           Summary: vp8enc incorrectly sets timestamps based on
                    theoretical framerate
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: blaise at willowgarage.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
      GNOME target: ---
     GNOME version: ---


The vp8enc plugin incorrectly sets timestamps based on the theoretical
framerate. As a result, the following pipeline does not work:

gst-launch v4l2src ! video/x-raw-yuv, width=320, height=240, framerate=30/1 !
ffmpegcolorspace ! vp8enc ! vp8dec ! xvimagesink

vp8enc should copy the timestamp directly from the incoming buffer, as is done,
for example, by theoraenc.
