Chris Bass 19a45554bf dashdemux: remove incorrect timestamp scaling. 
When using a SegmentTemplate element, the timestamps of the buffers
output by dashdemux are incorrect, causing problems downstream.

The reason is that GstMediaSegment start times are calculated (in
gst_mpdparser_get_chunk_by_index) by multiplying segment index by
segment duration and then scaling the result according the `timebase'
attribute from the MPD. However, the segment duration is already a
GstClockTime (i.e., it has already been scaled according to the timebase
from the MPD and converted to a nanosecond value), so multiplying it by
the segment index will give the correct timestamp without the need for
any further scaling.

dashdemux

GStreamer plugin allowing the playback of MPEG DASH streams.

The plugin is based on some basic objects defined in the GStreamer HLS
Demux plugin from the gst-plugins-bad module.

Minimum requirements:
- glib 2.32.1
- gstreamer 0.10.36
- gst-plugins-base 0.10.36
- gst-plugins-good 0.10.31
- gst-plugins-bad 0.10.23

The following patches need in addition to be applied:

isomp4 (from gst-plugins-good):
https://bugzilla.gnome.org/show_bug.cgi?id=677535
https://bugzilla.gnome.org/show_bug.cgi?id=678767
https://bugzilla.gnome.org/show_bug.cgi?id=678772

decodebin2 (from gst-plugins-base):
https://bugzilla.gnome.org/show_bug.cgi?id=685938

To build gst-dashdemux:
./autogen.sh
./configure
./make
sudo make install

To launch gst-dashdemux:
