  GStreamer | gst-plugins-good | Ver: HEAD CVS
           Summary: [avidemux] Doesn't parse vprp ODML header
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: hadess at hadess.net
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


The vprp ODML header can contain aspect ratio information. This information is
currently ignored.

typedef struct _gst_riff_vprp_video_field_desc {
  guint32  CompressedBMHeight;
  guint32  CompressedBMWidth;
  guint32  ValidBMHeight;
  guint32  ValidBMWidth;
  guint32  ValidBMXOffset;
  guint32  ValidBMYOffset;
  guint32  VideoXOffsetInT;
  guint32  VideoYValidStartLine;
} gst_riff_vprp_video_field_desc;

typedef struct _gst_riff_vprp {
  guint32         VideoFormatToken;
  guint32        VideoStandard;
  guint32        dwVerticalRefreshRate;
  guint32        dwHTotalInT;
  guint32        dwVTotalInLines;
  guint32        dwFrameAspectRatio;
  guint32        dwFrameWidthInPixels;
  guint32        dwFrameHeightInLines;
  guint32        nbFieldPerFrame;
  gst_riff_vprp_video_field_desc FieldInfo[nbFieldPerFrame];
} gst_riff_vprp;

And from the specs at http://www.the-labs.com/Video/odmlff2-avidef.pdf:
The aspect ratio is stored as a DWORD value with a word each storing the x:y
ratio. For example, 1 to 1 is 0x00010001. Standard values for television is 4:3
or 16:9. This value can be used with the frame width and height to calculate
the pixel aspect ratio.
