  GStreamer | gstreamer (core) | Ver: HEAD CVS
           Summary: filesrc detect if a file is seekable using SEEK_SET and
                    not SEEK_END
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: alessandro at nnva.org

     GNOME version: Unspecified
   GNOME milestone: Unspecified


Under windows playing a matroska file of 4695522630 bytes fails as filesrc
thinks that the file is not seekable.
Filesrc uses this code to determine if a file is seekable:

    off_t res = lseek (src->fd, 0, SEEK_END);

    if (res < 0) {
      GST_LOG_OBJECT (src, "disabling seeking, not in mmap mode and lseek "
          "failed: %s", g_strerror (errno));
      src->seekable = FALSE;
    } else {
      src->seekable = TRUE;
    }

In windows with such matroska file lseek fails with Invalid argument.
Changing the lseek call to lseek (src->fd, stat_results.st_size, SEEK_SET)
works.
