l is
replace the relevant xxx calls on /dev/video with v4l2_xxx calls.
The only special thing about the patch is that it passes the
V4L2_ENABLE_ENUM_FMT_EMULATION flag to libv4l2 on open, this patch tells libv4l2
to report the "emulated" formats in the ENUM_FMT ioctl results. Which libv4l2
does not do be default so that ENUM_FMT only reports the really supported
formats (a TRY_FMT with one of the 2 supported emulated formats can then be done
to see if conversion is supported for the specific device). Given the working of
the v4l2 plugin, enabling the ENUM_FMT emulation is needed.
I've successfully tested this patch with cheese and 2 spca561 cams (quite
popular IC, used by both logitech and creative), 2 pac207 cams (another quite
popular IC), 3 SN9C10X cams (also very popular) and 1 spca501 cam. All of which
do not work without this patch, as gstreamer does not support their proprietary
video formats (and rightfully so).
###
p.s.
While doing a local rpm testbuild of gstreamer-plugins-good with this patch, it
failed because it build a couple of plugins not in the %files list due to me
having to much foo-devel packages installed, can you please add:
"--disable-esd --disable-libcaca --disable-aalib" to the %configure flags to fix
this?
