  GStreamer | gst-plugins-good | Ver: 0.10.7
           Summary: Unable to modify DEFAULT_VIDEOSRC in configure
           Product: GStreamer
           Version: 0.10.7
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: mario_limonciello at dell.com

     GNOME version: 2.21/2.22
   GNOME milestone: Unspecified


There are two parts to this bug.  First off, maintainers and users building the
package aren't able to directly build with the DEFAULT_VIDEOSRC set to anything
other than "v4lsrc".  Rather than reading in from the environment and using
that variable, instead the variable is consistently overridden.  Look at the
configure script around lines 31674-31678.  Here is a snippet for an example:

            DEFAULT_AUDIOSINK="autoaudiosink"
  DEFAULT_VIDEOSINK="autovideosink"
  DEFAULT_AUDIOSRC="alsasrc"
  DEFAULT_VIDEOSRC="v4lsrc"
  DEFAULT_VISUALIZER="goom"
  case "$host" in
    *-sun-* | *pc-solaris* )
      DEFAULT_AUDIOSINK="sunaudiosink"
      DEFAULT_VIDEOSINK="ximagesink"
      DEFAULT_AUDIOSRC="sunaudiosrc"
      ;;
    *-darwin* )
      DEFAULT_AUDIOSINK="osxaudiosink"
      DEFAULT_AUDIOSRC="osxaudiosrc"
      DEFAULT_VIDEOSINK="osxvideosink"
      ;;
  esac

The second part to this bug is that this default should be changed to v4l2src. 
V4L itself has been deprecated since ~2.6.15 and all new devices are developed
against V4L2.

See http://linuxtv.org/v4lwiki/index.php/Development:_Video4Linux_APIs for more
information on V4L.
