            Bug ID: 757605
           Summary: Does not honor H.264 YUV coefficient flag
    Classification: Platform
           Product: GStreamer
           Version: 1.6.1
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
          Assignee: gstreamer-bugs at lists.freedesktop.org

Hi,

The attached two video files should decode near-identically to each other and
to
http://www.imagescience.com.au/kb/images/BeEyeCalibrationImages/colourWedges.jpg.
 (They are encoded with different YUV coefficients, and no other real
differences.) They don't; in Iceweasel the BT.601 is right but the BT.709 is
washed out (the brightest greens are all 255), while in gst-play-1.0, the
BT.601 is too dull (G=233 at the brightest or so) and the other colors
contaminated (e.g. the brightest red has B=15).
