            Bug ID: 762148
           Summary: dashdemux: correctly handle an HTTP-XSDATE that is
                    exactly the size of the date string
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: florin.apostol at oregan.net
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

The code in the gst_dash_demux_parse_http_xsdate() was trying to
handle the case where the string is not null terminated by resizing
the buffer and appending a zero byte. This does not work if the buffer
is exactly the length of the string because the gst_buffer_resize()
function does not re-allocate the buffer, it just changes its size.

If a buffer is passed to gst_dash_demux_parse_http_xsdate() that is
exactly the length of the string, the function fails with an assert
failure in gst_buffer_resize().
