  GStreamer | gst-plugins-good | Ver: 0.10.x
           Summary: add libv4l2 support to v4l2 gst plugin - required for
                    most new webcams
           Product: GStreamer
           Version: 0.10.x
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: tetromino at gmail.com

     GNOME version: Unspecified
   GNOME milestone: Unspecified


In kernel 2.6.27 and higher, the drivers for gspca and most uvc webcams (i.e.
most USB webcams in existence) require userspace v4l2 clients to do their own
video format conversion. The gstreamer v4l2 plugin (all versions up to 0.10.11,
and the CVS version too, as far as I can tell) currently does not perform this
conversion, hence making the plugin very nearly useless.

Fortunately, Fedora has done the hard work of developing a patch for the v4l2
plugin to use the libv4l2 library to do automatic format conversion.

See
http://cvs.fedoraproject.org/viewvc/rpms/gstreamer-plugins-good/devel/gst-plugins-good-0.10.9-libv4l.patch?view=log

Works so well that Debian and Ubuntu have borrowed and started using it too:

http://packages.debian.org/changelogs/pool/main/g/gst-plugins-good0.10/gst-plugins-good0.10_0.10.11-2/changelog
http://changelogs.ubuntu.com/changelogs/pool/main/g/gst-plugins-good0.10/gst-plugins-good0.10_0.10.10.4-1ubuntu1/changelog


But for reasons unknown, neither Fedora nor Debian nor Ubuntu have bothered to
actually submit the patch upstream! So, I suppose it falls to me, a Gentoo
user, to do it for them...
